Title: COATING COMPOSITION CONTAINING METHYL CELLULOSE, METHOD FOR PRODUCING THE SAME, AND SOLID PREPARATION
Abstract: [0001]    Regarding coating of fine particles or the like, provided are a coating composition containing methyl cellulose having small adhesiveness, resistance to generation of lumps, ability to form uniform coating, and ability to form a coating composition easily with water of normal temperature; a method for producing the coating composition; and a solid preparation. More specifically provided are a coating composition comprising methyl cellulose having such a viscosity that a viscosity at 20°C of a 2% by weight aqueous solution of the methyl cellulose is 1 to 15 mPa·s and having such a dissolution start temperature that a dissolution start temperature of a 12% by weight aqueous liquid of the methyl cellulose is 10 to 25°C and a solvent; a solid preparation obtained by coating of the coating composition; and the like.
