Tris-(hydroxyphenyl) lower alkane compounds as sensitivity enhancers for o-quinonediazide containing radiation-sensitive compositions and elements

摘要

A radiation-sensitive composition comprising an admixture in a solvent of: at least one alkali-soluble binder resin, at least one photoactive compound and an effective sensitivity enhancing amount of at least one tris (hydroxyphenyl) lower alkane compound; the amount of said binder resin being about 60% to 95% by weight, the amount of said photoactive component being about 5% to about 40% by weight, based on the total solids content of said radiation-sensitive composition.
