Patent ID: 7119144

Claim:
A method of bonding two or more substrates, comprising the steps of: (a) applying a composition to a first substrate, the composition comprising an α,β-unsaturated multi-carboxylic acid ester and a compound (A) having a structural formula: wherein R is a polyester or polyesteramide; wherein R I is CH 3 , CH 2 CH 3 , CH 2 CH 2 CH 3 , or wherein compound (A) is an acetoacetate terminated polyester or polyesteramide, having an acid value of 0.1 to 5, and containing from 5 to 80 mole percent of at least one aromatic multi-carboxylic acid, in the presence of at least one catalyst, selected from the group consisting of sodium alkoxides, potassium alkoxides, sodium acetylacetonates, and potassium acetylacetonates, wherein said composition has a reactive equivalent functionality ratio of α,β-unsaturated multi-carboxylic acid ester to compound (A) of 0.67:1 to 1.75:1; and; (b) contacting at least one second substrate to the applied composition.
