Abstract
Abstract A water-soluble resin for packaging ink comprising the reaction product of fumarated or maleated rosin and a compound containing two secondary amine groups is disclosed. A resin with a higher softening point may be obtained by substituting a dicarboxylic acid, such as adipic acid or isophathalic acid, for part of the fumarated or maleated rosin. Water varnishes, pigment bases, and water based inks containing the resin are disclosed.
