Abstract

Official abstract text for this publication.

A living body-adhesive sheet of the present disclosure includes a living body-adhesive film and a support. The living body-adhesive film has a thickness of 5 μm or less and contains cellulose. The support supports the living body-adhesive film. The support is formed of a material in which a hydrogen bonding component δH in a Hansen solubility parameter is 2 to 20 MPa 1/2 .

First claim

Opening claim text (preview).

What is claimed is: 1 . A living body-adhesive sheet comprising: a living body-adhesive film that has a thickness of 5 μm or less and contains cellulose; and a support that supports the living body-adhesive film, wherein the support is formed of a material in which a hydrogen bonding component δH in a Hansen solubility parameter is 2 to 20 MPa 1/2 . 2 . The living body-adhesive sheet according to claim 1 , wherein the support includes protrusions and recesses that are covered with the living body-adhesive film. 3 . The living body-adhesive sheet according to claim 2 , wherein the support is a non-woven fabric. 4 . The living body-adhesive sheet according to claim 1 , wherein the support has a weight of 20 to 70 g/m 2 . 5 . The living body-adhesive sheet according to claim 1 , wherein the cellulose is regenerated cellulose having a weight-average molecular weight of 30,000 or more. 6 . The living body-adhesive sheet according to claim 1 , wherein the living body-adhesive film is a self-supporting film having a thickness of 20 to 1300 nm. 7 . The living body-adhesive sheet according claim 1 , wherein the support is formed of at least one material selected from the group consisting of polyethylene, polyethylene terephthalate, polyacrylonitrile, polystyrene, polyvinyl chloride, polycarbonate, and polyethyleneimide.
