Abstract (en)
[origin: EP0395170A1] A method is provided for developing an essentially permanent and uniform image onto an image member including an optically anisotropic liquid crystalline material, wherein a degrading energy for the liquid crystalline material is selectively applied to a selected portion of the image member to at least partially degrade the liquid crystalline material in that selected portion, thereby altering the optical properties of the liquid crystalline material in that selected portion in comparison with the surrounding liquid crystalline material.
