摘要： A magenta anthraquinone dyestuff for sublimation thermaltransfer printing is here disclosed. In general, the anthraquinone dyestuff has a strong yellow tone, but in the anthraquinone in which the position of No. 2 is substituted by a phenoxy group, absorption is made on the side of a longer wave length. This kind of dyestuff is characterized by solubility in a solvent, sublimation, adhesion, fastness and the like. The general formula is: A preferred example has R = 3-Me; R = H; R = NH2.

摘要： A material suitable for a guest-host liquid crystal device comprises a solution of a liquid crystal material and a pleochroic dye wherein the pleochroic dye comprises at least one compound having a formula:
wherein one of X and Y is OH and the other is NHR wherein R is H or lower alkyl; each of R 1 and R 2 independently represents alkyl, aryl, aralkyl, alkoxy or -NR 3 R 4 wherein each of R 3 and R 4 is independently H or lower alkyl, provided that R2 is always adjacent to an OH group.
