Abstract: A process for forming an olefinic resin film on a metal substrate, which comprises[A] forming a multilayer coated film consisting of an olefinic resin film as a surface layer portion and a cured epoxy resin film as an under layer portion on a metallic substrate by a single coating operation using a multilayer film-forming coating composition comprising as main resinous components(a) a solid powder containing an olefinic resin having a melt index of 0.3 to 80 g/10 minutes,(b) a solid powder containing a polar group-containing modified olefinic resin having a melt index of 0.3 to 80 g/10 minutes, and(c) a film-forming resinous material comprising an epoxy resin having a number average molecular weight of about 350 to about 4,000 and an epoxy equivalent of 150 to 3,800 and a curing agent therefor, and[B] then heat-bonding an olefinic resin lining material to the olefinic resin surface layer of the multilayer coated film.

Abstract: A photocurable composition comprising a major part of a polymerizable compound with at least two ethylenically unsaturated bonds in one molecule thereof, and minor parts of a photosensitizer and a nitrosodiarylamine compound is described. The nitrosodiarylamine compound serves to suppress thermal polymerization of the photocurable composition. The photocurable composition is especially suitable for use in making paints and printing plate materials.

Abstract: A photopolymerizable vinylurethane monomer and a composition thereof useful for the preparation of printing plates and reliefs, the vinylurethane monomer being expressed in general by the following chemical formula: ##SPC1##In which R represents a hydrogen atom or a methyl group, X represents an alkylene or alkane-triyl to -hexayl group or polyalkyleneoxy group having a number average molecular weight not exceeding 2000 or 3000 respectively, and n represents a corresponding number to the valency of the group X selected from 2 to 6, and A represents an alkyleneoxy group or polyalkyleneoxy group of the formula: ##EQU1## where R is a hydrogen atom or a methyl group and m is a positive integer of 1 to 11, and the composition comprising the vinylurethane monomer, ethylenically unsaturated liquid monomers and a photosensitizer.
