This invention relates to a radiation curable aqueous coating composition comprising: —from 1 to 99% by weight, relative to the total weight of (1) and (2), of at least one radiation curable aqueously dispersed polyester resin composition (1) 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 polymerized and which is attached to the polyester resin backbone by an ester linkage or a urethane linkage, and—from 1 to 99% by weight, relative to the total weight of (1) and (2), of at least one other olefinically unsaturated compound (2) selected from the group of: water-dispersible compounds (21); water-soluble compounds (22); and/or water-compatible compounds (23) that have a weight average molecular weight of at least 450 Dalton and are different from the reaction product AC.
摘要:
Disclosed are alkyd resin emulsions for coating varnishes, containing a water-insoluble alkyd resin A and a water-soluble alkyd resin B that is used as an emulsifying resin and represents an esterification product of an alkyd resin Ba which can be homogeneously mixed with the alkyd resin A at a weight ratio (Ba to A) ranging between 2:98 and 50:50, alkyd resin A being the resin that is to be emulsified, and an adduct Bb of a C1-C4 alkoxy polyethylene glycol Bba and a cycloaliphatic dicarboxylic acid anhydride Bbb at a mole ration (Bba to Bbb) ranging between 09.95:1.05 mol/mol and 1.05:0.95 mol/mol. Also disclosed is a method for the production thereof, the use thereof for coating substrates selected among textiles, mineral materials, metals, and wood.
摘要:
Radiation curable polyester composition AB, capable of forming solutions or dispersions in water of high solid content which can be produced by mixing or pre-condensing a water soluble, radiation-curable emulsifying resin A which contains ester and acid groups and has an acid number from 20 to 300 mg/g and water-insoluble, radiation-curable polymer B containing ester and/or ether groups, wherein resin A is a reaction product of an alkoxylated polyol A1 having at least 3 hydroxyl groups and 3 to 10 oxyalkylene units per molecule, these oxyalkylene units containing 2 to 4 carbon atoms each, with an &agr;, &bgr;-unsaturated carboxylic acid A2 having each a free carboxyl group per molecule, and a carboxylic acid A3 which is at least tri-functional and wherein polymer B is a reaction product of aliphatic, linear, branched or cyclic alcohols B1 with compounds B2, selected from alkylene oxides B21, dicarboxylic acids B22 and aliphatic lactones B23 having 4 to 12 carbon atoms as well as compounds B3 selected from &agr;,&bgr;-unsaturated carboxylic acids with 1 to 2 carboxyl groups in the molecule, aqueous coating compositions made therefrom, and a method of using these for coating of heat-sensitive substrates.
