PROCESS FOR OBTAINING ADHERENT AND BRILLIANT COATS F 'VABNISH UPON ALL MATERIALS.

Ho Drawing. Application filed June 23, 1927,

The present invention has for its object a process, the object of which is to allow of obtaining both adherent and brilliant coats of varnish upon all materials, upon which ordinary varnishes cannot be applied with simultaneous realization of these two conditions, either by reason of the spongy nature of these materials (paper, fabrics, certain woods, etc.) or because of their impermea- Io bility and the state of their surface glass,

marble, etc.)

The process according to the invention consists in impregnating the surface, which it is proposed to varnish, with a hot solution H of gelatine, which is allowed to coagulate by cooling and dried before applying the varnish thereon.

The gelatine adheres very firmly to the support, even when the latter is impermeable are and presents an absolutely smooth surface; the layer of gelatine, even when it is applied upon a spongy material like paper or fabric, affords after drying, a smooth surface upon which ordinary varnishes spread and adhere perfectly, yielding directly a brilliant coat.

There is preferably employed uncoloured and transparent gelatine. The concentration of the solution utilized may vary accord- Fm ing to the material to be treated. This solution may have additions or not of alcohol, spirits of turpentine or any other product, with a view in particular to retarding its coagulation.

There may be applied upon the surface to be varnished, either a. single coat or several successive coats of this finish, which allows of varying at will the thickness of the transparent coat. The application of the gelatine Serial No. 201,019, and in France July 2, 1 826.

solution may be made with the brush, by im mersion or by any other suitable means.

Upon the support, there may be fixed, before the varnishing, applied ornamentations, cut out in paper, fabric or the like, which ornamentation is fixed with a suitable glue or with a first layer of gelatine. The gelatine solution with which the whole is then impregnated, yields upon drying at very highly stretched film, which energetically presses the ornaments and in particular their contour against the support. After varnishing, there is obtained a uniformly brilliant coat.

In a general manner, the materials treated according to the present process may be coloured, provided that their tints are not soluble in water or capable of being affected by it. The applied ornaments must likewise satisfy the same condition.

It is quite evident that the invention is not limited to the above explanations, but that it is susceptible of modifications. Thus the gelatine, instead of being dissolved in water. might be dissolved in any one of its solvents, for example acetic acid.

lVhat I claim is:

The process of the class described, consisting in applying on the surface which is proposed to varnish, first ornaments cut out of a sheet'of suitable material, second, a solution of gelatine which is allowed to coagulate and to dry before applying the varnish upon it.

In testimony whereof I have signed my name to this specification.
