COATING AGENT COMPOSITION AND USE THEREOF

摘要

A coating agent composition comprising an isocyanate-having prepolymer obtained by reacting a polyol containing a polyoxyalkylenepolyol of 2 to 4 average hydroxyl quantity, 85 to 100 mass% oxyethylene group content based on all oxyalkylene groups (100 mass%) and 800 to 2500 arithmetic average molecular weight with an alicyclic isocyanate and/or aliphatic isocyanate amounting to an isocyanate index of 150 to 300 in the presence of a catalyst of organic acid bismuth salt. Thus, there can be provided a coating agent composition capable of forming a film or coating that has moisture permeability, excelling in mechanical properties and yellowing resistance, and that has wash durability and resistance to sweat deterioration, containing no organotin compounds.
