Document Type and Number:
WIPO Patent Application WO/2023/068302
Kind Code:
A1
Abstract:
[Problem] The present invention addresses the problem of developing a chloroprene polymer latex adhesive composition that has excellent adhesiveness to soft polyvinyl chloride resins and also has excellent thermal creep resistance with an adherend. [Solution] A method for producing an adhesive composition characterized by mixing a chloroprene polymer latex (A) that includes a chloroprene polymer and has a gel component content of 15-95%, a (meth)acrylic polymer emulsion (B) that includes a (meth)acrylic polymer having a monomer component represented by formula (1), the Tg of the (meth)acrylic polymer being -30°C to 20°C, and a chlorinated polyolefin resin (C) so that the mass ratio (a:b) of the solids fraction (a) of the chloroprene polymer in the chloroprene polymer latex (A) and the solids fraction (b) of the polymer in the (meth)acrylic polymer emulsion (B) is 90:10 to 65:35. (In general formula (1), R1 represents a hydrogen atom or a methyl group, and R2 represents a linear or branched C1-18 alkyl group.)
