Patent ID: 8389608

Claim:
An aminoplast-polythiol composition comprising a contact product of: a) an aminoplast resin composition; and b) a polythiol composition comprising thiol ester molecules having an average of two or more thiol groups per molecule; wherein the polythiol composition comprises: (i) a thiol ester composition comprising thiol ester molecules derived from an unsaturated natural source oil; (ii) a hydroxy thiol ester composition comprising hydroxy thiol ester molecules derived from an epoxidized unsaturated natural source oil; (iii) a crosslinked thiol ester composition comprising crosslinked thiol ester oligomers having at least three thiol ester monomers derived from an unsaturated natural source oil or from an epoxidized unsaturated natural source oil, and connected by polysulfide linkages having the structure —S Q —, wherein Q is an integer greater than 1; or iv) any combination thereof.
