Abstract: This can for an effervescent beverage includes an upper surface, a lower surface, and a middle part. On the inner surface of the middle part, a plurality of first recesses is formed, each having a diameter of at least 5 ?m. The number of the plurality of first recesses is 200 to 2,000 per 1 mm2.

Abstract: Processability of a paint film is improved and a water-soluble paint in which coloring during heating to a high temperature is minimized and which has excellent productivity and a coated can having a paint film of such a water-soluble paint are provided. A water-soluble paint including a polymer emulsion (C) and a phenolic resin (D) is provided; wherein the polymer emulsion (C) includes a shell part containing an acrylic polymer (A) having a carboxyl group and a core part containing an acrylic polymer (B) having an amide group, wherein the phenolic resin (D) includes a bifunctional phenolic resin (D2) based on a bifunctional phenol and a trifunctional phenolic resin (D3) based on a trifunctional phenol, and a mass ratio ((D2)/(D3)) between the bifunctional phenolic resin (D2) and the trifunctional phenolic resin (D3) is 95/5 to 40/60.

Abstract: An adhesive composition that exhibits excellent adhesive performance such as curved surface adhesiveness to low-polarity adherends and constant load peeling properties in high-temperature environments, and also an adhesive sheet and a method for producing the same.

Abstract: Provided is an adhesive which, in a metal foil-containing laminated composite film used in a high temperature sterilization treatment, is resistant to the effects of moisture in the air during curing, has good workability when used as a solvent-free adhesive, and exhibits excellent adhesive strength and acid resistance. Provided is a method for producing an adhesive composition, the method including: a step of obtaining an alcohol-added isocyanate (E) by reacting a trifunctional or higher isocyanate compound (C2) and a monofunctional alcohol (D) at an equivalence ratio of isocyanate groups in the trifunctional or higher isocyanate compound (C2):monofunctional alcohol (D)=100 mol %:25 to 65 mol %, and a step of mixing a polyisocyanate (A) containing a trifunctional or higher isocyanate compound (C1) and the alcohol-added isocyanate (E), and an alcohol (B) having an acid value of 0.
