Abstract
1357974 Photo-electrophoretic composition; photo-electrophoresis CIBA-GEIGY AG 16 Dec 1971 [16 Dec 1970] 58462/71 Headings G2C and G2H A photo-electrophoretic composition comprises at least one electrically photo-sensitive pigment of formula or 4, 4′-diamino-1, 1′-dianthraquinonyl wherein R is an arylene radical, X and Y are hydrogen, halogen, alkyl or alkoxy or X and Y together with two adjacent C atoms for a benzene ring, X 1 and Y 1 are hydrogen, halogen, alkoxy, carbonamide or nitro and R 1 is a benzene ring. In the specific embodiments R is dimethyl phenylene, methylchlorophenylene, methoxyphenylene, mono or di chlorophenylene or fluoranthenylene, X and Y are methyl or chloro and R 1 is phenyl. The pigment may be suspended in a saturated aliphatic hydrocarbon together with a resin. Mono or poly chromatic compositions may be used.
