Document Type and Number:

WIPO Patent Application WO/2016/143889

Kind Code:

A1

Abstract:

Provided is a laminate film 1 equipped with a base material 2, a polyurethane layer 3 laminated to the base material 2, and a metal vapor deposition layer 4 laminated to the polyurethane layer 3, wherein the polyurethane layer 3 is obtained by applying and drying a coating solution on the base material 2, the coating solution containing a water-dispersible polyisocyanate and a polyurethane dispersion that contains a polyurethane resin obtained by reaction between a chain extender and an isocyanate group-terminated prepolymer obtained by reaction between a polyisocyanate component that contains xylylene diisocyanate and/or hydrogenated xylylene diisocyanate, and a polyol component that contains an active hydrogen group-containing compound having hydrophilic groups, and a C2-6 diol.
