Abstract: A stain resistant coating composition includes: urethane acrylate core-shell particles including (1) a polymeric acrylic core; and (2) a polymeric shell including a urethane linkage. The polymeric shell is formed from a reaction mixture including an isocyanate and a polyol. The polyol is substantially free of a six or more consecutive methylene group chain and/or the polyol is formed from monomers comprising a monomer content including at least 10 wt % substituted polyol and/or substituted polyacid and/or at least 25 wt % polyol or polyacid containing cyclic content, based on the total weight of the monomers forming the polyol.

Abstract: A crosslinker composition is prepared from a reaction mixture including: (a) a prepolymer including a reaction product of a prepolymer mixture including: (i) a polyfunctional isocyanate; and (ii) a first compound comprising two or more active hydrogen groups, where the polyfunctional isocyanate and/or the first compound comprising two or more active hydrogen groups includes a greater than two functional isocyanate and/or active hydrogen groups, respectively; and (b) a polyfunctional hydrazide. The crosslinker composition is not self-crosslinkable. The crosslinker composition has an acid value of at least 15 based on total resin solids of the crosslinker composition.
