Abstract (en)
[origin: WO03024917A1] The present invention relates to novel bridged p-phenylenediamines, the use thereof as developer components in oxidation dyes as well as novel oxidation dyes, which contain the aforementioned bridged p-phenylenediamines. Said invention also relates to a method for producing said bridged p-phenylenediamines. Within the frame of said invention, it was discovered that polyoxyalkyl-bridged p-phenylenediamines of formula (I) are extremely well-suited for use as developer components in oxidation dyes.
