Water developable photosensitive resinous composition

摘要

A water developable photosensitive resin composition comprising a water soluble polymer, photopolymerizable unsaturated monomer(s) and a photopolymerization initiator, which is characterized in that as the whole or a part of said photopolymerizable unsaturated monomer(s), there is employed a product made by mixing of 1 mole of urea, thiourea or an alkyl derivative thereof and 0.75 to 1.3 moles of an N-alkylol acryl amide or an N-alkylol methacrylamide. The composition is useful for an image formation through a photopolymerization reaction and developable by water treatment to give a soft and rubber like resilient cured product.
