MONOAZO DYESTUFFS USEFUL FOR COLOUR FILTERS AND INK JET PRINTING

摘要

There is described compositions comprising a solvent and at least one compound of Formula (1) in which: R<1> represents H, an optionally substituted C1-8 carbyl derived group, or a group of Formula (A) where: c is from 2 to 6; R<3> represents optionally substituted C1-8 carbyl derived group; R<4> and R<5> independently represent an optionally substituent; R<2> represents an optionally substituted C1-8 carbyl derived group; X, Y and Z independently represent H or an optional substituent; M represents H or a cation; m and n independently represent 0, 1 or 2. Also compounds as in Formula (1) providing that at least one of R<1>, R<2>, X, Y or Z comprises a group of formula SO3M or PO3M2. These compositions and compounds are useful as the colorants to prepare colour filters for displays.
