The solvent resistance poly- (the vinyl acetal) the radiation sensitivity composition and the element which are included

摘要

Be able to use the radiation sensitivity composition in order to produce the positive type picture formation element where the solvent resistance is improved, the particular composition although planographic printing edition is produced, is useful. The particular composition the poly- (vinyl acetal) of the specification which shows the tolerance which is improved vis-a-vis the printing chemicals and radiation absorptive chemical compound includes the polymer binder of the alkaline solubility which is.
