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 inorganic 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 a 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.
