Composite photographic film for identity cards - has crinkled film which is introduced into photographic emulsion and magnetic track complex

摘要

A composite photographic film is used for identity cards. The film is part of a complex structure which consists of a thin base (6) which protects a magnetic strip (5) or a deposit of magnetic ink. Over this magnetic strip (5) is a light reflecting support which may be made of white plastics. On top of this support is a monochrome or multi chrome print (3). Over this print is placed the crinkled photographic film (2). This film is then covered with a light or heat-sensitive emulsion (1), which can be a black and white, multi chrome, reversible, or negative emulsion.
