摘要： A modified pigment that may include a polymer. The pigment may be directly attached to a nitrogen atom. The nitrogen atom may be attached directly or indirectly to a group that may include -S-Z. S may be a substituted or unsubstituted alkyl group, substituted or unsubstituted aromatic group, or polymer chain having a molecular weight range from about 300 to about 20000. Z may be a hydrogen, carboxyl, sulfonyl, phenolic, phosphoryl, ammonium, trimethylammonium, or tributylammonium group. Also, a modified pigment that may include a polymer. The pigment may be attached to an organic group through a carbon atom that is part of a N-C=N bond. A cosmetic formulation that may include a pigment covalently bonded to an organic group.

摘要： A method of modifying a pigment that includes reacting a reactive compound having an X-[Y]n reactive group with a secondary compound N-S-ZM to form a substituted reactive intermediate [Y]a-X-(N-S-ZM)b. A pigment is reacted with the substituted reactive intermediate [Y]a-X-(N-S-ZM)b to attach the substituted reactive intermediate to the surface of the pigment to form a surface modified pigment. X may be a sulfonyl, phosphoryl, or 1,3,5-triazinyl group, Y may be a halogen leaving group, N may be a basic nucleophilic group, S may be an organic group, and ZM may be an ionizable end group. Also, n is an integer between 1 and 3, b is an integer between 1 and 3, and a=n−b. When n is equal to or greater than b, and if b is 2 or 3, each N-S-ZM can be the same or different.
