Claim:
1. A process for decorating a surface of a substrate comprising the stages of: printing a three-dimensional decorative pattern having a tactile effect on the surface of a polymer film using resin to provide a decorated surface on the polymer film, coating the surface of the substrate with a layer of chromium oxides and then with a further layer of paint product, placing the decorated surface of the polymer film and the surface of the substrate in contact with each other and providing thermal energy thereto to transfer the three-dimensional decorative pattern onto the surface of the substrate such that the further layer of paint product is covered by the three-dimensional decorative pattern, and detaching the film from the substrate, wherein said polymer film is formed of at least one layer of extruded material, wherein the three-dimensional pattern is formed from resins which comprise at least one component selected from: cellulose acetate, cellulose acetobutyrate, cellulose nitrate, cellulose propionate, epoxides, melamine-formaldehyde, polyamides, polyamide imide, polyacrylonitrile, polybutene-1, polybutylene terephthalate, polychlorotrifluoroethylene, polydiallyl phthalate, polyethylene, polyether imide, polyether ketone, polyether terketone, polyether sulphones, polyethylene terephthalate, phenol formaldehyde, polyimide, polyisobutylene, polymethacrylimide, poly-4-methylpentene-1, polyoxymethylene, polyformaldehyde, polyacetal, polypropylene, polyphenyl ether, polyphenylene oxide, polyphenylene sulphide, polysulphone, polythiophen, polytetrafluoroethylene, polyurethane, polyvinyl butyral, polyvinyl chloride, chlorinated polyvinyl chloride, polyvinylidene chloride, polyvinylidene fluoride, polyvinyl fluoride, regenerated cellulose, silicones, urea-formaldehyde, unsaturated polyester, polydimethylsiloxane, wherein the resins also comprise an expanding additive capable of causing an increase in volume of the three-dimensional decorative pattern on the substrate, and wherein the increase in volume is caused by exposure to temperatures within the range between 40 and 300° C. which causes the formation of gases, vapours, foam and/or gel or chemical reactions capable of generating macromolecules of larger volume than that of the starting reagents.
