A water-based pressure sensitive adhesive dispersion is provided. The dispersion is a reaction product of a monomer solution and an aqueous phase. The monomer solution contains from about 40 to 70 parts water-insoluble monomer selected from the group consisting of alkyl acrylate, methacrylate, vinyl ester, and combinations thereof and from about 0.01 to 0.2 parts monomer soluble free radical initiator. The aqueous phase includes from about 1 to 20 parts latex binder, from about 0.1 to 2 parts surfactant, from about 0.02 to 1 parts polymeric suspension stabilizer, and water as a remaining balance. All parts are given as parts by weight per 100 parts of the dispersion. The dispersion has a solid phase of at least 60 weight percent, a viscosity of less than about 300 centipoise, measured at about 23°C, and a bimodal particle size distribution.

La présente invention concerne une dispersion adhésive à base d'eau sensible à la pression. La dispersion est un produit de réaction d'une solution de monomère avec une phase aqueuse. La solution de monomère contient d'environ 40 à 70 parties de monomère insoluble dans l'eau choisi dans le groupe constitué par l'acrylate d'alkyle, le méthacrylate, l'ester vinylique et des combinaisons de ceux-ci, et d'environ 0,01 à 0,2 partie d'initiateur de radicaux libres soluble dans le monomère. La phase aqueuse comprend d'environ 1 à 20 parties de liant à base de latex, d'environ 0,1 à 2 parties de tensioactif, d'environ 0,02 à 1 partie de stabilisant de suspension polymère, et de l'eau jusqu'à l'équilibre. Toutes les parties sont données en parties en poids pour 100 parties de la dispersion. La dispersion a une teneur en extrait sec d'au moins 60 pourcent en poids, une viscosité inférieure à environ 300 centipoises, mesurée à environ 23 °C, et une distribution granulométrique bimodale.
