Abstract: Agent comprises at least a cationic 9-phenyl-4a,9a-dihydro-acridine salt (I). Agent comprises at least a cationic 9-phenyl-4a,9a-dihydro-acridine salt of formula (I). Either R 1>-R 4>H, 1-6C-alkyl, 2-6C-alkenyl, 1-6C-monohydroxyalkyl, 2-6C-polyhydroxyalkyl, halo, carboxyl-, nitrile-, carbamoyl-, sulfonamido-, carboxamido-, alkyloxycarbonyl- or sulfonic acid-group; or R 1>R 2>, R 3>R 4>condensed, carbocyclic or heterocyclic ring optionally containing one or more substituents different from H, which is 1-6C-alkyl, 2-6C-alkenyl, 1-6C-monohydroxyalkyl, 2-6C-polyhydroxyalkyl, carboxyl-, nitrile-, carbamoyl-, sulfonamido-, carboxamido-, alkyloxycarbonyl- or sulfonic acid-group or halo; R 5>1-6C-alkyl, 2-6C-alkenyl, 2-6C-monohydroxyalkyl, 2-6C-polyhydroxyalkyl, 1-6C-alkoxy-1-6C-alkyl, amino-1-6C-alkyl, di-1-6C-alkylamino-2-6C-alkyl or cyano-1-6C-alkyl; either R 6>-R 9>H, 1-6C-alkyl, 2-6C-alkenyl, 1-6C-monohydroxyalkyl, 2-6C-polyhydroxyalkyl, halo, carboxyl-, nitrile-, carbamoyl-, sulfonamido-, carboxamido-, alkyloxycarbonyl-, sulfonic acid-group, 1-6C-alkoxy, hydroxy-2-6C-alkoxy, 1-6C-alkoxy-1-6C-alkoxy, OH, amino or 1-6C-dialkylamino; or R 6>R 7>, R 8>R 9>a 5- or 6-membered, optionally saturated carbocyclic or heterocyclic ring; R 10>H, 1-6C-alkyl, 2-6C-alkenyl, 2-6C-monohydroxyalkyl, 1-6C-alkoxy-2-6C-alkyl, aryl or heteroaryl; and X ->a monovalent anion, preferably halide, hydrogen sulfate, semisulfate, p-benzenesulfonate, p-toluenesulfonate, acetate, tetrafluoroborate, trifluoromethane sulfonate, hexafluorophosphate, methane sulfate or methane sulfonate. Independent claims are included for: (1) coloring and optionally brightening of keratin fibers, preferably human hairs, comprising optionally applying a pretreating agent (M1) on the fibers, applying an agent (M2) on the fibers, where optionally the agent (M2) is added before the use of a further agent (M3), washing the agent (M2) after 5-30 minutes, optionally applying a posttreating agent (M4) on the fiber, after the treatment step, and washing the agent after an impact time of some minutes, where at least one (M1)-(M3) is the agent; and (2) a cationic 9-phenyl-4a,9a-dihydro-acridine compound of formula (Ib). R1a-R4a : H; R5a : 1-6C-alkyl; either R6a-R9a : H, 1-6C-alkyl, 2-6C-alkenyl, 1-6C-monohydroxyalkyl, 2-6C-polyhydroxyalkyl, halo, carboxyl-, nitrile-, carbamoyl-, sulfonamido-, carboxamido-, alkyloxycarbonyl-, sulfonic acid-group, 1-6C-alkoxy, hydroxy-2-6C-alkoxy, 1-6C-alkoxy-1-6C-alkoxy, OH, amino or 1-6C-dialkylamino; or R6aR7a, R8aR9a : a 5- or 6-membered, optionally saturated carbocyclic or heterocyclic ring, provided that at least one of R6a-R9a is H; R10a : H, 1-6C-alkyl, 2-6C-alkenyl, 2-6C-monohydroxyalkyl, 1-6C-alkoxy-2-6C-alkyl, aryl or heteroaryl; and X ->a monovalent anion, preferably halide, hydrogen sulfate, semisulfate, p-benzenesulfonate, p-toluenesulfonate, acetate, tetrafluoroborate, trifluoromethane sulfonate, hexafluorophosphate, methane sulfate or methane sulfonate.
