FUNCTIONAL MICROPARTICLES AND RESIN PRODUCT CONTAINING SAME

摘要

[Problem] Many of the conventional deodorants have a problem of not exhibiting sufficient deodorization effect on some kinds of odors, particularly, not exhibiting satisfactory deodorization effect on complex odors such as a sweat odor or a body odor associated with aging, though the conventional deodorants exhibit excellent deodorization effect on specific kinds of odors. When added to a resin or the like, the conventional deodorants also cause a problem of deteriorating the wear resistance or other performance of the resin. In order to solve such problems of the prior art, the present invention provides moisture-absorbing deodorizing microparticles which when added to a resin, do not significantly deteriorate the wear resistance of the resin and which can impart not only high deodorization performance against basic and acidic odors but also moisture-absorption performance to the resin. [Solution] Functional microparticles which comprise moisture-absorbing and -desorbing microparticles that have crosslinked structure and that contain salt-type carboxyl groups in an amount of 1.8mmol/g or more and at least 0.05wt% of a basic polymer adhering to the moisture-absorbing and -desorbing microparticles and which have a mean particle diameter of 0.01 to 200μm.
