摘要

PROBLEM TO BE SOLVED: To obtain an aq. compsn. for elution of a photosensitive flexographic plate which shows elution property and plate making property the same as or higher than a chlorine-based org. solvent and which causes little pollution and has no inflammability. SOLUTION: This aq. compsn. for elution of a photosensitive flexographic plate consists of the following compsns. The compsns. are (a) 5 to 40 wt.% of monoalkylglycol, (b) 30 to 75 wt.% of org. solvent except for monoalkylglycol, having 150 to 300 deg.C boiling point under normal pressure and essentially comprised of carbon, hydrogen and/or oxygen, (c) 1 to 15 wt.% of surfactant, and (d) 10 to 30 wt.% of water.
