    摘要: A waterborne film-forming composition is provided that includes a stable aqueous dispersion of a mixture of a polyester polyol and a carboxylic acid-containing acrylic polymer polyol having a weight ratio of polyester polyol to acrylic polymer polyol in the range of 10:90 to 30:70; and a polyisocyanate crosslinking agent where the equivalent ratio of hydroxyl groups to isocyanate groups is from 0.8:1 to 1.7:1. The polyol component is prepared by polymerizing a mixture of ethylenically unsaturated polymerizable monomers that includes at least one carboxylic acid group-containing monomer; at least one primary alcohol group-containing monomer; and at least one glycidyl ester of an aliphatic saturated monocarboxylic acid in the presence of at least one polyester polyol. Multi-layer composite coatings and coated substrates are also provided.

    摘要: Described is a method of applying several coats to an electrically conducting substrate by applying an undercoat using electrophoresis, stoving the undercoat, applying direclty to the stoved undercoat a coloured and/or special-effect overcoat made of an aqueous coating material containing colour and/or special-effect pigments and including as binder: A) 50 to 85 % by wt. of hybrid binders made from polyesters and (meth)acryl copolymers having a hydroxy value of 100 to 350 mg KOH/g and an acid value of 20 to 60 mg KOH/g, B) 0 to 20 % by wt. of binders different from A, C) 15 to 50 % by wt. of free or blocked polyisocyanates and/or compounds based on triazine which crosslink with the hydroxy groups of component A to form ether and/or ester groups, at least 50 % by wt. of the (meth)acryl copolymers in component A being produced in the presence of at least 20 % by wt. of the polyester(s) in component A. The overcoat is followed by a transparent top coat.
