摘要： 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 0.5 to 30 mgKOH/g, so that the equivalence ratio between isocyanate groups in the polyisocyanate (A) and hydroxyl groups in the alcohol (B) (isocyanate groups/hydroxyl groups) is within a range from 0.7 to 2.5.

摘要： The present invention relates to an alcohol-based printing ink composition, comprising a colorant (E), a medium and a polyurethane urea resin (D) obtained by reacting a polyol (A), a diisocyanate (B) and a chain extender (C), wherein the polyol (A) comprises a polyester polyol (A0) having a repeating unit derived from a saturated hydroxycarboxylic acid having a side chain, and the medium comprises an alcohol (F), wherein the proportion of the alcohol (F) is at least 50% by weight relative to a value of 100% by weight for the total medium. Accordingly, the invention provides a printing ink comprising an alcohol having minimal environmental impact as the main component of the ink medium, the ink exhibiting excellent colorant dispersibility and storage stability, and having excellent re-solubility during long runs.

摘要： The invention provides a pressure-sensitive adhesive composition, which is prepared by using an alcohol solvent to obtain a high-molecular weight acrylic polymer, and exhibits excellent levels of coating liquid storage stability, stability over time in the adhesiveness, aging suitability, adhesive strength, releasability and heat-resistant holding power, as well as providing a pressure-sensitive adhesive sheet. The pressure-sensitive adhesive composition comprises a specific crosslinking agent and an acrylic polymer with a glass transition temperature of −60 to 0° C. obtained by radical polymerization in an alcohol solvent of an ethylenic unsaturated bond-containing monomer comprising specific amounts of specific monomers, wherein the acrylic polymer contains a low-molecular weight component and a high-molecular weight component with an area ratio therebetween of 65/35 to 80/20, and the monomer has a carboxyl group.
