Abstract

A photosensitive composition comprising (1) a maleic anhydride adduct of 1,2-polybutadiene having a molecular weight of 10,000 or higher, (2) at least one photosensitizer and/or at least one photosensitive crosslinking agent, and, if necessary, (3) at least one acrylic monomer. This composition can be developed with water or a polar solvent such as an alcohol, and its layer formed on a support provides a printing plate. When the acrylic monomer is contained, the composition is suitable for use in flexographic printing.
