Abstract:
An aqueous adhesive composition comprising:a condensation polymer obtained by subjecting i) 100 parts by weight of a copolymer essentially consisting of from 99.5% by weight to 50% by weight of the following (A) monomer, from 0.5% by weight to 50% by weight of the following (B) monomer and from (0% by weight to 49.5% by weight of the following (C) monomer, ii) from 10 parts by weight to 200 parts by weight of the following (D) alkoxysilane and iii) from 0 part by weight to 100 parts by weight of the following (E) alkoxysilane to hydrolysis-condensation, andan aqueous medium, which contains said condensation polymer:(A) An unsaturated monomer represented by the general formula (1): ##STR2## wherein R.sup.1 is a hydrogen atom or a methyl group; and Q is --OR.sup.2 or --NR.sup.3 R.sup.4 where R.sup.2 is a monovalent organic group containing at least one amino group or ammonium salt group, and R.sup.3 and R.sup.4 are each a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or a monovalent organic group containing at least one amino group or ammonium salt group;(B) an alkoxysilane monomer represented by the general formula (2):R.sup.5 Si(OR.sup.6).sub.n (R.sup.7).sub.3-n ( 2)wherein R.sup.5 is a monovalent organic group containing at least one polymerizable unsaturated carbon-carbon bond; R.sup.6 is an alkyl group having 1 to 3 carbon atoms or an alkoxyalkyl group having 2 to 6 carbon atoms; R.sup.7 is a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; and n is an integer of 1 to 3;(C) an ethylenically unsaturated monomer other than the foregoing components (A) and (B);(D) an alkoxysilane represented by the general formula (3):R.sup.8 Si(OR.sup.9).sub.n (R.sup.10).sub.3-n ( 3)wherein R.sup.8 is a monovalent organic group containing at least one polymerizable unsaturated carbon-carbon bond; R.sup.9 is an alkyl group having 1 to 3 carbon atoms or an alkoxyalkyl group having 2 to 6 carbon atoms; R.sup.10 is a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; and n is an integer of 1 to 3; and(E) an alkoxysilane represented by the general formula (4):R.sup.11 Si(OR.sup.12).sub.n (R.sup.13).sub.3-n ( 4)wherein R.sup.11 stands for an amino group-containing alkyl group, epoxy group-containing alkyl group or an alkoxyl group having 1 to 3 carbon atoms, R.sup.12 stands for an alkyl group having 1 to 3 carbon atoms, R.sup.13 stands for a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, and n is an integer of 1 to 3.
