Abstract
An aliphatically unsaturated organic compound is hydrogenated to form a saturated compound and a salt of the saturated compound is reacted with a halogen and a halide to form a light-polarizing material. The light-polarizing material in the form of crystalline particles is dispersed in a suitable suspending medium to produce a fluid suspension thereof. The suspension is useful in light valves.
