Multicomponent pur composition
The instant disclosure generally relates to a multicomponent composition for coloring mammalian or synthetic keratin fibers, the multicomponent composition comprising first, second, third and fourth components. The first component includes an organic polymer, the second component includes an in situ linking material, the third component includes a base compound and the fourth component includes a catalyst or other substance. One or more of the components includes pigment microparticles. The multicomponent composition in situ links upon application, forms a solid coating on treated material such as hair and has a substantially long color remanence following development. Methods of using such compositions are also described herein.
