Abstract (en)

[origin: DE19717224A1] The invention relates to the use of unsaturated aldehydes of formulae (Ia) or (Ib), wherein R<1>, R<2>, R<3> and R<4> independently mean hydrogen, halogen, a C1-C4-alkoxy, C1-C4-alkyl, aryl radical or a C1-C4-alkoxy-C1-C4-aryl radical and n stands for 1 or 2, wherein R<1> and R<2>, R<1> and R<3>, R<2> and R<3> and R<2> and R<4> can form together with a residual molecule a ring with 5 to 7 units when n equals 1, in addition to the corresponding mono, bis or omega -alkoxy acetals, for the dying of fibers containing keratin, specially human hair.
