摘要

Aminoamida resin modified with acrylate curable by radiation and its preparation process and coating composition curable by energy comprising a component liable to form cross links and a photoinitiator.A resin modified with acrylate aminoamida curable by radiation which is the product of the addition of Michael to a thermoplastic polymeric aminoamida derivative of an unsaturated fatty acid ester is polymerized with a polyol having at least three groups of ester acrylate, the PO (meta) Lu00edmero aminoamida thermoplastic having a number of amine of 40 to 60 mg KOH / g,The proportion of groups (meta) acrylate ester of polyol to the initial amino functional groups of the polymer of aminoamida initial being at least 4: 1, the resin is liquid at 25 u00b0 C and is useful as a component of the resin of various types of coating composition curable by energy. Including paints, varnishes and lacquers, particularly lithographic inks.
