摘要： The invention relates to a coating composition for preparing a back coating film of a mirror. The mirror has a glass substrate, a silver mirror film formed on a back surface of the glass substrate, a metallic protective film formed on the silver mirror film, and the back coating film formed on the metallic protective film. The coating composition comprises: a binder consisting of 40 to 85 parts by weight of the total of an epoxy resin and a hardener of the epoxy resin, and 15 to 60 parts by weight of at least one selected from the group consisting of a ketone formaldehyde resin and its derivatives; and a pigment blend containing 7-55 wt % of a corrosion-inhibitive pigment based on the weight of the pigment blend. The weight ratio of the pigment blend to the binder is in the range from 1.2 to 4.0. The back coating film is superior in chemical resistance and corrosion resistance even if a lead-free corrosion-inhibitive pigment is used.

摘要： A rolling contact bearing includes an inner race (1), an outer race (2) accommodating therein the inner race (1), and a plurality of rolling elements (4) interposed between the inner and outer races (1, 2). An insulating covering (8) made of an elastic material having an electric insulating property is mounted around the outer race (2). This insulating covering (8) includes a cylindrical body (8a) and collars (8b) extending radially inwardly from opposite ends of the cylindrical body (8a). This cylindrical body (8a) in a natural condition has an inner diameter smaller than an outer diameter of the outer race (2), but in an assembled condition with the insulating covering (8) placed around the outer race (2) against its own elasticity, the cylindrical body (8a) is held in tight contact with an outer peripheral surface (2a) of the outer race (2) and the collars (8b) are held in tight contact with respective opposite end faces (2b) of the outer race (2).
