Thickening agents comprising a crosslinked polymer powder

摘要

The present application relates to a thickening composition comprising (a) 10-50% by weight, based on the total composition (a)+(b), of a crosslinked hydrophilic water soluble or swellable liquid dispersion polymer and (b) 50-90% by weight, based on the total composition (a)+(b), of a crosslinked polymer or copolymer of an unsaturated carboxylic acid in powder form, which is especially useful for thickening printing pastes for multicolour jet-printing.
