ABSTRACT:
The subject is a carbon film, which consists of a transparent plastic film as base, a coloring, dark pigmented carbon layer, and a thin intervening layer located between the base and the carbon layer. Such a carbon film can be used as "carbon paper" or for the production of typewriter ribbons. The intervening layer contains synthetic lustrous pigments, color-doped as necessary, whereby the back of the film acquires an excellent coloring, without requiring a special covering layer for it.
