Abstract: Easily water-dispersible pulverulent formulations of disperse dyes are prepared by spray-drying a dye solution which comprises (a) one or more disperse dyes, (b) one or more water-soluble anionic dispersants, (c) from 0 to 20% by weight, based on (a+b+c+d), of other surfactants and (d) from 0 to 20% by weight, based on (a+b+c+d) of agents which serve as protective colloids (the proportion of (c+d) being at most 20% by weight). Suitable solvents (e) are formic acid, formamide, N-methylformamide, butyrolactone, ethylene glycol and propylene glycol, which may in addition contain up to 100% by weight, based on (e), of N,N-dimethylformamide or acetic acid or mixtures of these. The formulations obtained by the above process contain the dye in very fine dispersion.

Abstract: Finely divided, pulverulent carotinoid or retinoid compositions, in which the carotinoid or retinoid essentially has a particle size of less than 0.5 micron, are prepared by a process wherein a carotinoid or retinoid is dissolved in a volatile, water-miscible, organic solvent at from 50 DEG C. to 200 DEG C., if necessary under superatmospheric pressure, within the space of less than 10 seconds. The carotinoid is immediately precipitated, in a colloidally disperse form, from the molecularly disperse solution by rapidly mixing the latter with an aqueous solution of a swellable colloid at from 0 DEG C. to 50 DEG C., and the resulting dispersion is freed from the solvent and the dispersing medium in a conventional manner.

Abstract: The invention relates to the use of dyes of the formula I in which R is a heterocyclic radical and X is nitro, amino, substituted amino, mercapto or hydroxyl, in electro-optical displays containing liquid crystals, and to liquid-crystal mixtures containing dyes of the formula in Claim 1.
