  • Acrylated polyamides
    Patent number: 8476334
    Abstract: A radiation-curable acrylate-modified aminoamide resin which is the Michael addition product of an aminoamide thermoplastic polymer derived from a polymerised unsaturated fatty acid with a polyol ester having at least three (meth)acrylate ester groups, the aminoamide thermoplastic polymer having an amine number of from 40 to 60 mgKOH/g, the ratio of the initial (meth) acrylate groups of the polyol ester to the initial amino functional groups of the aminoamide polymer being at least 4:1, is liquid at 25° C., and is useful as the resin component of various types of energy-curable coating composition, including inks, varnishes and lacquers, especially lithographic inks.
    Type: Grant
