MOISTURE CONDITIONING AGENT FOR STORAGE BOX AND STORAGE BOX USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a moisture conditioning agent for a storage box that is excellent in moisture absorbing and releasing rates of moisture, moisture conditioning properties and bedewing resistance and that has air cleaning effect, and to provide a storage box using the same. SOLUTION: The moisture conditioning agent for the storage box is composed of a urethane resin (U) obtained by causing the following water absorption resin dispersion (D) to react with a polyisocynate compound (P) and a material having air cleaning function, and the storage box is characterized by using the same. The water absorption resin dispersion (D): the water absorption resin dispersion having a water absorption resin (B) polymerized in a polyol (A) or a water absorption gel dispersed therein.
