Abstract: The invention relates to a process for the desensitisation of 1,2-naphthoquinone-2-diazide-sulphonic acid esters, which are processed especially to give radiation-sensitive coating solutions for semiconductor substrates or printing plate carrier materials. The reaction mixture originating from the preparation of the 1,2-naphthoquinone-2-diazide-sulphonic acid esters is treated with a polymeric organic desensitising agent. A desensitised mixture, consisting essentially of 1,2-naphthoquinone-2-diazide-sulphonic acid ester and a polymeric desensitising agent, is then precipitated from the mixture.

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.
