[0001]

[Industrial applications]

 The present invention relates to a transfer sheet used for manufacturing stained glass.

[0002]

[Prior Art]

 Stained glass is beautiful and has a high decorative effect, but it is not easy to manufacture and is generally expensive.

As an inexpensive stained glass that replaces the full-scale stained glass, there is one in which a pattern is silk-screen printed directly on a glass plate with a thermosetting or ionizing radiation curable ink. Since it is necessary, productivity is low, and the pattern becomes unclear, so it is not widely used.

Apart from this, there is also a stained glass in which a transparent polyvinyl chloride film having a pattern printed with a transparent colored ink is laminated on a glass plate. This type of material has poor workability on site because the film part cannot be cut with a glass cutter. In addition, when used for a certain period of time, the vinyl film sags due to the effects of sunlight, etc. and the appearance is damaged.

[0005]

[Problems to be solved by the device]

 An object of the present invention is to provide a transfer sheet for easily and inexpensively manufacturing stained glass having a beautiful appearance.

[0006]

[Means for Solving the Problems]

 The transfer sheet for producing stained glass of the present invention basically comprises, as shown in FIG. 1, a transparent release agent layer (2), a transparent colored pattern layer (3), and a transparent release layer (3) on a transfer mount (1). It is preferable that the transparent adhesive layer (4) and the transparent adhesive layer (4) are provided in that order. However, if the transfer mount and the pattern layer have sufficient releasability, the release layer can be omitted, and the pattern layer and the glass layer can be omitted. The adhesive layer is not necessary if a high adhesive strength with

For the transfer mount, a known material such as a film of polyester such as polyethylene terephthalate, a film of polyolefin such as polypropylene, or a material obtained by laminating polyolefin on extrusion-coated high quality paper may be used.

Since the pattern layer is required to have weather resistance and light resistance, the ink used for printing the pattern layer can be prepared from vehicles such as methyl (meth) acrylate, ethyl (meth) acrylate, and butyl (meth) acrylate. Fluorine resin such as acrylic resin or vinylidene fluoride, which is a homopolymer or a copolymer, or those containing a mixture thereof as a main component is used, and pigments such as isoindoline, perylene red, cyan blue, carbon and quinacridone Those in which organic pigments, inorganic pigments such as ultramarine, patina, vermilion, rouge, cobalt blue, carbon black, yellow lead, and titanium white, and weather resistant pigments are dispersed are preferable. The amount of the pigment blended should be within a range that allows sufficient coloring without impairing the transparency of the ink. It goes without saying that a black-based ink mainly composed of carbon black is used to express the pattern for partitioning each color portion of the stained glass. In addition to the pigment, an ultraviolet absorber such as benzotriazole-based, benzophenone-based, salicylate-based, and fine zinc oxide particles may be added. The pattern layer may be printed by a known method such as a gravure method or a silk screen method.

The pattern is a copy of a real stained glass pattern. The pattern of stained glass usually has a plurality of closed area groups separated by black-colored lines, and these closed areas are transparently colored. However, other patterns may be used as long as they have a stained glass appearance.

The adhesive is preferably colorless and transparent, but may be colored and transparent as long as it has little effect on the color of the design. Suitable ones are thermoplastic resins such as acrylic resins and vinyl chloride / vinyl acetate copolymers. From the viewpoint of weather resistance, preferred are acrylic resins having a glass transition temperature of 60 ° C. or higher (more preferably 90 ° C. or higher), vinyl chloride / vinyl acetate copolymers, and chlorinated polyvinyl chloride. If further weather resistance is required, the above-mentioned UV absorber is added. The release agent may be the same as that used in the conventional transfer sheet, and if it is transparent, it may be colored as long as it does not impair the color like the adhesive. A thickness of the release agent layer of 1 μm is sufficient. The type of resin used is a thermoplastic resin such as acrylic resin, polyvinyl chloride, vinyl chloride vinyl acetate copolymer, etc. A resin similar to the layer may be used. When weather resistance is particularly required, the ultraviolet absorber as described above is added here as well. Both the adhesive layer and the release agent layer may be formed by known coating means.

