PURPOSE:To obtain good moldability and developability by specifying the components of a photosensitive resin compsn. CONSTITUTION:This printing plate material consists of the photosensitive resin compsn. contg. 30-90wt.% polyolefin having 200-30,000 number average mol.wt., 2-30wt.% ethylenic unsatd. compd., 5-50wt.% solid polyolefin which has solubility in a mixture composed of said polyolefin and ethylenic unsatd. compd. and has >=50,000 viscosity average mol.wt. by a Flory method, 0.01-10wt.% photopolymn. initiator, and 0.1-10wt.% at least one kind of compd. selected from the group of N-acylaminoacid amine salt, N-acylaminoacid amide, etc., and condensation product of polyhydric alcohol and polysaccharide acylated compd., etc. The flexographic printing plate which has the excellent moldability and the good developability, dryability, etc., and is suitable for flexography using water-base ink such as corrugated board and paper container printing is thereby obtd. |
