摘要： 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: (A) a water-soluble resin obtained by neutralizing a resin having an acid value of 1 meq/g or more, with a base, and (B) a polymer having an acid value of 0.6 meq/g or less and a glass transition temperature of −20° 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° 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° 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).

摘要： A process for producing a pressure-sensitive adhesive sheet using an aqueous resin emulsion is disclosed. The aqueous resin emulsion is an aqueous resin emulsion that dispersed particles have a weight average particle diameter of 0.3 .mu.m or smaller and a ratio of the weight average particle diameter thereof to an arithmetic average particle diameter thereof [(weight average particle diameter)/(arithmetic average particle diameter)] is 1.0 to 1.5. The resin contained in the aqueous resin emulsion preferably comprises an alkyl (meth)acrylate monomer unit (a) having 4 to 12 carbon atoms in the alkyl moiety, an .alpha.,.beta.-ethylenically unsaturated carboxylic acid monomer unit (b), and a radically polymerizable monomer unit (c) having a cyclic structure, other than the monomer units (a) and (b), the proportions of the monomer unit (a), the monomer unit (b), and the monomer unit (c) being 45 to 97% by weight, 0.1 to 10% by weight, and 2.9 to 30% by weight, respectively, with the total amount of those units being 100% by weight. The aqueous resin emulsion preferably contains a nonionic surfactant. The pressure-sensitive adhesive sheet obtained by the process has a property such that the pressure-sensitive adhesive layer thereof is less apt to blush even upon contact with water by immersion in water, moisture absorption, etc.
