The present invention provides a titanium compound sol solution capable of enabling manufacturing of a film high in transparency and having an excellent photocatalyst effect by low-temperature processing, and a coating film using the same. The present invention is a titanium compound sol solution containing a particulate incomplete condensate obtained by condensing an alkoxy titanium, an &#x3b1;-substituted &#x3b2;-diketone, and a solvent.

Titanium compound sol solution, coating film using the same and manufacturing method thereof

This invention provides a process for producing a conductive rubber roller having small aspect ratios of inner and outer diameters, having a stable measure of its inner diameter, having uniform cell distribution and being free from non-uniformity of hardness and electrical resistance in the peripheral direction. The process has a step of continuously extruding a tube composed of a specific unvulcanized rubber composition from a rubber extruder in a microwave vulcanizing unit, and a step of foaming and vulcanizing the tube by using a microwave irradiator having a microwave irradiation zone 4 m or less in length while being transported at given speed. The foamed rubber tube has an inner diameter 20 to 35% smaller than the outer diameter of the conductive core material over the whole region in the lengthwise direction, and the conductive core material is press-fitted into the foamed rubber tube without using any adhesive.
