PULP-LIKE HYGROSCOPIC MATERIAL AND CONDITIONED PAPER

摘要

PROBLEM TO BE SOLVED: To provide a pulp-like hygroscopic material free from falling-off and deviation of a hygroscopic component, having a rapid-reversible, moisture controlling property, heat stability, and excellent dimensional stability, and to provide a conditioned paper and a highly decorative colored conditioned paper comprising the same. SOLUTION: The pulpy hygroscopic material is a composite material comprising glass microparticles and polyamide, wherein the particle diameter of the glass microparticle is at most 300 nm, and the content of the glass microparticles is 30-80 mass%. The conditioned paper comprises the pulpy hygroscopic material.
