ABSTRACT:
The present invention relates to a composite film. More particularly, the present invention relates to a composite compound film and composite compound multilayered film, comprising a metal, an alloy and/or an inorganic substance with an organic substance, which is excellent in decorative properties, protection and functionality. Methods applicable for forming such a composite compound film include the technique of evaporating a metal, an alloy, and/or an organic substance and an organic substance, simultaneously exciting the evaporated particles, and causing vapor-deposition in the state of ionized particles, neutral particles or radicals, and a method of sputtering, without excitation, etc. Further, a composite compound film which contains an organic substance can have an excellent color tone, and at the same time, reduces the amounts of high cost metals, alloys, or inorganic substances and provides a frictional coefficient lower than that of a film formed from a metal, an alloy or an inorganic substance alone. The film has a wear resistance which can be improved over that of a film comprising only the material of the composite film.
