Title:
AQUEOUS RESIN COMPOSITION, LAMINATE USING SAME, OPTICAL FILM, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/123795
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an aqueous resin composition that can be used as a primer that greatly improves adhesion between a substrate and a cured coating of an active energy ray-curable composition, even if the substrate is a poorly-adhesive one such as polyester film. The present invention is an aqueous resin composition containing: a composite resin containing a vinylester resin and a urethane resin having an aromatic ring; an aqueous resin; and an aqueous vehicle. The aqueous resin composition is characterized in that: the vinylester resin is a reaction product of at least one epoxy resin selected from the group consisting of novolac-type epoxy resins and bisphenol-type epoxy resins, and a compound having an acid group and a polymerizable unsaturated group; and the urethane resin is a reaction product of polyols containing a polyol having an aromatic ring and a polyol having a hydrophilic group, and a polyisocyanate.
