摘要：

<；P>；PROBLEM TO BE SOLVED: To replace a resin used for a coating film on a coated granular material containing a bioactive material by an easily degradable resin. <；P>；SOLUTION: The coated granular material is obtained by coating the bioactive material-containing granular material with a urethane resin prepared by reacting an aromatic polyisocyanate, a polyester polyol(preferably polycaprolactone polyol) having &ge；15% (expressed by weight) oxycarbonyl [-O-C(=O)-] partial structure in a molecule and a 4-30C monoalcohol (for example, 1-butanol, 1-hexanol, 1-octanol, 1-dodecanol). <；P>；COPYRIGHT: (C)2008,JPO&INPIT
