Use of unsaturated aldehydes in dying fibers containing keratin

The invention relates to the use of unsaturated aldehydes of formulae (Ia) or (Ib), wherein R , R , R and R 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 and R , R and R , R and R and R and R ca...

Zusammenfassung:	The invention relates to the use of unsaturated aldehydes of formulae (Ia) or (Ib), wherein R , R , R and R 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 and R , R and R , R and R and R and R 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.
