SHEET-LIKE MATERIAL AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a sheet-like material and a method of manufacturing the same which can be handled excellently, generates no agglomeration of polymer microparticles in a coating liquid, causes no tack between the sheet-like materials when piled up and of which no polymer microparticle peels off. SOLUTION: A polymer microparticle dispersion obtained by adding an inorganic electrolyte to a microparticle dispersion of a copolymer which has an ethylenically unsaturated monomer having a nonionic hydrophilic group and an ethylenically unsaturated hydrophobic monomer is applied onto a supporting member and dried to obtain the sheet-like material.
