Claims
- 1. A composition of matter which comprises
- an iridescent pigment of the type comprising an essentially transparent micaceous substrate having thereon at least one overcoating of an essentially transparent material having a refractive index greater than about 2.0,
- and discrete finely divided particles of a diluent which is a water-insoluble, essentially transparent solid having a refractive index less than about 1.8,
- the particles of said diluent comprising up to about 75% of the weight of said composition,
- the diluent particles being admixed among the pigment.
- 2. A composition of matter which comprises a mixture of
- an iridescent pigment of the type comprising an essentially transparent micaceous substrate having thereon at least one overcoating of an essentially transparent material having a refractive index greater than about 2.0, and
- finely divided particles of an oil-soluble dye having an absorption band complementary to the interference reflection color of the iridescent pigment,
- said dye comprising up to about 5% of the weight of said mixture.
- 3. A composition of matter which comprises
- an iridescent pigment of the type comprising an essentially transparent plate-like base substrate having thereon at least one overcoating of an essentially transparent material having a refractive index which is substantially greater than that of said base substrate,
- and discrete, finely divided particles of a diluent which is a water-insoluble, essentially transparent solid having a refractive index less than approximately 1.8,
- the particles of said diluent comprising up to about 75% of the weight of said composition,
- the diluent particles being admixed among the pigment.
- 4. A composition of matter which comprises a mixture of
- an iridescent pigment of the type comprising an essentially transparent plate-like base substrate having thereon at least one overcoating of an essentially transparent material having a refractive index which is substantially greater than that of said base substrate,
- and finely divided particles of an oil-soluble dye which possesses an absorption band complementary to the interference reflection color of said iridescent pigment,
- said dye comprising up to about 5% of the weight of said mixture.
