13 Claims

1. A process for dyeing keratinous material comprising:

applying an agent (a) to the keratinous material, the agent (a) comprising at least one organic silicon compound of the formula (I) and at least one organic silicon compound of the formula (IV),

wherein in the organic silicon compound of formula (I)

R1R2N-L-Si(OR3)a(R4)b (I),

R1, R2 independently represent a hydrogen atom or a C1-C8 alkyl group;

L represents a linear or branched, branched C1-C20 alkyl group;

R3 represents a hydrogen atom or a C1-C8 alkyl group;

R4 represents a C1-C8 alkyl group;

a is an integer from 1 to 3; and

b is the integer (3−a); and

wherein in the organic silicon compound of formula (IV),

R9Si(OR10)k(R11)m (IV),

R9 represents a C1-C18 alkyl group;

R10 represents a hydrogen atom or for a C1-C8 alkyl group;

R11 represents a C1-C6 alkyl group;

k is an integer from 1 to 3; and

m is the integer 3−k, and

applying an agent (b) to the keratinous material, wherein the agent (b) comprises:

(b1) at least one colorant compound comprising at least one pigment based on a lamellar substrate platelet, and

(b2) at least one film-forming polymer.
