Abstract

Heat-sensitized polymer latex mixtures, wherein they contain from 0.05 to 10% by weight, based on polymer, of a heat-sensitizer and, as stabilizer, from 0.1 to 10% by weight, based on polymer, of a sulphonamide corresponding to the general formula ##STR1## IN WHICH R represents alkyl, chloroalkyl or cycloalkyl with 8 to 30 carbon atoms or alkaryl with 10 to 30 carbon atoms, PA1 R.sub.1 and R.sub.2 independently of one another represent hydrogen, chloromethyl, methyl, ethyl, phenyl; PA1 m is an integer from 0 to 50 and PA1 R.sub.3 represents hydrogen, alkyl, alkaryl, aryl or --(CHR.sub.1 --CHR.sub.2 --O).sub.m H with the above meanings for R.sub.1, R.sub.2 and m.
