MIXTURES OF POLYMERS WITH WATER

摘要

Emulsifier-free synthetic resins and mixtures of synthetic resins with water are used as binders for water-borne printing inks and printing varnishes. The resins contain: (a) a polymer resin A containing acid groups which may have been neutralized or partially neutralized and can be prepared by in-situ polymerization of ethylenically unsaturated compounds containing acid groups with further ethylenically unsaturated compounds and condensation with monohydroxy compounds and, if desired, neutralization or partial neutralization, and (b) if desired, a water-insoluble polymer resin B in the form of latex particles which can be prepared by emulsion polymerization of ethylenically unsaturated compounds in the presence of the polymer resin A.
