The invention relates to agents for oxidatively changing the color of keratin fibers, in particular human hair, containing, in a cosmetic carrier (A), at least one oxidation dye intermediate of formula (I) and/or a physiologically acceptable salt thereof, wherein Y1, Y2, and Y4 stand, independently of each other, for a group R5R6N– or for a hydroxy group, Y3 stands for a halogen atom (fluorine, chlorine, bromine, or iodine), for a cyano group, for a group R5R6N–, or for a hydroxy group, X stands for an oxygen atom (–O–), for a sulfur atom (–S–), or for a group –NR7–, R1, R2, R3, and R4 stand, independently of each other, for a hydrogen atom, a C1-C6 alkyl group, a C2-C6 alkenyl group, a hydroxy C2-C6 alkyl group, a polyhydroxy C2-C6 alkyl group, a hydroxy group, a C1-C6 alkoxy group, an amino group, a group R8R9N–, a cyano group, a C1-C6 alkoxy carbonyl group, an aryl group, or a halogen atom (fluorine, chlorine, bromine, or iodine), R5, R6, R7, R8, and R9 stand, independently of each other, for a hydrogen atom, a C1-C6 alkyl group, a C2-C6 alkenyl group, a hydroxy C2-C6 alkyl group, a polyhydroxy C2-C6 alkyl group, or an aryl group, with the stipulation that, if X stands for an oxygen atom (–O–) and Y1, Y2, Y3, and Y4 all stand for a group R5R6N–, at least one of the residues from the group R1, R2, R3, and R4 is different from hydrogen. |
