Flat goods are printed, and coated with a synthetic, by (a) with appln. of heat, providing the flat goods with a surface layer of a thermoplastic synthetic material which has affinity for printing dyes and which prevents the migration of the dye, and (b) printing the surface by the transfer printing method, by dry heat treatment with an auxiliary substrate printed with a dye which sublimes at 100-300 degrees C. The flat goods may be of wood, chipboard, mineral wool, metal, ceramic, glass, natural or synthetic stone, foams, natural or synthetic fabrics, synthetics such as polyethylene, PTFE, silicones, natural or synthetic rubber, titanosilicates, PVC, or polyvinyl (chloro)acetate. Wooden flat goods may be in the form of furniture. High quality printing is obtd. on goods which could previously not be printed, or only poorly. The method is simple, avoids a wet treatment stage, and may be carried out in 1 step. Dyes which dissolve, sublime or migrate easily can be used, without the need for a later fixation step. Photographically exact reproduction of patterns with all the half-tones, can be obtd. The prods. resist ageing, fats, waxes, fuels, heat, ultra-violet light, solvents, acids, alkalies, salts and gases. |
