Abstract

A metal pattern on a support is formed by imagewise exposing a material having a flexible support bearing a light-sensitive resin layer whose softening point is at least 30 C. and is raised by light exposure, and pressing the layer in contact with a flexible electrically conducting metal layer on an electrically insulating support while heating to a temp. greater than the softening point of the resin before exposure but less than the softening point after exposure, thereby transferring a stratum of resin the unexposed areas to the metal layer and thereafter etching all the metal from the unprotected areas. The resin preferably has a softening point of 60-150 C. after exposure and may be a polyester of one or more dihydric alcohols and one or more dicarboxylic acids, at least one dicarboxylic acid residue having the group -CH = CH-CO-. Exemplified resins are 1, 4-butane diol polycinnamylidene malonate, a pentamethylene terephthalate/pentamethylene benzene diacrylate copolymer, and a pentamethylene azelate/pentamethylene benzene diacrylate copolymer. The resins may contain sensitizers, plasticizers and colorants.
