Abstract

A photopolymerizable recording material comprising a transparent support film, a thermoplastic photopolymerizable photoresist layer, and a flexible covering film on the exposed surface of the photoresist layer. The material is in the form of a roll. The end faces of the roll are covered with glued-on covering disks to prevent squeezing out of photopolymerizable substance.
