Title:
WATER-ABSORBING SHEET
Document Type and Number:
WIPO Patent Application WO/2018/034116
Kind Code:
A1
Abstract:
A water-absorbing sheet has a water-containing photocuring film of a water-containing acrylic monomer film that contains a water-soluble acrylic monomer component and water. The water-soluble acrylic monomer component exhibits transparency when mixed with 18 mass% or more of water at 23°C. More specifically, transparency with a haze of 8% or less. It is preferable that all of the water-soluble acrylic monomers that constitute part of the water-soluble acrylic monomer component exhibit transparency even when mixed with 18 mass% or more of water at 23°C. Examples of such water-soluble acrylic monomers include hydroxy-group-containing acrylic monomers, and in particular, 4-hydroxybutyl acrylate, 2-hydroxypropyl acrylate, or 2-hydroxyethyl methacrylate.
