POSITIVE TYPE COLOR PROOFING FILM AND MAKING THEREOF

摘要

Photopolymer positive surprint color proofing film based on epoxy acrylate monomer exhibits low dot gain, low time dependence of toning and good tonal range. Binder can be methylmethacrylate/ethyl acrylate/acrylic acid copolymer, preferably crosslinked with zinc ions and plasticized with a second acrylate monomer and a mixture of triacetin and trimethylol propane.
