摘要： An aqueous polyhydroxyurethane resin dispersion, which can be stored for a long time, and with which a coating film having a high gas-barrier property can be formed; an aqueous dispersion composition containing a complex of the resin and a clay mineral; and a film having a high gas-barrier property produced using the aqueous polyhydroxyurethane resin dispersion or the aqueous dispersion composition are provided. The aqueous polyhydroxyurethane resin dispersion comprises a polyhydroxyurethane resin finely dispersed in water, where the polyhydroxyurethane resin has in its structure, a repeating unit represented by formula (1) as a basic structure and a carboxyl group-containing chemical structure moiety represented by formula (6), described in this specification. The aqueous dispersion composition comprising the polyhydroxyurethane resin and a layered clay mineral form composite. The film having a high gas-barrier is produced using the aqueous dispersion or the aqueous dispersion composition.

摘要： The present invention provides a resin composition for an adhesive, being useful as a component of an adhesive having a favorable adhesion property to glass and giving favorable appearance after adhesion. The resin composition for an adhesive contains a polyhydroxyurethane resin. This polyhydroxyurethane resin contains a structural unit formed by polymerizing a compound (A) having at least two five-membered cyclic carbonate structures and a compound (B) having at least two primary amino groups, the polyurethane resin contains a urethane bond, a hydroxy group, and a secondary amino group in the structural unit. Further, this polyhydroxyurethane resin has an amine number of 1 to 50 mgKOH/g and has a hydroxyl number of 10 to 230 mgKOH/g.
