Abstract

The present invention relates to (1) a latex for an adhesive composition, the latex for an adhesive composition (A) containing a polymer of an ethylenic unsaturated monomer (a1), a surfactant (a2), and an aqueous medium, the polymer of an ethylenic unsaturated monomer (a1) having a carboxy group, the polymer of an ethylenic unsaturated monomer (a1) having an average particle diameter of 0.30 to 5.00 μm, (2) a latex for an adhesive composition, the latex for an adhesive composition (A) containing a polymer of an ethylenic unsaturated monomer (a1), a surfactant (a2), and an aqueous medium, the polymer of an ethylenic unsaturated monomer (a1) having a carboxy group and a crosslinked structure, and (3) an adhesive composition containing the latex for an adhesive composition (A) and a chloroprene based polymer latex (B).
