Multicomponent composition

A multicomponent in situ linkable composition for coloring keratin material, comprising:

• a first component comprising a linear or branched organic polymer comprising a polyolefin, a polyvinyl, a polyester, a polyether, a polyamide, a polyurethane or any combination thereof to which is covalently linked pendant and/or terminal first functional groups;
• a second component comprising an in situ linking material;
• comprising a linear and/or branched organic or silicone core to which is bonded second functional groups;
• a third component comprising a base compound having third functional groups comprising amine groups;
• pigment microparticles in one or more of the first, second and third components, wherein
• the first and second functional groups are complementary reactive pairs, which comprise a) Si—OH/SiOR and Si—OR/Si—OH;
• b) epoxy and hydroxy, amine or mercapto or any combination of hydroxy, amine and mercapto;
• c) carboxyl and hydroxyl or amine or a combination of hydroxyl and amine;
• and d) (meth)acryloxy or crotonyloxy and hydroxy, amine or mercapto or any combination of hydroxy, amine and mercapto;
• and,
• the first, second components are separate or together.
