A METHOD FOR DEVELOPING A PRINTING PLATE PRECURSOR

摘要

A method for developing a printing plate precursor comprising the step of immersing the precursor in an aqueous alkaline developing solution comprising a (co) polymer comprising a monomeric unit which is represented by the following formula (I) : wherein L is a linking group; R1, R2 and R3 independently represent hydrogen or an alkyl group; R4 represents an optionally substituted hydroxyaryl group; x = 0 or 1; y = 0 or 1 and when y = 0 then x = 1 and L is further bound to C* to form a cyclic structure.