To manufacture a stained glass using the transfer sheet of the present invention, the following may be performed.

On the glass plate, a curable resin-based primer such as polyurethane-based, polyester-based, epoxy-based or acrylate-based primer is applied and semi-cured to such an extent that the tackiness disappears. As shown in FIG. 2, the transfer sheet of the present invention is superposed on the surface of the glass plate (7) on which the primer layer (6) is provided, heated and pressed, and the transfer mount (1) is peeled off when they are bonded. If necessary, on the transfer layer, thermosetting resin such as polysiloxane, polyester, polyurethane, epoxy resin, ultraviolet or electron beam curing type resin such as urethane acrylate and epoxy acrylate, acrylic resin, fluorine resin, etc. Provide a surface protection layer with weather resistant paint such as grease. The semi-cured primer is completely cured during the transfer process and the protective layer formation process. In this way, the stained glass can be manufactured.

Depending on the paint used for forming the surface protective layer, the solvent may exude and cause “pattern collapse” that attacks the pattern layer. To prevent this, a transfer sheet having a solvent-resistant intermediate layer (5) between the release agent layer (2) and the pattern layer (3) is used as shown in FIG. Good.

The resin forming the intermediate layer may be a cured resin of a thermosetting resin such as polyurethane or an epoxy resin as long as it is transparent, or an acrylic resin, a polyester, or a solvent-resistant and heat-resistant resin. As an excellent additive, silica, alumina, magnesium carbonate, precipitated barium sulfate or the like may be added in an amount of 15 to 60 parts by weight based on 100 parts by weight of the resin. The thickness of the intermediate layer is about 0.5 to 2.0 μm.

[0015]

[Action]

 The transfer sheet of the present invention can be obtained by cutting the sheet according to the size of the glass plate to be made into stained glass and then performing the transfer work to obtain the stained glass. It is possible to manufacture beautiful stained glass with an arbitrary pattern, without the trouble of cutting glass and film as with ready-made products.

【Example】

 A 26 μm thick polyethylene terephthalate film “X-45” (manufactured by Toray) was prepared as a transfer mount, and a colorless and transparent release agent containing a mixture of vinyl chloride-vinyl acetate copolymer and acrylic resin was used. It was applied so as to have a thickness of 1 μm. Acrylic resin-based colored transparent ink (isoindrinone for yellow ink, cyan blue for blue ink, and perylene for red ink was used as the coloring agent) on the release agent layer. Using this, an abstract pattern resembling stained glass was gravure printed, and then an acrylic resin adhesive was gravure coated to a thickness of 2 μm to obtain a transfer sheet of the present invention.

By applying a polyurethane-based primer (made by Morohoshi Ink Co., Ltd.) to a glass plate having a thickness of 5 mm so that the thickness after curing becomes 20 μm, and heating at 150 ° C. for 7 minutes to semi-cure it, The surface was tack-free. The transfer sheet was placed on the primer layer, heated and pressed at a temperature of 200 ° C. for 3 minutes, and then the transfer mount was peeled off.

A colorless and transparent acrylic resin-based paint is applied on the transfer layer and heated at a temperature of 150 ° C. for 20 minutes to completely cure the primer layer and to dry the coating film to form a surface having a thickness of 50 μm. A protective layer was provided. The obtained stained glass had high transparency and was beautiful.

[0019]

[Effect of the device]

 By using the transfer sheet of the present invention, it is possible to easily manufacture on-site a stained glass with a beautiful appearance, which has better workability than stained glass in which a polyvinyl chloride pattern printing film is laminated on a glass plate. The cost of this stained glass is 1/5 to 1/10 that of full-scale production of stained glass.
