摘要： A black recording liquid suitable for use in ink-jet recording or as an ink for writing instruments comprises at feast two water-soluble dyes and a liquid medium. Each of the dyes satisfies the condition defined by the following expression (I), and a mixture of these dyes satisfies the condition defined by the following expression (II).

In these expressions, a* and b* are chromaticness indices defined in the CIE 1976 (L * , a * , b*) space, iindicates the ith dye of the dyes used together, and n is an integer of 2 or more.

摘要： A liquid crystal composition of the guest-host type contains a pleochroic dye dissolved therein. The dye molecule has an end group or end groups in the molecule represented by the general formula:
wherein Ro designates a straight chain alkyl group, in which methylene groups not adjacent to the nitrogen atom may be substituted by oxygen atom or sulfur atom; R1 designates an alkyl group having a chain length different from the alkyl group of Ro or a group
in R1 a methylene group not adjacent of the nitrogen atom may be substituted by an oxygen atom or sulfur atom, and R2 designates a hydrogen atom, an alkyl group, alkoxy group, cycloalkyl group or dialkylamino group.
