Document Type and Number:

WIPO Patent Application WO/2011/122238

Kind Code:

A1

Abstract:

Provided is a coated granular body, which comprises a granular water-soluble substance; a coating layer that is formed on the granular water-soluble substance and that has a thermosetting resin A comprising a resin solution having a molar ratio A of isocyanate groups and hydroxyl groups of 0.5 to 0.99; and a protective layer that is formed on the coating layer and has a thermosetting resin B comprising a resin solution having a molar ratio B of isocyanate groups and hydroxyl groups of 0.75 to 2.0. The molar ratio B of the protective layer is greater than the molar ratio A of the coating layer. By means of the coated granular body, it is possible to simultaneously realize a short-term dissolution-type dissolution pattern and to control initial dissolution while maintaining good quality.
