The multicomponent packaging unit according to claim 1, wherein
the first preparation (A) contains, based on the total weight of preparation (A),
(A1) one or more resorcinol derivatives from the group comprising resorcinol, 2-methylresorcinol, and 4-chlororesorcinol in a total amount of from about 1.0 to about 15.0% by weight.

### Claim 3 (depends on 1)

The multicomponent packaging unit according to claim 1, wherein
the first preparation (A) contains
(A2) one or more developer-type oxidation dye precursors, which are selected from the group comprising p-phenylenediamine, p-toluylenediamine, 2-(2-hydroxyethyl)-p-phenylenediamine, N,N-bis(2-hydroxyethyl)-p-phenylenediamine, 2-methoxymethyl-p-phenylenediamine, N-(4-amino-3-methylphenyl)-N-[3-(1H-imidazol-1-yl)propyl]amine, bis(2-hydroxy-5-aminophenyl)methane, p-aminophenol, 4-amino-3-methylphenol, 4,5-diamino-1-(2-hydroxyethyl)pyrazole, 2,4,5,6-tetraaminopyrimidine, and/or the physiologically acceptable salts thereof.

### Claim 4 (depends on 1)
