    Abstract: Manufacture of pressure-sensitive adhesive coatings on flat substrates by coating the substrates with dispersions of copolymers (A) comprising 30 to 99.5 percent by weight of acrylic and/or methacrylic acid esters of C1 to C3 alkanols, 0.5 to 20 percent by weight of monoesters of C3 to C5 Alpha , Beta olefinically unsaturated mono- or dicarboxylic acids and C2 to C6 polyhydric alcohols and/or N-alkoxy-methyl amides of C3 to C5 Alpha , Beta -olefinically unsaturated carboxylic acids, 0 to 50 percent by weight of vinyl esters of C2 to C18 monocarboxylic acids, styrene, acrylonitrile and/or methycrylonitrile and 0 to 15 percent by weight of Alpha , Beta -olefinically unsaturated C3 to C5 carboxylic acids and/or their amides, in liquid hydrocarbons containing, as protective colloids, 25 to 150 percent by weight of the dispersed copolymer (A) of a dissolved copolymer (B) comprising 80 to 99.5 percent by weight of acrylic and/or methacrylic acid esters of C4 to C18 alkanols and 0.5 to 20 percent by weight of monoesters of C3 to C5 Alpha , Beta olefinically unsaturated mono- or dicarboxylic acids and C2 to C6 polyhydric alcohols and/or N-alkoxy-methyl amides of C3 to C5 Alpha , Beta -olefinically unsaturated carboxylic acids, and also optionally up to two molar proportions of a polyvalent isocyanate, based on the sum of the proportions of free hydroxyl and carboxyl groups in the copolymers (A) and (B), and drying the coated substrates.

    Abstract: Print pastes and dye pastes for printing and dyeing fibrous materials based on organic dispersion of cross-linkable copolymers as binders for the pigments. The disperse copolymers, which can be used as binders without emulsions, are prepared by polymerization of (a) monomers which bear N-methylol groups or Nalkoxymethyl groups with (b) comonomers which do not contain any of the groups specified under (a), in (c) an organic liquid in which the copolymer is insoluble, and in the presence of a copolymer of comonomers of groups (a) and (b) which is soluble in (c) and acts as a polymeric emulsifier.
