EBOCESS FOB ORNAMENTING SHEET MATERIAL.

no'nrawin ap lication-mea- July 1,

The present invention relates to a process for coloring sheet material to produce ornamental effects, and particularly to the ornamentation of flexible sheets such as fabrics, paper and the like.

It has been proposed heretofore. to ornament sheet materials by placing a pattern or stencil against the material and then applying a stenciling color by means of a spray gun, the outline or pattern of the design being defined upon the material in this manner. This process'has been performed with a single color or with several colors depending upon the effect desired, in either event the principal result'sought and obtained beinga coloring ot'comparatively high intensity immediatelyadjacentthe edge of the stencil and becoming less intense as the distance from the stencil edge increases.

One of the greatest objections to the ornamentation otmaterials by this process is that the edge of the design adjacent the stencil is ragged and irregular instead of being sharp and clean-cut. This irr'egular' out-line results from the fact thatit is almost impossible to maintain the entire stencil or pattern in close contact with the material, and whereever this is not done the color runs under the stencil. In fact, the outline is sometimes irregular even where the pattern is in direct contact for the reason that the color spreads under the pattern due to the difierences in absorptive qualities of the material at various localities, this being perhaps aggravated by the capillary attraction of the color molecules to pull the color under the stencil.

While it is exceedingly difficult to eliminate the irregular outline resulting from spraying the color against a pattern, it has been discovered that the ornamental effect is reatly enhanced by the application of a c oud coat containing a metallic or other color after the spraying operation. The; effect or" such a coating is to produce a general diffused effect, and to eliminate all sharp changes and contrasts in the design of the pattern, this producing a new and pleasing subdued and diilused appearance which is especially effective when the material is to be subsequently embossed and treated with a Spanish coat. In addition, the cloud coat serves to either render the jagged edges resulting from the spraying operation invisible or to so minimize 1926. Serial No. 119,984,

the appearance thereof as to make their pres ence scarcely noticeable. The cloud coatm'a y be applied by atomizing with a spray gun, or may be put on under a spreading knife of any well known construction in a manner clearly understood by those skilled in the art! in addition to the function of cloudingol" diffusing the color, the cloud coat also functions as a' protective coating. However, if desired, a protective coating can also be put on as an entirely separate operation after the cloud coat has been applied and dried. Such a protective coating may consist of any well known ingredients such as pyro'xylin containing suitable solvents.

After the application of the cloud and protective coats (ii the latterbeindependently applied), the material may be embossed'in any desired mannerdepending upon the final eiiect desired and the use to which the material is to be placed.

As a final step after the-embossing operation, a Spanish coat can be applied. A-Spanish coat is acoat of pyroxylin with the necessary' oils, colors and solvents incorporated therein. This coat is spread upon the embossed coated surface in such manner that it coats only the impressions formed by the embossing, leaving the raised portions comparatively free of such additional coating. This coat generally consists of another color suitably contrasting with the colors in the coats previously applied, bringing out and making more pronounced the embossed pattern by means of the contrast in color, and may be applied by means of a spreading knife.

While in the application of the main stenciling color the stencil or pattern may be ad vantageously used and will produce highly satisfactory results if positioned directly against the material in the customary manner, we have discovered that new and unusual results can be also obtained if the stencil is maintained out of contact with or in spaced relation to the goods and the stenciling color sprayed against the stencil while the latter is so positioned. This produces a very fine shading effect, as the outline of the pattern then becomes vague and illy defined rather than sharp and cleaircut as when the stencil is in direct contact with the material. When the material. is stenciled in this manner, it is subsequently treated with a cloud coat and a ing pyroxylin on cloth such as amyl or ethyl acetate and the oils used to keep such coatings soft, as, for example, castor oil, and used at the same time for mixing thecolors and introducing them into the pyroxylin. The fixing means permanently bind the color to the material and prevent wearing off or cracking of the color during use. It is immaterial to the successful operation of the present invention whether the flexible material or base has been previously coated to provide a suitable background or not, and it is to be understood that the invention can be successfully used in either case.

Having described the invention, what we claim as new and desire to secure by Letters Patent of the United States is:

1. A process for ornamenting flexible sheet material which consists in covering the material with a pattern or stencil, spraying a color containing a fixing means against the stencil or pattern, and applying a coat over the entire material to cloud over sharply defined irregular outlines and to produce a diffused effect thereon.

2. A process for producing a shading-off color effect on fabric which consists in holding a stencil over the fabric and in spaced relation thereto, spraying a color containing a fixing means over the edge of the pattern, and applying a coat over the entire material to cloud over sharply defined and irregular outlines, and to produce a diffused effect thereon.

3. A process for producing a shading-off color effect on flexible sheet materials which consists in holding a stencil or pattern over the material, spraying acolor containing a fixing means against the pattern, covering the entire material with a cloud coating to produce a diffused effect, and subsequently applying a protective coat to the fabric.

4;. A process for producing a shading-off color effect on fabric and the like, which consists in holding a stencil or pattern over the fabric, spraying a color containing a fixing means over the edge of the pattern, covering the entire fabric with a cloud coating to pro-' duce a diffused effect, subjecting the coated fabric to an embossing operation, and thereafter applying a Spanish coat to the fabric. 5. A process for producing a shading-off color effect on fabric and the like, which consists in hol'ding'a stencil or pattern over the fabric and in spaced relation thereto, spraying a color containing a fixing means over the edge of the pattern, covering the entire fabric with a cloud coating to produce a diffused eifect, subjecting the coated fabric to an embossing operation, and thereafter applying a Spanish coat to the fabric.

In testimony whereof we have hereunto set our signatures.
