| titleOfInvention | Preparation of polycyclic dyes |
| abstract | A process for the preparation of a polycyclic dye of Formula (1): ##STR1## by reacting a compound of Formula (2): ##STR2## with a benzofuranone of the Formula (3): ##STR3## wherein: Ring A is unsubstituted or is substituted by from one to three groups; n Ring B is unsubstituted, apart from the nitro group, or is substituted by one or two further groups; n R is H, optionally substituted alkyl or optionally substituted aryl; and n Z is an oxyammonium group, and certain novel compounds of Formula (2) are disclosed. n The process provides a convenient route to polycyclic dyes which are useful for the coloration of synthetic textile materials particularly polyesters. |
