    Abstract: Polymerisable anthranilic acid esters are obtained by heating acrylic or methacrylic acid esters containing hydroxyl groups with isatoic anhydride in an organic inert medium at temperatures of from 30* to 150*C in the presence of strong basis. They may be polymerised alone or in combination with other monomers by the methods of bulk solution suspension or emulsion polymerisation. Cross-linkage is possible even with the aid of polyisocyanates, formaldehyde and formaldehyde resins.

    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 IN WHICH R represents alkyl, chloroalkyl or cycloalkyl with 8 to 30 carbon atoms or alkaryl with 10 to 30 carbon atoms, R1 and R2 independently of one another represent hydrogen, chloromethyl, methyl, ethyl, phenyl; M IS AN INTEGER FROM 0 TO 50 AND R3 represents hydrogen, alkyl, alkaryl, aryl or -(CHR1-CHR2-O)m H with the above meanings for R1, R2 and m.
