ABSTRACT:
A light-sensitive mixture comprising a water-insoluble binder soluble in aqueous alkaline solutions, and the reaction product of a naphthoquinonediazidesulfonyl halide with a mixture composed of a low molecular weight compound having a definite structure and molecular size containing at least one phenolic hydroxyl group, and of a polymeric compound having recurring units, each of which contains at least one phenolic hydroxyl group. The mixture is useful in producing printing plates and photoresists and has the advantage that the naphthoquinonediazidesulfonic acid ester contained therein is non-explosive.
