The present invention provides a (meth)acrylic resin composition comprising a carboxylic acid group produced by heating a (meth)acrylic-based resin (C), wherein the (meth)acrylic-based resin (C) is obtained by polymerizing a monomer mixture (A) containing 80 to 99 wt % of a linear alkyl (meth)acrylate and 1 to 20 wt % of tertiary-butyl (meth)acrylate, in the presence of an acrylic acid ester-based crosslinked elastic particle (B) that is obtained by mixing and polymerizing 0.5 to 5 parts by weight of a polyfunctional monomer having at least two non-conjugated double bonds per molecule, with respect to 100 parts by weight of a monomer mixture containing 50 to 100 wt % of an alkyl acrylate monomer and 0 to 50 wt % of an alkyl methacrylate monomer. This composition can be used to produce a film having excellent chemical resistance (in particular, sun-screening agent resistance).

Corrosion-resistant, self-priming coatings that are curable by ultraviolet energy and methods for coating surfaces using such coatings have been provided. In an exemplary embodiment, a method for coating a surface includes formulating a chromium-free, self-priming coating, applying the chromium-free, self-priming coating to the surface, and curing the chromium-free, self-priming coating with ultraviolet light.

Disclosed is cross-linking process for cross-linking polymeric chains in a coating composition. In one embodiment the process utilizes a Hantzsch dihydropyridine reaction to form reaction products including cross-linking polymeric resin chains having beta-keto ester functions using a source of aldehyde and a source of ammonia or a primary amine to form a permanent dihydropyridine bond between the beta-keto ester functions. The novel cross-linking reaction can occur at lower temperatures compared to typical cross-linking reactions and can occur in aqueous solutions that have a neutral to mildly alkaline pH of from 6 to 11. The novel cross-linking reaction provides many advantages to performing cross-linking of polymeric chains in coating resins.
