ABSTRACT:
A photorecording element consists essentially of a transparent substrate, a layer of a macromolecular compound capable of undergoing a reversible change in structure upon exposure to light, deposited by adsorption on the transparent substrate, and a liquid crystal layer disposed directly on the layer of macromolecular compound. A method for the production of the photorecording element comprises applying on a transparent substrate a mixture of a liquid crystal substance with a macromolecular compound capable of undergoing a reversible change in structure upon exposure to light and allowing the applied layer of the mixture to stand at rest or by first applying the macromolecular compound on the transparent substrate and then adding the liquid crystal substance thereto. A liquid crystal cell incorporating the photorecording element is also disclosed.
