Abstract

This invention makes available a photopolymerizable material containing at least one polymeric binder, photopolymerizable monomer and, at least one photoinitiator, and having a special shear modulus and a specific thickness. These photopolymerizable materials are used in processes for preparing images, especially multiple color proofs. Temporary supports and pigmented transfer materials specifically designed for the preparation of multiple color proofs are described. A pigmented element having a pigmented transfer layer with a polymeric component of polycaprolactone, polytetrahydrofuran and mixtures thereof is disclosed.
