Title:
LAMINATE AND OPTICAL FILM
Document Type and Number:
WIPO Patent Application WO/2015/170560
Kind Code:
A1
Abstract:
The present invention provides a laminate characterized in: having a primer layer formed on the surface of a base material using an aqueous resin composition comprising (A) an aqueous resin with carboxyl groups, (B) an aqueous resin with sulfonic acid groups, and (C) silica; and the surface of the primer layer having a cured coating film formed using an actinic radiation-curable composition. Because this laminate uses an aqueous resin composition with excellent storage stability and coating film transparency as a primer for improving the adhesion between the base material and the cured coating film of the actinic radiation-curable composition, it is possible to form laminates in which a cured coating film of an actinic radiation-curable composition has been formed on the surface of even poorly adhesive base materials such as polyester films and the laminates can be used favorably as optical films.
