    Abstract: Novel liquid crystalline compositions containing an advantageous aligning agent resin, which causes said compositions, upon application to any suitable substrate to spontaneously align or to have a greater tendency to become aligned in an orientation wherein major axes of the molecules comprising liquid crystalline material are substantially perpendicular to the plane of the subtrate. Such liquid crystalline compositions are particularly suited for use in phase transition systems wherein a film comprising cholesteric liquid crystalline material having the tendency to align is transformed to the nematic liquid crystalline state by the application of electrical fields of sufficient field strengths. Such compositions are also used in other liquid crystalline imaging systems making use of differently aligned portions of liquid crystalline films.

    Abstract: An imaging system which utilizes an imaging member comprising a layer of an imaging composition which exhibits the optical properties of the cholesteric liquid crystalline mesophase is disclosed. The imaging member is provided in a light scattering state, imagewise heated above the isotropic transition temperature and allowed to return to a temperature within the mesomorphic temperature range thus resulting in a visible image which typically remains for extended periods of time. The images can be erased and the imaging members reused.
