Abstract
A crosslinking material, the crosslinking material comprising the reaction product of a reaction mixture comprising: (i) a cyclic unsaturated acid anhydride and/or diacid derivative thereof; (ii) an ethylenically unsaturated monomer; and (iii) an alcohol, amine and/or thiol, wherein the cyclic unsaturated acid anhydride and/or diacid derivative thereof is partially-esterified by reaction with the alcohol, amine and/or thiol; and wherein the crosslinking material has an acid number of at least 100 mg KOH/g.
Claims26
A crosslinking material, the crosslinking material comprising the reaction product of a reaction mixture comprising:
- (i) a cyclic unsaturated acid anhydride and/or diacid derivative thereof;
- (ii) an ethylenically unsaturated monomer;
- and
- (iii) an alcohol, amine and/or thiol,
- wherein at least a portion of the cyclic unsaturated acid anhydride and/or diacid derivative thereof is reacted with the alcohol, amine and/or thiol;
- and wherein the crosslinking material has an acid number of at least 100 mg KOH/g.
A package coated on at least a portion thereof with a coating, the coating being derived from a coating composition, the coating composition comprising:
- (a) a film-forming resin comprising a functional group having an active hydrogen atom;
- and
- (b) a crosslinking material operable to crosslink the functional group having an active hydrogen atom on the film-forming resin, the crosslinking material comprising the reaction product of a reaction mixture comprising:
- (i) a cyclic unsaturated acid anhydride and/or diacid derivative thereof;
- (ii) an ethylenically unsaturated monomer;
- and
- (iii) an alcohol, amine and/or thiol,
- wherein at least a portion of the cyclic unsaturated acid anhydride and/or diacid derivative thereof is reacted with the alcohol, amine and/or thiol;
- and wherein the coating composition comprises 5 to 30 wt % of the crosslinking material based on the total solid weight of the coating composition.
