Aqueous acrylate-epoxy silane crosslinker adhesive dispersion composition

Claim 1

An aqueous adhesive dispersion composition of pH of 8 to 12 containing 25 to 75% by weight of water having dispersed therein reaction product of A and B, as defined below: A. a water insoluble binder polymer having the following structural formula: ##STR7## vinyl unit I nitrogen unit II acrylate unit III where R 1 and R 2 , which can be same or different are selected from H, lower-alkyl groups of 1 to 4 carbon atoms, halogens, --CH 2 COOR, --COOR, and --CH 2 COOH groups where R is a lower alkyl group of 1 to 8 carbon atoms; R 3 is selected from H and lower alkyl groups of 1 to 8 carbon atoms, at least or portion of R 3 radical being H to give free carboxyl groups; R 4 and R 5 , which can be same or different, are selected from H, --COOH and --COOR groups, where R is as defined above; X is derived from copolymerizable vinyl monomers and is different from the acrylate unit III; Y is a nitrogen-containing radical of unit II which is derived from a nitrogen-containing monomer; radical Y is selected from the following radicals: ##STR8## where R 6 is selected from H, --R 7 NR 8 and --R 7 OH; R 7 and R 8 being same or different lower alkyl radicals of 1 to 5 carbon atoms; R 9 is a heterocyclic nitrogen-containing group selected from substituted ethylene urea groups; R 10 is a heterocyclic nitrogen-containing group selected from pyridyl groups; and B. an effective amount, to effect crosslinking of the binder polymer, of a silane containing both alkoxy and epoxy functionalites.
