Title:
ADHESIVE COMPOSITION FOR DECORATIVE FILM
Document Type and Number:
WIPO Patent Application WO/2021/049480
Kind Code:
A1
Abstract:
One embodiment of the present invention relates to an adhesive composition for a decorative film, the decorative film, or a decorative molded body. The adhesive composition for a decorative film includes a (meth)acrylic polymer (A) that satisfies the following conditions (I) and (II), has a weight-average molecular weight of 300,000 or less as measured using a GPC method, and has a glass transition temperature of greater than 0°C and less than 50°C as obtained from the peak temperature of the tanδ measured using a dynamic viscoelasticity measurement method, wherein in relation to the total 100 mass% of the polymer (A) and a (meth)acrylic polymer (Ah) having a glass transition temperature greater than or equal to 50°C, the polymer (Ah) content is less than 25 mass%. (I) The polymer (A) is a polymer of a monomer component including 19 mass% or more of a monomer (a1) that does not have a crosslinking functional group.
(II) A homopolymer of the monomer (a1) has a glass transition temperature greater than or equal to 0°C.
