Abstract
Official abstract text for this publication.
Provided is an aqueous polyurethane dispersion comprising (a) dispersed particles of said polyurethane, wherein said polyurethane is the reaction product of polyurethane formation reactants comprising (i) one or more polyisocyanate, (ii) a polyol component comprising one or more polyol, and (iv) one or more organometallic compound having the structure wherein n is 0 or 1, t is 0 or 1, r is 0 or 1, p is 0 to 2, q is 0 to 13, at least one of p and q is not zero, M is a metal that is not silicon, —X 1 is —NH 2 or —OH; and —X2 is selected from the group consisting of —SH, —NH 2 , —COOH, and and (b) one or more isocyanate crosslinker having two or more isocyanate groups per molecule.

1 . An aqueous polyurethane dispersion comprising (a) dispersed particles of said polyurethane, wherein said polyurethane is the reaction product of polyurethane formation reactants comprising (i) one or more polyisocyanate, (ii) a polyol component comprising one or more polyol, and (iv) one or more organometallic compound having the structure wherein n is 0 or 1, t is 0 or 1, r is 0 or 1, p is 0 to 2, q is 0 to 13, at least one of p and q is not zero, M is a metal that is not silicon, —X 1 is —NH 2 or —OH; and —X2 is selected from the group consisting of —SH, —NH 2 , —COOH, and and (b) one or more isocyanate crosslinker having two or more isocyanate groups per molecule. 2 . The aqueous dispersion of claim 1 wherein said r is 0, said p is 0 and said q is 2 to 13. 3 . The aqueous dispersion of claim 1 wherein said polyol component comprises one or more polyester polyol, one or more polyether polyol, or a mixture thereof. 4 . The aqueous dispersion of claim 1 wherein said isocyanate crosslinker is a hydrophilically modified polyisocyanate 5 . A method of forming a laminate comprising (A) applying a layer of the composition of claim 1 to a surface of a metal foil or a polymer film, (B) drying said layer or allowing said layer to dry to form a dried adhesive layer, (C) bringing said dried adhesive layer into contact with a surface of a metal foil or a polymer film to form said laminate.
