Abstract: PURPOSE: To reduce the total exposure time of the entitled plate by using a specified bisacylphosphinoxide as a photopolymerization initiator. CONSTITUTION: This recording medium is made of a composition comprising a low molecular-weight compound having at least one photopolymerizable olefinic unsaturated double bond, such as >=2 or polyfunctional (meth) acrylate, an organic polymer binder (A) and a photopolymerization initiator (B). As the initiator (B), the bisacylsulfinoxide is used and represented by the formula in which R is a 1-4C alkoxy group or a 6-12C aryl group; and each of R and R is, preferably, a prescribed acyl group. The initiator (B) can be embodied by bis(2,6-dichlorobenzoyl)phenylphosphinoxide and the like, and the binder (A) can be embodied by the polymer of the acrylate having a carbonyl group on a side chain, such as a copolymer of ethylene/n-butylacrylate/acrylic acid.
