Abstract
The pigment is composed of particles having a lattice constant a of 5.4700-5.5100 Å and containing a calcium-titanium composite oxide as a main component. The pigment selectively transmit light in a warm-color range, and can be used as an alternative material for titanium oxide. This pigment can be used for a cosmetic, for example.
Claims13
A pigment composed of particles comprising a calcium-titanium composite oxide as a main component, wherein a lattice constant a of the pigment is in a range of 5.4700 Å or more and 5.5100 Å or less,
- wherein, when the pigment is measured in X-ray diffractometry, and when a height of a diffraction line of a (1 2 1) plane appearing in a range of a diffraction angle of 32.50° or more and 33.50° or less is defined as 100.0, a height of a diffraction line of a (2 0 2) plane appearing in a range of a diffraction angle of 46.75° or more and 47.75° or less is 50.0 or less.
