COMPOSITION FOR ADHESIVE HYDROGEL AND USE THEREOF

摘要

The purpose of the present invention is to provide a composition for an adhesive hydrogel that shows adhesiveness appropriate for repeated use without requiring a special procedure such as rinsing with water and that has particularly weak skin irritability, and also to provide a use thereof (for instance, an adhesive hydrogel, gel sheet, or electrode). The present invention is a composition for an adhesive hydrogel formed from at least a polymer matrix forming material, water, and a polyvalent alcohol. The polymer matrix forming material is formed from at least: (a) a (meth)acrylic acid, a (meth)acrylic acid derivative, or a C4-5 vinyl derivative having two carboxyl groups; (b) a (meth)acrylamide or (meth)acrylamide derivative; (c) N-vinyl-2-caprolactam and/or N-vinyl-2-valerolactam; and (d) a crosslinkable monomer, wherein the content of (b) in the adhesive hydrogel composition is 2 to 20 wt%.
