Abstract of the Disclosure A radiation-sensitive composition is disclosed comprising a polymeric binder which is insoluble in water, but soluble or at least swellable in aqueous alkaline solution and a 2,3,4,4'-tetrahydroxybenzophenone which is partially esterified with (1,2-naphthoquinone 2- diazide)-4- and/or -5-sulfonic acid, which additionally contains either a dihydroxybenzophenone which is completely esterified with (1,2-naphthoquinone 2- diazide)-4- and/or -5-sulfonic acid or a trihydroxybenzo- phenone which is partially or completely esterified with (1,2-naphthoquinone 2-diazide)-4- and/or -5-sulfonic acid. The weight ratio of esterified 2,3,4,4'-tetra- hydroxybenzophenone to esterified di- or trihydroxy- benzophenone varies between about 4:6 and 7:3 and the esterified hydroxybenzophenones, as a whole, are present in a proportion of 5 to 40% by weight, based on the total weight of solids contained in the composition. Also disclosed is a radiation-sensitive recording material comprising a support and a layer containing this composition, which is present on the support.
