PROBLEM TO BE SOLVED: To provide an ethylene-(meth)acrylic acid copolymer polyvalent metal ionomer-based aqueous dispersion excellent in dispersibility, film formability and coating workability, and giving coating film with good low-temperature heat sealability, stick resistance, heat-resistant adhesiveness, rustproofness, etc. SOLUTION: The aqueous dispersion is obtained by dispersing an ethylene-(meth)acrylic acid copolymer ionomer containing polyvalent metal ions at≥1 mol% based on the (meth)acrylic acid, 12-30 wt.% in (meth)acrylic acid content and 0.01-300 g/10min in melt flow rate in water with an amine at≥40 mol% based no the carboxy groups of the copolymer. The solid content of this aqueous dispersion is 5-50 wt.%. A laminate is obtained by coating a substrate with the aqueous dispersion followed by drying. COPYRIGHT: (C)2004,JPO |
