Decorative relief finish process
First Claim
1. A process of making a decorative relief finish, said process comprising:
- forming on the surface of an object on which a decorative relief finish is to be formed a partially hardened layer of coating material having an uneven surface with a plurality of projections of different heights;
providing a pressing roll having a surface which is made of a material which is resinous, has a continuous pore structure, is at least semi-hard, and has the properties of water absorption and water retention;
impregnating said pressing roll with a liquid which is capable of being evenly distributed through the pores of said roller material, which will not damage said roller material, and which has an affinity to said coating material; and
pressing and rolling said pressing roll, while impregnated with said liquid, against the top portions of those of said projections above a predetermined height, thereby flattening said projections to said height, the remainder of said projections below said given height being left unflattened, thus forming a decorative relief finish having both flattened and roughened areas.

Abstract
A decorative relief finished surface is formed by applying to the surface of an object or substrate to be patterned an undercoat of coating material to a predetermined thickness, and forming an uneven pattern having a variety of projections on coated surface a plurality of times with a rolling device having a plurality of convex parts of curved continued, disconnected or perforated line shape which are formed in a random manner, with the intervals between the convex parts being substantially equal to each other, or by spraying coating material with a spray gun so as to form a multiplicity of projections of varying height. Then, the top portions of the projections of the partially hardened surface which extend beyond a predetermined height are pressed with a pressing roll, such that the projections are uniformly flattened to a predetermined thickness while the rest of the convex parts are left unflattened. The pressing roll is made of a hard or semi-hard, air-permeable, porous material.
