ABSTRACT:
The ion distribution in a high molecular film is controlled by selectively altering the ion pattern under a combination of heat and electric field where at least one of the latter is applied to the film in the desired pattern. Selectively altering the ion pattern is accomplished by any one of the following: lateral shifting of ions in one film, removal of ions from one film and concurrent injection into a second film; removal of ion disassociative molecules from one film and concurrent injection into a second film. Ions which color the film are preferably used to permit visual inspection of the ion pattern. The film with the ion pattern is particularly adapted for electro-photographic copying.
