    Abstract: New 7-amino-quinoline cpds. (I) have the formula: (in which R1 and R2 are H, opt. Cl-, Br-, CN-, OH-, 1-4C alkoxy- or 1-4C carboxylic ester-substd. 1-6C alkyl or benzyl or R1 can be joined with R2 or with the 6-position of aromatic ring A to a 5- or 6-membered ring, opt. including a heteroatom; R3 is a CN, carboxylic ester or carbamide gp. or a N-heterocyclic gp. opt. quaternised at the N; R4 is OH or amino; the aromatic ring A and the heterocyclic gp. possible for R3 can be substd. by Cl, Br, OH, CN, Alkyl, aryl, aralkyl, alkoxy, alkylthio, aryloxy or arylthio gps. with 1-8C, carboxyl, sulphonic ester or sulphonamide gps.). Cpds. (I) are useful as dyes, optical brighteners, colour formers for copying processes and for the prodn. of printing pastes.
