Provided is a latex composition suitable for use in a one-pack adhesive that exhibits excellent normal adhesive strength to adherends such as cloth, leather, and paper. Also provided is a one-pack aqueous adhesive using the latex composition. This latex mixture contains: 100 parts by mass, in terms of solid content, of a chloroprene polymer latex having a pH of at least 12; and 10-50 parts by mass, in total, of at least one aqueous dispersion selected from among terpene phenol resin emulsions, acrylic latexes having a glass transition temperature of -40°C to -10°C, and epoxy resin emulsions having a carboxyl group and a pH of 8.0-11.0. It is preferable that the chloroprene polymer has a gel content of 5-30 mass%, the number-average molecular weight of the toluene-soluble portion is 200,000 to 500,000, and the molecular weight distribution is 2.0-4.0. The latex composition can be suitably used as a one-pack aqueous adhesive for bags and shoes. |
