Abstract:
A process for the production of a coating on a substrate by dry transfer of a compound having an affinity for said substrate, wherein a surface of a transfer element is brought in contact with said substrate, said surface of said transfer element being at least partly impregnated with said compound, characterized in that a transfer element whose impregnated surface is flat and uniformly impregnated is placed in contact with a substrate containing a three-dimensional surface topography consisting of relatively high exposed parts and relatively low recessed parts whereby said exposed parts and said recessed parts differ in height by less than approximately 100 .mu.m, so as to selectively apply the compound/coating onto the relatively high exposed parts of the substrate, leaving the relatively low recessed parts essentially free of compound, wherein said compound comprises a reactive functional group, and/or hydrolyzable reaction group, which reacts with groups present on the substrate surface, and reacting said functional and/or hydrolyzable group with said groups present on the substrate surface.
