ANIONIC POLYMER MIXTURES HAVING REDUCED FOAM FORMATION IN WATER

摘要

Anionic polymer compositions of (a) an acid-group-containing polymer A which was obtained by polymerization of carboxyl-group-containing ethylenically unsaturated compounds with other ethylenically unsaturated compounds in the presence of volatile basic neutralization reagents, and, if appropriate, (b) a water-insoluble polymer B in the form of latex particles, which can be prepared by emulsion polymerization of ethylenically unsaturated compounds in the presence of the polymer A, have reduced foam formation as binders in water-borne printing varnishes and printing inks.
