    摘要: A novel benzophenone type polymerizable dye containing a urethane bond and an ophthalmic lens containing the said polymerizable dye are disclosed. The benzophenone type polymerizable dye is shown by the following general formula (1) (wherein R1 and R2 are respectively and independently a hydrogen atom, a hydroxyl group, a carboxylic group, a C1 to C8 alkyl group, a C1 to C8 alkoxy group, a sulfonic acid group or a benzyloxy group, and m and n are respectively and independently an integer of 0 to 18. R3 is any of a polymerizable functional group of a vinyl group, an acryloyl group or a methacryloyl group).

    摘要: Novel yellow azo dye compositions and novel liquid crystal compositions containing the yellow azo dye composition. The yellow azo dye composition, having terminal ester groups, has the general formula: ##STR1## wherein R and R' are alkyl or substituted alkyl wherein the alkyl has at least 4 carbon atoms, aryl, arylalkyl, substituted aryl or substituted arylalkyl. When the yellow azo dichroic dyes are used alone, or in combination with other dyes, as a guest in a host liquid crystal material, they form a novel liquid crystal composition for use in liquid crystal displays. An invention method of improving the black color of dichroic dyes for use in black liquid crystal displays, wherein a dye composition having a mixture of dichroic dyes of various colors and containing at least one yellow azo dichroic dye, as described above, is added to a host liquid crystal material. The mixture of dichroic dyes of various colors must be one which absorbs radiation in the spectral range of about 400-700 nm to produce the substantially black color for use in black liquid crystal displays.
