Patent ID: 8383321

Claim:
A method for developing a heat-sensitive lithographic printing plate precursor comprising the step of immersing said precursor in an aqueous alkaline developing solution comprising a (co)polymer comprising (i) a monomeric unit which is represented by the following formula I: wherein L is a linking group; R 1 , R 2 and R 3 independently represent hydrogen or an alkyl group; R 4 represents an optionally substituted hydroxyaryl group; x=0 or 1; and y=0 or 1 and when y=0 then x=1 and L is further bound to C* to form a cyclic structure, and (ii) one or more monomeric units derived from the monomers selected from the group consisting of styrene, acrylic acid, methacrylic acid, alkylacrylate, alkyl methacrylate, allyl methacrylate, hydroxyalkykl methacrylate, and hydroxyalkyl acrylate.
