A novel hetero-polycyclic compound of the following formula, a method for its preparation and its use in the colouration of textile materials:wherein,Z, & Z2 are each independently - 0 -, - S - or - NR5 - in wich R5 is H or an optionally-substituted hydrocarbon group or an acyl group;X1 & X2 are selected from H, halogen, cyano, C1-4-alkyl, C1-4-alkoxy, aryl, carbamoyl, sulphamoyl, carboxylic acid or carboxylic acid ester;R' to R4 are each independently selected from H, C1-4-alkyl, C1-4-alkoxy, C1-4-alkenyl, halogen and the group -X-Y ;X is - 0 - or - S -; andY is a group of the formula:wherein:V & W are each independently H or optionally substituted alkyl;p is an integer from 1 to 3;q is 0 or 1 ;p + q is at least 2; andZ is OR6 or NR6R7 when q = 1; orZ is OR8 or SR8 when q = 0;wherein:R6 is selected from optionally substituted alkyl, optionally substituted alkoxyalkyl and a second group represented by Y in which R6 is optionally substituted alkyl or optionally substituted alkoxyalkyl; andR7 is selected from H, and optionally substituted alkyl;R8 is selected from optionally substituted alkyl, optionally substituted alkoxyalkyl and acyl,provided that, the substituents on rings A & B are different when Z1 & Z2 are the same or that Z1 & Z2 are different when the substituents on rings A & B are the same.
