AQUEOUS ADHESIVE COMPOSITION, METHOD FOR PRODUCING THE SAME AND LAMINATED BODY

摘要

PROBLEM TO BE SOLVED: To provide an adhesive solving a foaming property in coating which was a problem of a conventional emulsion type adhesive and capable of forming a laminated product excellent in gloss and water resistance. SOLUTION: The aqueous adhesive composition comprises a carbonyl group-containing polymer emulsion (F) and a compound (G) containing two or more hydrazino groups. The carbonyl group-containing polymer emulsion (F) is obtained by carrying out emulsion polymerization of monomers (a1) to (a5) and (a7) capable of forming a polymer having -20 to 0°C glass transition temperature with a polyfunctional monomer (a6) having two or more radically polymerizable unsaturated double bonds by using a reactive emulsifying agent (c1) having a radical-polymerizable functional group in which recurring number of ethylene oxide units is 7-20 and an unreactive emulsifying agent (c2) not having a radical-polymerizable functional group at a weight ratio [(c2)/(c2)] of (1/1) to (1/5) and has 150-250 nm average disperse particle diameter.
