Abstract
A composition, which is particularly useful as an adhesive, as well as a method of making an adhesive composition, and a method of using an adhesive composition are disclosed.
Claims14
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 RI is CH3, CH2CH3, CH2CH2CH3, 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.

A bonded multi-ply laminate comprising:
- (a) two or more plys comprising one or more substrates selected from the group consisting of:
- plastics, polyethylene, polypropylene, metallized plastics, metallized polypropylene, polyesters, polyamides, nylon, metals, aluminum and paper, and (b) a composition comprising a reaction product of an α,β-unsaturated multi-carboxylic acid ester and a compound (A) having the structural formula:
- wherein R is a polyester or polyesteramide;
- wherein RI is CH3, CH2CH3, CH2CH2CH3, 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, and the 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;
- wherein the composition bonds each substrate ply together.
