Abstract
An aqueous crosslinkable coating compositions comprising i) an autoxidisably crosslinkable polymer, ii) a not autoxidisably crosslinkable vinyl polymer bearing acetoacetyl groups and iii) acetoacetyl-reactive groups to crosslink the vinyl polymer.
Claims12
An aqueous crosslinkable coating composition comprising as aqueous dispersed components:
- (i) at least one autoxidisably crosslinkable organic polymer containing unsaturated fatty acid residues, and
- (ii) at least one vinyl polymer which is not autoxidisably crosslinkable and bears acetoacetyl functional groups, and wherein said composition has present therein carbonyl-reactive amine and/or hydrazine derivative functional groups which impart crosslinkability to component (ii).
