ABSTRACT:
The invention relates to a usually positive-working radiation-sensitive mixture which contains as essential components a binder which is insoluble in water and soluble in aqueous-alkaline solutions, a 1,2-quinone diazide and a compound which diminishes the developer solubility of the exposed regions by heat treatment, in which the compound which diminishes the developer solubility which is present is at least one urethane of the formula I: ##STR1## in which R.sub.1 is hydrogen or methyl,
