Abstract: An adhesive for an electrical storage device packaging material containing a polyol compound (A), a polyisocyanate compound (B), and an epoxy resin (C), in which the polyol compound (A) contains an ester bond-containing polyol, and the following formula is satisfied when a stress at the time when a cured film obtained by performing curing under the condition of 80° C. for 2 weeks is stretched to twice its length at a speed of 6 mm/min under an environment of 20° C. and 65% RH is S1 [N/mm2], and a stress at the time when the cured film is held for 100 seconds in a stretched state is S2 [N/mm2]. Formula: 10.0?(S1?S2)/S1×100?40.0.

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.

Abstract: Provided is an adhesive giving a laminate for packaging that favorably withstands retort processing even when the period for curing reaction (aging period) is shortened. The adhesive conysind: a partially acid-modified polyester alcohol composition (A), prepared by esterifying a part of the hydroxyl groups in a polyester alcohol composition produced by condensation of a polyvalent alcohol and a polyvalent alcohol containing at least one of a monocarboxylic acid and a monovalent alcohol, with anhydrotrimellitic acid and a anhydrotrimellitate ester at an anhydrotrimellitic acid/anhydrotrimellitate ester ratio of 10/90 to 70/30 (by mass); and a polyisocyanate (B). Also provided is a laminate for packaging of a plurality of sheet-shaped base materials bonded to each other with the adhesive.

Abstract: Disclosed is an adhesive and a packaging laminate produced by using the same. The adhesive contains a polyisocyanate and a partially acid-modified polyol which is a product of reacting a polyol with anhydrotrimellitic acid and an anhydrotrimellitate ester at a ratio such that the anhydrotrimellitic acid is 10 to 70% by mass and the anhydrotrimellitate ester is 90 to 30% by mass, as the sum of the anhydrotrimellitic acid and the anhydrotrimellitate ester is 100% by mass. The packaging laminate has a first and second sheet-shaped substrates and the above adhesive through which the first and second sheet-shaped substrates are laminated.
