Abstract
A process for producing an article with a label, which comprises attaching, to an article, a heat-sensitive and pressure-sensitive adhesive label having an adhesive layer composed of a pressure-sensitive adhesive composition, which is an aqueous emulsion type composition comprising: PA1 (A) a water-soluble resin obtained by neutralizing a resin having an acid value of 1 meq/g or more, with a base, and PA1 (B) a polymer having an acid value of 0.6 meq/g or less and a glass transition temperature of -20.degree. C. or lower, obtained by emulsion polymerization of a radical-polymerizable monomer, and which, when made into an aqueous film and dried at a temperature lower than 60.degree. C., becomes a film (1) of two-phase structure wherein particles composed of the component (B) are dispersed in a continuous phase composed of the component (A) and, when the film (1) is heated to a temperature of 60.degree. C. or higher, is converted into a pressure-sensitive adhesive film (2) wherein the forms of the component (A) and the component (B) in the above two-phase structure are reversed and particles of the component (A) are dispersed in a continuous phase of the component (B).
