A process for forming an olefinic resin film on a metal substrate, which comprises

Process for forming a coated film of an olefinic resin

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.

Photocurable composition containing an N-nitrosodiarylamine

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.
