Abstract: A copolymeric pigment dispersion resin derived from isobornyl (meth)acrylate and one or more other monomers has a number average molecular weight less than about 10,000 and is derived from sufficient isobornyl (meth)acrylate so that a 60 wt. % solution of the resin in propylene glycol monomethyl ether acetate forms a clear solution when combined at room temperature with at least three times the resin weight of odorless mineral spirits. The resin may be compatibly mixed with solvent-borne coating compositions based on polar or on non-polar solvents, and can provide a single factory shader or point-of sale colorant formulation for tinting a wide range of such coating compositions.

Abstract: A pigment dispersion resin may include a copolymer including monomer units derived from isobornyl (meth)acrylate and methyl (meth)acrylate. Monomer units derived from isobornyl (meth)acrylate may be present in the copolymer in an amount greater than about 55% by weight, the copolymer may have a number average molecular weight of 3000 or less, and the resin may be substantially completely soluble in mineral spirits. A method of manufacturing a pigment dispersion resin may include providing monomers dissolved in a solvent, adding a chain transfer agent to the solvent, and copolymerizing the monomers. A pigment vehicle may include a plurality of pigment particles and a pigment dispersion resin. A method of manufacturing a coating composition may include combining a carrier liquid and a pigment vehicle. A method of coating a substrate may include applying a coating composition to the substrate.
