Patent ID: 8652759

Claim:
Method of producing an imaged lithographic printing plate comprising: (a) imagewise exposing a lithographic printing plate precursor, (b) treating the imagewise exposed lithographic printing plate precursor with an aqueous developer to provide a lithographic printing plate, the aqueous developer having a pH value of >6 and comprising (i) water, (ii) at least one hydrophilic polymer, comprising (m1) primary, secondary or tertiary amino groups, and (m2) acid groups selected from —COOH, —PO 2 H 2 and —PO 3 H 2 , and (m3) optionally alkylene oxide units —(CHR 1 —CH 2 —O) p —, wherein each R 1 independently represents H or —CH 3 and p is an integer from 1 to 50, and (iii) optionally at least one member selected from surfactants, alkaline reagents, water-soluble film forming hydrophilic polymers, additives selected from organic solvents, biocides, complexing agents, buffer substances, filter dyes, antifoaming agents, anticorrosive agents and radical inhibitors; and (c) directly after treating with the aqueous developer, drying the lithographic printing plate without further rinsing and gumming.
