Abstract: Carboxyl-containing polycondensation products having glass transition temperatures T.sub.G .gtoreq.20.degree. C. obtained from anhydrides of tricarboxylic or tetracarboxylic acids and diols, diamines or amino alcohols are used for cosmetic purposes, in particular as hair treatment compositions.

Abstract: A radiation-sensitive mixture essentially consisting of(a) a binder or binder mixture which is insoluble in water but soluble in aqueous alkaline solutions and(b) a compound which forms a strong acid on exposure to radiation,wherein the binder (a) used is a phenolic resin in which from 5 to 50% of the phenolic hydroxyl groups have been replaced by .beta.-halogenated alkyl carbonate groups, is suitable for the production of relief structures.

Abstract: A radiation-sensitive mixture, essentially consisting of(a) a binder or binder mixture which is insoluble in water but soluble in aqueous alkaline solutions,(b) a compound which forms a strong acid on exposure to radiation and(c) one or more organic compounds which suppress the solubility of (a) in aqueous alkaline solutions,wherein component (c) is an organic compound of the general formula (I) ##STR1## where R.sup.1 and R.sup.2 are each hydrogen, alkyl, alkoxy, aryl or aralkyl and R.sup.3 and R.sup.4 are each alkyl, cycloalkyl, aralkyl, aryl or a radical ##STR2## where n is from 1 to 5 and R.sup.5 is alkyl, alkoxy, aryl or aralkyl, or R.sup.3 together with R.sup.4 form a five-membered to seven-membered ring via --(CH.sub.2).sub.m -- in which m is from 4 to 6, is suitable for the production of relief structures.

Abstract: A radiation-sensitive mixture useful for producing relief structures consists essentially of(a) a water-insoluble binder or binder mixture which is soluble in aqueous alkali and(b) a compound which forms a strong acid on irradiation,wherein component (a) contains at least one group ##STR1##

Abstract: A radiation-sensitive mixture, essentially consisting ofa) a binder or binder mixture which is insoluble in water but soluble in aqueous alkaline solutions,b) a compound which forms a strong acid on exposure to radiation andc) an organic compound which contains an acid-cleavable carbamate unit,is suitable for the production of relief structures.
