(57) [Summary] [Purpose] To obtain an anti-adhesion layer which has good releasability from a flexible photosensitive resin plate and is not affected by any environment. A composition for an anti-adhesion layer for a photosensitive resin printing plate, which is developable with an aqueous processing liquid, characterized in that the composition contains a silane-modified polyvinyl alcohol represented by the following general formula 1. An anti-adhesion layer composition for a photosensitive resin printing plate. [Chemical 1] (In Chemical Formula 1, R represents a hydrogen atom, a hydroxyl group, an alkyl group having 1 to 6 carbon atoms or OM, and M represents a hydrogen atom, Indicates alkali metal and ammonium. l is 1000 to 2 000, m are 10-500, n shows the integer of 1-10. ) |
