ABSTRACT:
The present invention provides a new process for recording an image by using the above mentioned phenomenon. The process comprises (i) inserting an anisotropic molecular oriented film between two polarizing film of which polarization directions are parallel or perpendicular to each other, so that the anisotropy of said anisotropic molecular oriented film forms an angle of 45.degree. to the polarization directions of said polarizing film, and (ii) completely or incompletely degrading the anisotropy of an image portion in said anisotropic molecular oriented film.
