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 wherein the crosslinking material has an acid number of at least 100 mg KOH/g.

A crosslinking material, the crosslinking material comprising the reaction product of a reaction mixture comprising: (ii) ≥70% by weight of a cyclic unsaturated acid anhydride and/or diacid derivative thereof by total solid weight of the monomers from which the crosslinking material is formed; (ii) optionally, an ethylenically unsaturated monomer; and (iii) optionally, an alcohol, amine, thiol and/or water, wherein at least a portion of the cyclic unsaturated acid anhydride and/or diacid derivative thereof is reacted with the alcohol, amine, thiol and/or water, when present; and wherein the crosslinking material has an acid number of at least 100 mg KOH/g.
