Aqueous dispersed polyester resin compositions |
摘要 |
The invention relates to a radiation curable aqueously dispersed polyester resin composition containing an emulsifier D and the reaction product AC of a hydroxy functional polyester resin A and an olefinically unsaturated compound C which can be radically polymerized and which is attached to the polyester resin backbone by an ester linkage or a urethane linkage. The invention also relates to a process for its preparation and to a method of use thereof. |

1. A radiation curable aqueously dispersed polyester resin composition comprising an emulsifier D and the reaction product AC of a hydroxy functional polyester resin A and an olefinically unsaturated compound C which can be radically polymerised and which is attached to the polyester resin backbone by an ester linkage or a urethane linkage, wherein said emulsifier D is the polyesterification product of a fatty acid D1, a polyhydric alcohol D2 having at least three hydroxyl groups per molecule, a carboxylic acid D3 or its anhydride, and a monoalkoxy polyalkylene glycol D4, and wherein:
(a) when the olefinically unsaturated compound C is attached to the polyester resin backbone by an ester bond, the olefinically unsaturated compound C is an unsaturated acid C1 selected from the group consisting of alpha, beta-unsaturated aliphatic monocarboxylic acids, and monoesters of olefinically unsaturated aliphatic dicarboxylic acids, (b) when the olefinically unsaturated compound C is attached to the polyester resin backbone by a urethane bond, the olefinically unsaturated compound C used is an isocyanate-functional reaction product C2 of an unsaturated aliphatic alcohol C21 and a diisocyanate or polyfunctional isocyanate C22 having three or more isocyanate groups per molecule. |
