A photosensitive polymer composition containing the following components A and B is presented.
A. 100 parts by weight of polyether-ester amide comprising (a) at least one compound selected from the group consisting of aminocarboxylic acids having 6 to 15 carbon atoms, lactams having 6 to 15 carbon atoms and nylon mn salts wherein 10 ≦ m + n ≦ 30, (b) at least one poly-(alkylene oxide) glycol having a number average molecular weight of 200 to 6000, and (c) at least one dicarboxylic acid having 4 to 20 carbon atoms; and
B. 10 to 200 parts by weight of at least one photopolymerizable vinyl monomer having a terminal ethylenically unsturated bond and having a boiling point of at least 150°C.
This photosensitive polymer composition is extremely effective for use in a photosensitive flexographic printing plate developable in water or an alcohol.
