摘要: Abstract Condensation of 4-halogeno-1,8-naphthalic anhydride with the appropriate cyclic secondary amines gives 4-morpholino-, 4-piperidino-, 4-pyrrolidino- and 4-piperazino- derivatives. These intermediates afford yellow to orange dyes for synthetic-polymer fibres when condensed alkylamines, arylamines o-phenylenediamines. Also described are 4-imidazolo- pyrido [5,6-c]-1,8-naphthalic anhydrides; imides these colourless, but derived 7H-benzimidazo[2,1-a]benz[d,e]isoquinolin7-ones dyes. Coloration fastness properties many derivatives on polyester good. The effect an additional nitro group ortho amino substituents is also investigated.
