US 2017/0321093 A1 · COATING AGENT, DECORATIVE FILM, AND ARTICLE

Abstract

An object of the present invention is to provide a coating agent giving a coating film that has good adhesion and stability over time, a decorative film having at least one layer formed from the coating agent; and an article decorated with the decorative film. The coating agent of the present invention contains, in a specific ratio, an olefin polymer (A) having a heat of fusion of in the range of 0 to 50 J/g and having a weight average molecular weight (Mw) as measured by GPC of 1×104 to 1000×104, a hydrocarbon-based synthetic oil (B) having a 40° C. kinematic viscosity of 30 to 500,000 cSt, and a tackifier (C) having an acid value of 10 or more and having a weight average molecular weight (Mw) of 0.9×103 to 3×103.
