1. A multicomponent in situ linkable composition for coloring keratin material, comprising:
a first component comprising a CDI link compound having at least two groups capable of covalent in situ linkage with a carbodiimide group, the groups being carboxylic acid groups, sulfonic acid groups, phosphoric acid groups or any combination thereof and the CDI link compound having inert or first reactive termini, the first reactive termini being self-reactive alkoxysilyl groups or hydroxysilyl groups or a combination thereof;
a second component comprising an in situ linking material having at least two carbodiimide groups and having second reactive termini, the second reactive termini being self-reactive alkoxysilyl groups or hydroxysilyl groups or a combination thereof;
the second reactive termini of the in situ linking material and the first reactive termini CDI link compound being independently selected; and,
pigment microparticles in one or both of the first and second components; or as a separate component; and,
wherein the first and second components are present in separate container units; and
wherein the first and second components are combinable to form a mixture of first and second components for coloring keratin material.
