The present invention provides a thermosensitive recording medium with excellent color developing sensitivity, moist heat resistance and plasticizer resistance, as well as excellent heat resistance, background coloring, light resistance and the like in the printed image.A diphenyl sulfone derivative containing a hydroxyl group on one end and an alkoxy group on the other end has a higher melting point than the one containing hydroxyl groups on both ends. As a result, the thermosensitive recording medium obtained using the diphenyl sulfone derivative as the color developing agent in the thermosensitive color developing layer has excellent heat resistance. However the color developing sensitivity of the thermosensitive recording medium generally declines simultaneously, when a color developing agent with a high melting point is ordinarily used. The thermosensitive recording medium of the present invention that uses a combination of the diphenyl sulfone derivative and a specific phenol derivative in the thermosensitive color developing layer has a good color developing sensitivity and an improved balance among the properties such as moist heat resistance, plasticizer resistance and the like.

A wear of an electrode is prevented as much as possible, thereby efficiently electrolyzing a sulfuric acid solution and the like. An electrolysis method includes: passing an electrolytic solution through an electrolysis cell including at least a pair of an anode and a cathode; and supplying the electrodes with an electric power, so as to electrolyze the electrolytic solution, wherein a viscosity of the electrolytic solution is set in a range in response to a current density upon the electric power supply to carry out the electrolysis. The viscosity of a sulfuric acid solution as the electrolytic solution is equal to or less than 10 cP when the current density is equal to or less than 50 A/dm2, the viscosity of the sulfuric acid solution is equal to or less than 8 cP when the current density is from more than 50 to 75 A/dm2, and the viscosity of the sulfuric acid solution is equal to or less than 6 cP when the current density is from more than 75 to 100 A/dm2. Particularly when a highly-concentrated sulfuric acid solution is electrolyzed at a high current density using diamond electrodes, the electrolysis process can be carried out highly efficiently while a wear of the electrode is reduced.

If incorporated in a cleaning system using persulfuric acid, the invention serves for continuous cleaning while increasing the persulfuric acid concentration adequately to ensure enhanced cleaning performance. The invention provides a feeding apparatus that feeds persulfuric acid to a cleaning apparatus. The cleaning system uses an electrolysis reactor 10 that regenerates the persulfuric acid solution by performing electrolytic reaction to produce persulfate ions from sulfate ions contained in the solution, and a circulation line 4, 5, 6 that circulates the persulfuric acid solution between the cleaning vessel 1 and the electrolysis reactor 10. Configured as above, the invention can provides a feeding apparatus. The cleaning system comprises said configuration and a cleaning vessel 1 that cleans objects 30 using a persulfuric acid solution 2 as cleaning fluid.
