Stabilization of color images formed by photomodulation of the Christiansen effect

摘要

A method of stabilizing a color image resulting from the photomodulation of a Christiansen cell is provided by adding a cross-linking monomer to an optically homogeneous, photopolymerizable medium of a Christiansen cell in an amount sufficient to produce cross-linked polymer upon exposure to actinic light which stabilizes the color image formed and maintains the optical homogeneity of the medium. An improved color image can be formed by also adding to the medium a small amount of a nitroso dimer.
