<p>New condensed heterocycles are benzimidazopyrimidine benz(cd)indole meroapocyanine cpds. (I) of formula (I) (in which n is 0-3. R1 is H, Cl, Br, alkyl, alkoxy, nitro or arylmercapto. R2 is H or Cl. R3 is H, Cl, Br, alkyl, alkoxy, nitro, acylamino, alkyl- or aryl-sulphonyl(amino), alkyl- or aryl-mercapto, opt. N-substd. sulphonamido, alkanoyl, aroyl, alkoxycarbonyl, opt. substd. carbamoyl or CN. R4 is H, Cl, alkoxy, aryl- or alkyl-mercapto, alkoxycarbonyl, opt. substd. carbamoyl or CN. R3 and R4 together can be thio ortho-phenylene or carbonyl ortho-phenylene. R5 is H, Cl or alkoxy. R6 is opt. 1-4C alkoxy-substd. 1-8C alkyl. R7 is H, Cl, Me or MeO. X is O, NH or 1-4C-acylimino. Y is H or -B(T)2; T is F, Cl, Br or acyloxy). (I) are specified for coloured textiles and plastics (e.g. polyester and natural and synthetic polyamide textiles, polystyrene, polycarbonate, polymethacrylate, polyurethane, polyolefins and other thermoplastics.</p> |
