An advanced reverse treated electrodeposited copper foil and a copper clad laminate using the same are provided. The advanced reverse treated electrodeposited copper foil has an uneven micro-roughened surface. The micro-roughened surface has a plurality of copper crystals, a plurality of copper whiskers and a plurality of copper crystal groups, which are in a non-uniform distribution to form a non-uniformly distributed horizontal or vertical stripe pattern.

To provide a trivalent chromium plating film, in which the generation of cracks penetrating from the film surface to a substrate interface is suppressed, and a sliding member coated with the trivalent chromium plating film, plating is conducted with a chromium plating bath containing trivalent chromium as a chromium source, with a second phase dispersed in a planar and/or fibrous form, such that the second phase in a planar and/or fibrous form is dispersed in the hard chromium plating film to prevent or deflect the propagation of cracks, and to suppress the increase of the crack width, thereby suppressing the propagation of cracks in the hard chromium plating film.
