Patented Jan. 31, 1933 UNITED STATES PATENT OFFICE CHARLES E. FOLEY, OF NASHUA, NEW HAMPSHIRE, ASSIGNOR TO NASH'UA GUmD & COATED PAPER COMPANY, OF NASHUA, NEW HAMPSHIRE, A CORPORATION OF MASSACHUSETTS coa'rnn snnrz'r MA'rEnIAn Application filed July 17,

This invention relates to the production of decorative sheet material for ackaging or wrapping articles therein, or or use as the vative sheet material is, preferably, moisture-proof cellophane, or acetate sheeting.

Of the accompanying drawing Figure 1 is a plan viewof a sheet of the product of my invention, with a corner pormaterial, the formula for which may be:

tion rolled over to illustrate the appearance of the other surface of the sheet.

Figure 2 represents a section of said produet', greatly enlarged to illustrate layers of the material.

In the preferred method of practicing the invention, the base material a is cellophane or other transparent sheeting of regenerated cellulose, or a transparent sheeting of cellulose acetate, in the form of a web of indeterminate length. Such web or sheeting is run through, or passed over, acoating mawhich machine applies thinly and evenly a sizing coat I) (Fig. 2) of rather viscose liquid 1? ts Grlycerol pth allic anhydride resin, at hard 22 Chlorinated di phenyl resin, soft 1.8 Chlorinated di phenyl resin, hard 1.8-

Di chlor ethyl ether 7.3

Red pigment 11.5 Calcium carbonate, 14.7 Titanox' i 14.6

1931. Serial No. 551,435.

I do not limit myself to the above formula, since any other suitable formula may be employed, to produce a sizing in the form of a tough resilient coating and which, by reason of its containing solvent material which partly penetrates the transparent sheeting, or by reason of its plasticity when dry, or by reason of other properties, will be sufficiently flexible and adhesive to secure the coating 0 which will now be described.

Very soon after the sizing coating b is applied, and while it is still wet and adhesive, finely comminuted material such as presently described, is caused to fall upon the sizing coating or layer 6. Such deposit may be effected by sprinkling through a shaking screen, excess of the flocks being removed pneumatically, or by spraying," or by other suitable means which will apply the layer or coating a uniformly and completely.

The comminuted material may be cotton flocks, or flocks of wool, silk or rayon. Or it may be finely divided cork, feathers, metal, mica, pigment, or any finely comminuted material adapted to produce a decorative or useful effect.

The final step is to dry the coated sheet or duced, both as to cost of the cellulose derivative and the flocky or comminuted coating, and in the steps of manufacture. It is a tough light-weight sheeting producible in an unlimited variety of colors or shades. Whatever the color or shade may be, both surfaces will be the same because the three layers a b 0 are very thin, and since the layer a. is

transparent, the color or tint of the other layers is visible through said layer a. Said finished material orsheeting is flexible, easyto work, strong, stretchable, and substantially water-proof. It possesses good wearing qualities and combines the decorative an utilitarian qualities and advantages of a soft, velveti', suede-like face on one side, with a sfioot very glossy, bright colored other s1 e.- 5 I do not limit myself to making the prod uct in three layers, as it is possible to make sheeting which fairly approaches that which I have above described, by mixing com minuted or flocky material with coloring material and adheslve material similar to or the equivalent of those hereinbefore described, I and apply a single layer coating to the sheet of cellulose derivative, instead of two successively applied layers. v And it is to be understood that, for some purposes, both surfaces of the sheet of cellulose derivative may be coated as described, instead of only one surface. Having now described my invention, I claim As a new article of manufacture, sheet material consisting of a thin sheet of highly tran 'arent cellulosic material one surface of" w l iichis uncoated and having its other surface completely coated with a colored adherent and resilient vehicle carrying finely comminuted flock material, the said article of manufacture as a whole being characterized by the transmission of color of the comminuted material through the transparent sheet on one side and a suede-like face on the otherside.

In testimony whereof I have afiixed my signature.

CH,ARLES E. FOLEY.
