Abstract: A print paste composition contains, as binder, a curable polymer which is free of N-methylol groups and which contains anhydride-forming dicarboxylic acid and/or dicarboxylic anhydride groups which can react with hydroxyl groups in the cotton or other textile substrate and/or with hydoxyl or epoxy groups in the curable polymer.

Abstract: Reverse phase polymer particles having a size below 10 .mu.m are provided as a solid product comprising a solid dispersion of the particles in a wax matrix which is solid at 20.degree. C. and which melts below 250.degree. C. The product may be made by dissolving the wax into the organic liquid phase of the product of a reverse phase emulsion polymerisation process followed by distillation of the organic liquid and cooling of the resultant product. The product is generally in particulate form and can be used as a flocculant or viscosifier, especially as a textile print paste thickener.

Abstract: A flocculant, viscosifier or other water soluble or water swellable particulate polymer is formulated as a block having a dimension of at least 10 mm and which comprises a wax matrix in which the polymer particles are dispersed. The block can be made by blending polymer powder with the molten wax matrix and cooling and solidifying it. The block is of particular value for releasing flocculant into a flowing stream of suspension.
