A color shifting multilayer interference film is provided which may be used to produce flakes for use in colorants having color shifting properties. The flakes can be interspersed into liquid media such as paints or inks which can subsequently be applied to objects or papers to achieve color variations upon shifts in angle of incident light or upon shifts in viewing angle. A five layer design of the interference film includes a first absorber layer, a first dielectric layer on the first absorber layer, a reflector layer on the first dielectric layer, a second dielectric layer on the reflector layer, and a second absorber layer on the second dielectric layer. A three layer design of the interference film includes first and second absorber layers with a dielectric layer therebetween. The dielectric layers are formed to have an optical thickness at a design wavelength that provides a color shift as the angle of incident light or viewing changes.

An object of the present invention is to provide a toner which: is excellent in fixing ability such as low-temperature fixability, hot offset property, and separability even in a fixing system excellent in quick start property and energy saving property; has high gloss; and is excellent in development stability and transferability irrespective of environments. The toner of the present invention includes toner particles each containing at least a binder resin and a colorant, in which, in a case where a tetrahydrofuran (THF) insoluble matter of the binder resin in the toner when the toner is subjected to Soxhlet extraction with THF for 2 hours is represented by A (mass %), a THF insoluble matter of the binder resin in the toner when the toner is subjected to Soxhlet extraction with THF for 4 hours is represented by B (mass %), a THF insoluble matter of the binder resin in the toner when the toner is subjected to Soxhlet extraction with THF for 8 hours is represented by C (mass %), and a THF insoluble matter of the binder resin in the toner when the toner is subjected to Soxhlet extraction with THF for 16 hours is represented by D (mass %), A, B, C, and D satisfy the following expression: (A−B) / 2>(B−C) / 4>(C−D) / 8 where 40<A≦75 (mass %) and 1.0<D<40 (mass %).

An ink set providing reduced differential lightfade and graininess. The ink set comprises at least one dark inkjet ink and at least one light inkjet ink. The dark inkjet ink comprises at least one pigment having a high chromaticity and a low lightfastness and the light inkjet ink comprises at least one less chromatic pigment having a high lightfastness. The pigment in the dark inkjet ink is dissimilar from the pigment in the light inkjet ink in at least one of a crystal form, particle size, chromophore, and chemical dispersant. A method of reducing differential lightfade and graininess in a printed image is also disclosed.

Topical compositions comprising at least one matte-finished interference pigment combined with one or more microsphere(s) and elastomer(s) are provided, as well as methods for using such compositions in cosmetics and dermatological products that afford high coverage of flaws or imperfections, while maintaining a natural-looking appearance. These cosmetics and dermatological products can improve the aesthetic appearance of skin, hair, or nails when topically applied thereto.
