摘要： The purpose of the present invention is to provide a urethane adhesive composition that can suppress a reduction in physical properties of an obtained cured product even if the mixing ratio between a main agent and a curing agent deviates from the design range. The present invention is a two-liquid type urethane adhesive composition comprising a main agent and a curing agent. The main agent comprises a poly isocyanate component, and the isocyanate group content in the main agent is 5 mass% or more of the total amount of the main agent. The curing agent contains a compound having a plurality of active hydrogen-containing groups per molecule, and the compound having a plurality of active hydrogen-containing groups per molecule comprises a high molecular weight polyol having two or three hydroxyl groups per molecule and a number average molecular weight of 1800 or greater, a low molecular weight polyol A having two hydroxyl groups per molecule and a number average molecular weight of 200 or less, and a low molecular weight polyol B having three hydroxyl groups per molecule, with at least one of the three hydroxyl groups being secondary hydroxyl groups, and a number average molecular weight of 1200 or less.

摘要： The present invention addresses the problem of providing a urethane resin composition which contains water, and exhibits excellent oleic acid resistance, low-temperature flexibility, and peeling strength by using biomass raw materials. The present invention provides a urethane resin composition which contains an anionic urethane resin (X) and water (Y), the urethane resin composition being characterized in that the anionic urethane resin (X) includes, as essential raw materials: a polyol (a) which contains a polycarbonate polyol (a1) derived from biomass; a polyisocyanate (b); and an alkanolamine (c). The present invention also provides: an adhesive which is characterized by containing the urethane resin composition; and a synthetic leather which is characterized by having an adhesive layer formed by means of the adhesive.

摘要： A thermoplastic polyurethane resin elastomer is obtained by reacting an isocyanate compound (I), an aliphatic alcohol (II) having only a hydroxyl group as a functional group and having a number average molecular weight determined from the hydroxyl value of less than 300, and a polyol (III) having a number average molecular weight determined from the hydroxyl value of not less than 300 and not more than 10,000. The isocyanate compound (I) comprises not less than 90 mol% in total of an aliphatic isocyanate compound containing two isocyanate groups and/or an alicyclic isocyanate compound containing two isocyanate groups. The aliphatic alcohol (II) comprises not less than 90 mol% of a C12 or lower aliphatic diol. The polyol (III) comprises not less than 80 mol% of a copolymerized polycarbonate diol (IIIA) including a repeating unit (A) illustrated below and a repeating unit (B) illustrated below. The equivalent ratio represented by hydroxyl equivalent (EIII) of polyol (III):isocyanate equivalent (EI) of isocyanate compound (I):hydroxyl equivalent (EII) of aliphatic alcohol (II) is 1:2-6:1-5 (with the proviso that 0.95 ≤ (EI)/( (EII) + (EIII)) ≤ 1.05). The number average molecular weight of the copolymerized polycarbonate diol (IIIA) is not less than 500 and not more than 5,000.
