Liquid crystalline filter dyes for imaging elements

摘要

This invention is a dispersion comprising a solvent having dispersed therein a liquid-crystal forming dye of structural Formula I: ÄD-(X)mÜ-(Y)n wherein: D is a merocyanine dye; each Y contains an ionic or a nonionic solubilizing substituent or a group with a pKa value of less than 4 in water; each X is a nonionic substituent; n is I to 10; m is 0-10; and the resulting dye forms a liquid-crystalline phase in solvent. The dispersion is particularly useful in imaging and photographic elements.
