Radiation sensitive mixture.

摘要

The invention relates to a radiation-sensitive mixture essentially consisting of (a) a water-insoluble binder or binder mixture which is soluble in aqueous alkaline solutions, and (b) a compound which forms a strong acid on irradiation, component (a) being a phenolic resin whose phenolic hydroxyl groups are partially replaced by groups (I) where R<1> is alkyl and R<2> and R<3> are hydrogen or alkyl or R<1> forms a ring with R<2>. This radiation-sensitive mixture is suitable for producing relief structures.
