Patent ID: 8580901

Claim:
An aqueous crosslinkable coating composition comprising: water; a water-dispersible polyurethane polymer, comprising: a plurality of urethane linkages; a plurality of cycloaliphatic groups incorporated into the polyurethane polymer through cyclohexane diacid, non-isocyanate compounds, wherein at least one of the plurality of cycloaliphatic groups comprises a structure X-Z-X, and wherein: Z is the cyclohexane ring structure; and each X is an ester group, wherein at least one of the X groups is a divalent linkage group attaches the cyclohexane ring structure to another portion of the polyurethane polymer; a plurality of salt or salt-forming groups; and a plurality of air-curable ethylenically unsaturated groups; and a carbonyl-functional vinyl polymer, wherein the amount of carbonyl functional groups in the vinyl polymer is 3-500 milliequivalents per 100 grams polymer; and carbonyl-reactive amine and/or hydrazine functional groups.
