Title:
AQUEOUS ADHESIVE COMPOSITION FOR DRY LAMINATE HAVING CORE/SHELL STRUCTURE
Document Type and Number:
Japanese Patent JP2000119618
Kind Code:
A
Abstract:

To provide an aqueous adhesive for dry laminates having a high adhesion for dry laminate processing.

This aqueous adhesive composition for dry laminates having a core/shell structure is prepared by mixing an emulsion (B) having a core/shell structure, which comprises as a shell a water-soluble copolymer (A) comprising from 1 to 20 wt.% α,β-ethylenically unsaturated carboxylic acid, from 1 to 10 wt.% non-ester carbonyl group-containing unsaturated monomer and an α,β-ethylenically unsaturated monomer which is copolymerizable with these, and a core comprising at lease 0.1 wt.% methacrylic glycidyl ester, at least 0.1 wt.% dimethacrylate compound, from 0.1 to 10 wt.% non-ester carbonyl group-containing unsaturated monomer and an α,β-ethylenically unsaturated monomer copolymerizable with these, with a polyfunctional hydrazide compound at an amount of from 0.1 to 1.0 equiv. of the total amount of the non-ester carbonyl group-containing unsaturated monomers in the core and the shell composing the emulsion as a crosslinking agent.
