Photosensitive resin composition for planographic printing edition and basic plate for planographic printing

摘要

In the photosensitive resin composition for planographic printing edition, the hydrophilic polymer which at least possesses the hydrophilic basis 10 weight % above 90 weight % below and inside the molecule of the hydrophilic polymer and/or the chemical compound which obstructs the hydrogen bond between the molecules 0.5 weight % above 20 weight % below it regards the photosensitive resin composition for planographic printing edition which features that it contains vis-a-vis the hydrophilic polymer. In addition, as for the basic plate for planographic printing, the hydrophilic polymer which at least possesses the hydrophilic basis 10 weight % above 90 weight % below and inside the molecule of the hydrophilic polymer and/or the chemical compound which obstructs the hydrogen bond between the molecules 0.5 weight % above 20 weight % below the photosensitive resin composition which is contained building a bridge vis-a-vis the hydrophilic polymer, it is desirable to possess the hydrophilic resin exposure to light layer which becomes. It can handle in the discernment room, development and wiping off operation is unnecessary, at the same time it is superior in hydrophily, decreases the quantity of the wetting water and it offers the basic plate for CTP which greasing it is difficult to do.
