Document Type and Number:
Japanese Patent JP5896636
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a water-dispersed adhesive composition capable of forming an adhesive excellent in adhesiveness to a non-polar body to be adhered such as polyethylene and polypropylene at low temperature.SOLUTION: The water-dispersed adhesive composition includes: a (meth)acrylic polymer provided by polymerizing a monomer composition comprising primarily (meth)acrylic acid alkyl ester with 1-18C alkyl group; and latex containing a rubber component incompatible with the (meth)acrylic polymer, wherein the mixing ratio ((meth)acrylic polymer/rubber latex) of the (meth)acrylic polymer to the latex ranges from 95/5 to 25/75 in terms of the solid content weight ratio. The storage elastic modulus, obtained by drying the water-dispersed adhesive composition at 100°C for 3 min. is 1 MPa or less in the temperature range of -15 to 25°C, as measured by dynamic viscoelastic measurement with shear strain with 1 Hz frequency.
