A liquid coating composition comprising a resin solids content comprising (i) a binder solids content comprising at least one hydroxyl-functional binder A and 0.5 to less than 5 wt. % of at least one polyurethane resin B with functional groups selected from the group consisting of hydroxyl groups, free isocyanate groups and blocked isocyanate groups and (ii) at least one cross-linker C, wherein the at least one polyurethane resin B is present as particles having a melting temperature of 40 to 200&#xb0; C.

Hydroxy-functional (meth)acrylic copolymers and coating composition

This invention relates to copolymers which contain hydroxyl groups and which are based on vinyl esters of monocarboxylic acids, wherein the copolymers which contain hydroxyl groups have an OH number of 110-170 mg KOH/g, an acid number of 5-35 mg KOH/g and a number average molecular weight M.sub.n of 1500-8000 g/mole and are obtainable by the polymerisation of A) 5-20% by weight of one or more vinyl esters of saturated monocarboxylic acids, B) 10-30% by weight of one or more aromatic vinyl hydrocarbons, C) 41-55% by weight of hydroxy-functional, polymerisable, unsaturated monomers, and D) 0-40% by weight of further polymerisable, unsaturated monomers, wherein component C) contains C1) 40-70% by weight of one or more hydroxyalkyl esters of .alpha.,.beta.-unsaturated monocarboxylic acids, C2) 1-10% by weight of one or more lactones, and C3) 30-55% by weight of one or more reaction products of an .alpha.,.beta.-unsaturated monocarboxylic acid with a glycidyl ester of a saturated .alpha.,.alpha.-dialkylalkane-monocarboxylic acid or of a saturated .alpha.-alkylalkane-monocarboxylic acid, and the sum of components A) to D) and the sum of components C1) to C3) add up to 100% by weight in each case.

Copolymers which contain hydroxyl groups and a method of producing them

Coating agents are described, that are suitable for the production of pigmented or transparent top coatings, based on hydroxy-functional (meth)acrylic copolymers, aliphatic and/or cycloaliphatic polyisocyanates, solvents, and customary lacquer additives and pigments. They are free from epoxy resins and nitrocellulose and contain as binder
