There is described compositions comprising a solvent and at least one compound of Formula (1) in which: R1 represents H, an optionally substituted C¿1-8? carbyl derived group, or a group of Formula (A) where: c is from 2 to 6; R?3¿ represents optionally substituted C¿1-8? carbyl derived group; R?4 and R5¿ independently represent an optionally substituent; R2 represents an optionally substituted C¿1-8? 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, R2¿, X, Y or Z comprises a group of formula SO¿3?M or PO3M2. These compositions and compounds are useful as the colorants to prepare colour filters for displays. |
