Multicomponent composition (Michael addition)
The instant disclosure generally relates to a multicomponent composition for coating mammalian or synthetic keratin material and textiles, the composition comprising a first and second components and a third component. The first and second components comprise first and second compounds respectively. Any one or more of the first, second and third components may also comprise pigment microparticles. The first, second and third compounds meld together on keratin material and textiles and especially on hair to form a coating that can be formulated to provide temporary coverage or provide permanent coverage. The multicomponent composition formed and set in situ as a solid linked coating ranges from ready removability to substantially permanent lastingness.
