Abstract: To provide a peroral tablet for bowel cleansing which leaves no remains in the intestinal tract after bowel cleansing, which exhibits a dissolution property equivalent to that of conventional sodium phosphate-containing tablets including crystalline cellulose, and which is a small-size agent readily taken by a subject. The peroral tablet for bowel cleansing containing the following ingredients (A) and (B): (A) 80 to 95 mass % of sodium phosphate, and (B) (B1) 7 to 11 mass % of hydroxypropyl cellulose which has such a particle size that ?99% of the particles thereof pass through a mesh having an opening of 350 ?m and whose 2-mass % aqueous solution has a viscosity of 2.0 to 10.0 mPa.s, (B2) 5 to 13 mass % of hydroxypropyl cellulose which has such a particle size that ?99% of the particles thereof pass through a mesh having an opening of 150 ?m and whose 2-mass % aqueous solution has a viscosity of 3.0 to 5.9 mPa.

Abstract: Disclosed herein is an information recording medium which is composed of a substrate, underlayer, and recording film and is capable of recording information by means of depressions or pits which are formed on the recording film upon irradiation with a recording energy beam, said information recording medium being characterized in that the recording film is provided with a supporting layer on at least one side of the recording film, said supporting layer having a melting point which is lower than that of the recording film, or on that side of the recording film which is adjacent to the substrate, said supporting layer having a melting point which is higher than that of the recording film. Owing to these features, the information recording medium gives recording pits having a smaller rim inner diameter, so that it achieves a high recording power margin for high-density recording.
