WIPO Patent Application WO/2024/071274
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a surface modification composition which enables a surface treatment to be performed simultaneously with molding of a resin member, and which is capable of forming a surface modification layer that has high adhesion and excellent coverage, while being suppressed in covering variation. The present invention relates to a surface modification composition containing a polymer component, wherein the loss tangent (tanδ) of a surface modification layer that is formed of this surface modification composition is 1.06 or less at 145°C as determined by dynamic viscoelasticity measurement, and the number average molecular weight of the polymer component is 20,000 or more.
