A thermosetting transparent coating material, its preparation and use. The coating includes (meth)acrylate (co)polymer having a number-average molecular weight of from 1,000 to 6,000 daltons, a glass transition temperature of &#x2212;15 to +70&#xb0; C., and a hydroxyl number of from 80 to 200 mg KOH/g; polyester having a number-average molecular weight of from 800 to 6,000 daltons, a hydroxyl number of from 80 to 200 mg KOH/g and an acid number of from 1 to 50 mg KOH/g, comprising, based on the polyester, from 30 to 70% by weight of cycloaliphatic structural units; a blocked polyisocyanate in which the blocked polyisocyanate groups are attached to flexibilizing structural units which, as part of a three-dimensional network, lower its glass transition temperature; and blocked polyisocyanate in which the blocked polyisocyanate groups are attached to hardening structural units which, as part of a three-dimensional network, raise its glass transition temperature.

Disclosed is a method for making nongelled addition polymers, especially carbamate functional additional polymers from linear unsaturated anhydrides. The method comprises reacting an unsaturated linear anhydride with an active hydrogen compound to provide two monomers comprising polymerizable C&#x2550;C bonds, at least one of said monomers comprising an acid functional group; polymerizing the polymerizable C&#x2550;C bonds of the two monomers to provide an acid functional polymerization product; and reacting the acid functional polymerization product with an epoxy functional compound to provide a nongelled addition polymer, wherein the disclosed method does not include a step comprising the physical removal of any acid functional monomers or polymerization products. Also disclosed is a curable coating composition containing the resulting carbamate functional polymer, as well as a coated substrate comprising a cured film resulting from the application and curing of the disclosed curable coating composition.

Disclosed is a method for making nongelled functional addition polymers from linear unsaturated anhydrides. The method subjects a linear unsaturated anhydride compound, an active hydrogen compound, and an epoxide compound to reaction conditions such that each of the following three reactions occur: (i) polymerization of polymerizable C&#x2550;C bonds, (ii) ring opening of an anhydride functional group of the linear unsaturated anhydride compound by the active hydrogen compound to create an acid functional group, and (iii) reaction of the acid functional group resulting from the anhydride ring opening with the epoxide compound. At the time of reaction (iii), the acid functional group resulting from the anhydride ring opening may be selected from an ethylenically unsaturated monomer, a polymer, or both. In one embodiment, the method does not include the physical removal of any acid functional monomers or polymerization products. Also disclosed are a curable coating composition and a coated substrate.
