摘要： This invention is a dispersion comprising a solvent having dispersed therein a liquid-crystal forming dye of structural Formula I:

[D-(X) m ]-(Y) n I

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.
