Description
Patented Sept. 24, 1929 UNITED STATES SHINJIRO E0311, TOKYO, J' AIAN STENCIL SHEET.
No Drawing. Application filed December 31, 1927, Serial No. 2441,04 7, and in Japan December8, 1927.
My invention relates to improvements in stencil sheets for use in duplicating manuscript and typewritten documents, drawings and the like, consisting of a sheet of fibrous 5 material coated or impregnated'with a coating material which is impermeable to ink and can be stencilized by the pressure of a writing stylus or the impact of the type of a type writing machine. 7
It has previously been proposed to produce a stencil sheet of this kind consisting of a fibrous base coated with a solution of a cellulose ester, such as cellulose acetate or nitrate, in a suitable solvent, combining therewith a tempering agent, such as castor oil or a heavy hydrocarbon oil. It has further been proposed to produce a stencil sheet of a fibrous base coated with a solution of esters of polysaccharides in a volatile solvent, combining with a tempering agent, such as naphthenic acid glycerides or chlorinated naphthalene.
The stencil sheet according to the present invention comprises a fibrous base coated or 2 impregnated with a coating material consisting of a solution of esters of polysaccharides and quince oil.
Quince oil is obtained from the seeds of the quince, Og dom'd oulgm'is, Pers, or Pymc Japom'ca (cultivated in Asia and Europe).
Quince oil is miscible with a solution of esters of polysaccharides, and the mixture .remains a homogeneous and flexible coating on the base material after the evaporation of the solvent.
The present invention is an improvement on. my earlier invention described in Patent No. 1,587,954, of June 8, 1926, in that it produces a stencil sheet having a coating of the desired softness but without stickiness.
I have found that while naphthenic acid glycerides acts as a plastifyingagent, the resulting coating is not sufficiently soft to'permit the characters to cut through by the light pressure of a type, unless it is rather excessively used. This is duetothe excessive high viscosity of naphthenic acid glycerides. On the contrary, quince oil has a viscosity lower than that of castor' oil, or-naphthenic acid glycerides thus producing a sheet which, is
softer and more pliable even tho the quince oil is used in comparatively small quantities.
The present invention also is an improvement over that described in Patent No. 1,67 9,034 of July 31, 1928, diclosing the use of squalene, which is a hydrocarbon obtained from liver oils of sharks, as a softening ma-' terial.
Squalene is an unsaturated liquid hydrocarbon, C H and when exposed to air forms a hard skin similar as in the case of ordinary drying oils, so that when it is used as a coating material it results in certain drawbacks, the sheet becoming sticky or hard when kept a long time before use. Moreover, the source of squalene is not as abundant and it is diiiicult to obtain squalene i in a pure state. rather expensive.
As compared therewith, quince oil is of comparatively low viscosity, and when used as a softening agent it forms a homogeneous coating which is stronger and more durable than can be obtained by the use of squalen'e or other hydrocarbon oils. The coated sheet not only is pliable but also durable and stable, and is easily stencilized, yielding excellent copies, and, moreover, it is unaffected by climatic conditions and may be kept for a long period of time.
In the carrying out of the invention, a sheet of fibrous base, such as Japanese yoshinopaper, is coated or impregnated'with a coating material prepared b dissolving esters of polysaccharides, suc as starch acetate, mannan acetate, cellulose acetate, cellulose nitrate, in any suitable solvents, such as acetone, ethyl alcohol, butyl alcohol, amyl acetate, ethyl acetate, benzol, toluol,
Consequently its use is petroleum benzine or a mixture of them, and P mixing therewith quince oil. If desired, a suitable quantity of a tempering agent, such as natural or artificial resins, fatty acids, naphthenic acid, oils, blown oils, polymerized oils, fats, waxes, glycerin esters, or glycol esters of fatty acids, naphthenic acid glycerides, solid hydrocarbons, chlorinated naphthalene, methyl or ethyl phthalate, butyl phtha1ate,butyl stearate, butyl tartrate, triphenyl or tricres'yl phosphate, or a mixture of them, may be added to the above coating material. The coating material may also be added into the paper stuff in a mixing hollander during the paper making operation.
The proportions of ,the ingredients of the coating material may vary according to several circumstances. The following is an example Parts by weight Cellulose nitrate 10 Acetone 20 Ethyl alcohol. 20 Ethyl acetate 20 Amyl acetate 40 Benzol 20' Quince oil 20 Oleine 5 Stearine L 5 The term esters of polysaccharides'is intended to include not only one of definite esters of polysaccharides, but also a mixture of them.
What I claim is 1. A stencil sheet consisting of a base of fibrous material and a coating including esters of polysaccharides and quince oil.
2. A stencil sheet consisting of a base of fibrous material and a'coating including esters of polysaccharides, quince oil and tempering agents.
In testimony whereof I aflix my si ature.
