LOW GAIN POSITIVE PRE-PRESS PROOFING SYSTEM

摘要

A positive-acting photosensitive proofing element is constructed with a thermal adhesive layer having a Tg between 45 DEG C and 60 DEG C, said adhesive comprising a polymer or copolymer derived from an ethylenically unsaturated monomer and 0.5 to 40% by weight of a polyvinyl ether polymer as a flexibilizer.
