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═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.

摘要： A coating for improved resistance welding of galvanized steel parts or sheets comprises a binder, and a metal phosphide pigment, preferably a ferrophosphorus pigment, having a particle size of from about 0.1 to about 30 microns. The pigment can also include up to about 40% by weight of an additional metal such as tin, aluminum or lead, which can be combined with the metal phosphide in pigment form or deposited onto the surface of the particles. The coating can be applied to either the faying or non-faying surfaces of the galvanized steel, or to the resistance welding electrode, and may be removed, if desired, after the welding operation.The advantages of the present invention include a significant reduction in welding current and an increase in the weldability lobe width, a restoration of the dynamic resistance beta peak, and an increase in electrode life.
