ABSTRACT:
A reprographic imaging method based upon a color modifying reaction. In one embodiment of this method a leuco (colorless or weakly colored) form of a material is allowed to selectively react with an appropriate reagent across a divider in response to selective photochemical modification of said divider whereby the leuco form of this material is converted to a highly colored derivative. In a second embodiment of this invention, the reverse occurs; namely a highly colored material is converted to a colorless or weakly colored derivative. A third contemplated embodiment of this invention involves the conversion of a one colored material to another accompanied by a substituted shift in its absorption spectrum. Each of these systems are highly suitable in preparation of transparencies such as microfilm recordings.
