Release composition and photosensitive rubber plate with layer of the same

摘要

A release composition for an aqueous processible photosensitive rubber plate, which comprises 100 parts by weight of a water-soluble high-molecular weight compound such as polyvinyl alcohol and 0.5 to 7 parts by weight of an amino alcohol. An aqueous processible photosensitive rubber plate is made by laminating a layer of the release composition on a layer of a photosensitive elastomer composition usually comprising an elastomer, a photopolymerizable ethylenically unsaturated monomer, and a photopolymerization initiator.
