Abstract:
An organic-inorganic hybrid pigment composition is provided comprising an organic pigment, an inorganic pigment, and a fibrous clay. The fibrous clay can be selected from palygorskite, sepiolite, or a combination thereof. The inorganic pigment is selected from rutile pigments, spinel pigments, bismuth vanadate pigments, cerium sulfide pigments, and combinations thereof. The organic pigment is selected from anthraquinone pigments, anthrathrone pigments, anthrapyrimidine pigments, azo pigments, azomethine pigments, quinacridone pigments, quinophthalone pigments, diketopyrrolopyrrol pigments, inanthrone pigments, isoindoline pigments, metal complex pigments, perinone pigments, perylene pigments, phthalocyanine pigments, pyranthrone pigments, pyrazolo-quinazolone pigments, thioindigo pigments, and combinations thereof.
