ABSTRACT:
Liquid additive, which is substantially insoluble in water, for a pigmentary printing paste for use in printing on textile fibers and fabrics, wherein the additive comprises a surface-active, non-ionic liquid product having a molecular weight of between 1,000 and 20,000 and formed by condensing one or more alkylene oxides, and preferably propylene oxide, with a compound having one or more atoms of active hydrogen. The pigmentary printing paste is in the form of an emulsion or semi-emulsion of the oil-in-water type and contains a synthetic thickening agent which is soluble in water with a rate of at least 20% of dry material and which is swollen by alkaline agents. The thickening agent is formed by the copolymerization of at least 20% of one or more unsaturated carboxylic acids having 3 to 4 carbon atoms and, if need be, with one or more other unsaturated monomers. The printing paste also contains the finely dispersed pigment, the binding agent, which is a copolymer of unsaturated monomers, and an emulsifying agent plus the other conventional ingredients used in such pastes.
