Abstract
(EN)
An aqueous composition comprising: A) a crosslinkable vinyl graft copolymer comprising 30 to 85 wt% of a polymeric backbone; and 70 to 15 wt% of at least one macromonomer grafted to the polymeric backbone, where the Tg of the macromonomer is in the range of from 15 to 140 0C; where the Tg of the polymeric backbone is < 40 0C; where the vinyl graft copolymer comprises 0.6 to 10 wt % of at least one carbonyl functional vinyl monomer; where the polymeric backbone contains > 75 % of the carbonyl functional vinyl monomers in the vinyl graft copolymer; and B) a hydrazide functional compound; where the ratio of hydrazide functional groups to carbonyl functional groups in the vinyl graft copolymer is in the range of from 0.1 to 1.5; and where the composition comprises < 50 wt% of organic co-solvent by weight of the vinyl graft copolymer.
