A process for laminating a photopolymerizable film to a substrate which comprises the steps of (a) applying to a substrate surface or a photopolymerizable film surface which is preformed and nonliquid, a liquid which is substantially nonphotosensitive to actinic radiation and which consists essentially of at least one nongaseous ethylenically unsaturated compound containing at least one ethylenic group having a boiling point above 100°C. at normal atmospheric pressure and being capable of forming a high polymer by addition polymerization (b) laminating the substrate and preformed nonliquid photopolymerizable film through the applied liquid whereby excess liquid is present during the lamination and is forced along at least one edge of the laminated substrate and film whereby adherence is obtained of the substrate to the film through the liquid; (c) exposing imagewise to actinic radiation the photopolymerizable film and the liquid; (d) removing unexposed areas of the photopolymerizable film and the liquid from the substrate.
