Claim:
A dye of the formula (I) where D is the radical of a diazo component; R 1 is hydrogen, (C 1 -C 6 )-alkyl, (C 1 -C 4 )-alkoxy, hydroxyl, halogen, —NHCHO, —NHCO(C 1 -C 6 )-alkyl, —NHCOaryl, —NHSO 2 (C 1 -C 6 )-alkyl or —NHSO 2 aryl; R 2 is hydrogen, (C 1 -C 6 )-alkyl, (C 1 -C 4 )-alkoxy, phenoxy or halogen; R 3 is hydrogen, (C 1 -C 6 )-alkyl, substituted (C 1 -C 6 )-alkyl, (C 3 -C 4 )-alkenyl or substituted (C 3 -C 4 )-alkenyl; or R 2 and R 3 combine to form the radical —C*H(CH 3 )CH 2 C(CH 3 ) 2 —, where the carbon atom marked by * is attached to the phenyl nucleus; R 4 is hydrogen, (C 1 -C 6 )-alkyl or phenyl; R 5 is (C 1 -C 6 )-alkyl or substituted (C 1 -C 6 )-alkyl; R 6 is hydrogen or (C 1 -C 6 )-alkyl; R 7 is hydrogen, (C 1 -C 6 )-alkyl or phenyl; and n 0, 1, 2 or 3; although the compounds of the formulae shall be excluded.
