    Abstract: The blocked isocyanate is a blocked isocyanate containing a latent isocyanate group, which is an isocyanate group blocked with a blocking agent, wherein the blocked isocyanate includes a first latent isocyanate group that is an isocyanate group blocked with a first blocking agent and a second latent isocyanate group that is an isocyanate group blocked with a second blocking agent; and the first blocking agent is represented by general formula (1) below, and has a higher catalysis activity that activates the isocyanate group than that of the second blocking agent. (where R1 to R3 represent a hydrocarbon group having 1 to 12 carbon atoms or a hydrogen atom, and at least one of R1 to R3 represents a hydrogen atom, and R1 and R3 may be bonded to each other to form a heterocycle. R4 represents a hydrocarbon group having 1 to 12 carbon atoms, a hydrogen atom, or an atomic group represented by —NR5R6 (R5 and R6 represent a hydrocarbon group having 1 to 12 carbon atoms, and R5 and R1 may be bonded to each other to form a heterocycle and R6 and R3 may be bonded to each other to form a heterocycle).

    Abstract: A polyurethane dispersion is a polyurethane dispersion in which polyurethane resin produced by reaction of an isocyanate group-terminated prepolymer with a chain extender is dispersed in water. The isocyanate group-terminated prepolymer is produced by at least allowing a polyisocyanate component containing xylylene diisocyanate and/or hydrogenated xylylene diisocyanate to react with a polyol component containing diol having 2 to 6 carbon atoms, a low-molecular-weight polyol having a functionality of three or more, and an active hydrogen group-containing compound containing a hydrophilic group. The chain extender contains an alkoxysilyl compound having a primary amino group, or a primary amino group and a secondary amino group, and the molar ratio of the hydroxyl group in the low-molecular-weight polyol having a functionality of three or more is less than 25% relative to a total mol 100% of the hydroxyl group in the polyol component.

    Abstract: In a laminate film 1 including a substrate 2, a polyurethane layer 3 formed on the substrate 2, and a metal vapor deposition layer 4 formed on the polyurethane layer 3, a coating liquid is applied on the substrate 2 and dried to produce the polyurethane layer 3. The coating liquid contains a water dispersible polyisocyanate and a polyurethane dispersion containing polyurethane resin produced by reaction of an isocyanate group-terminated prepolymer with a chain extender. The isocyanate group-terminated prepolymer is produced by reaction of a polyisocyanate component including xylylene diisocyanate and/or hydrogenated xylylene diisocyanate and a polyol component including diol having 2 to 6 carbon atoms and an active hydrogen group-containing compound containing a hydrophilic group.
