The present invention provides a latex composition suitable for use in a single-liquid type adhesive which exhibits an excellent normal bonding strength to a member of a cloth material, a leather material or a paper material, and a one-liquid type water-based adhesive using the same.nThe latex mixture of the present invention contains: 100 parts by mass of a chloroprene polymer latex having a pH of 12 or more in terms of a solid content; and 10 to 50 parts by mass of an aqueous dispersion, which is selected from a phenol resin emulsion. And an acrylic latex having a glass transition temperature of -40 to -10 ° C and at least one of an epoxy resin emulsion having a pH of 8.0 to 11.0 and having a carboxyl group. The chloroprene polymer preferably has a gel content of 5 to 30% by mass, a toluene-soluble component having a number average molecular weight of 200,000 to 500,000, and a molecular weight distribution of 2.0 to 4.0. The latex composition can be suitably used as a one-liquid type aqueous adhesive for leather bag use or shoe use. |
