Pigment comprising particles each containing calcium-titanium composite oxide as main component, method for producing same, and use of same

A pigment comprising particles containing a calcium-titanium composite oxide as a main component, wherein

• when the particles of the calcium-titanium composite oxide in the pigment are observed in a transmission electron microscopic image at a magnification of 100,000×, at least one area of the image is lighter in color than its surroundings, and
• the pigment has a true density of 3500 kg/m3 or more and 3790 kg/m3 or less;
• wherein the pigment is produced by:
• mixing an acid deflocculant of a hydrolyzate of a titanium compound, an alkali, and a water-soluble compound containing calcium to obtain a mixture, and heating the mixture to 70° C. or higher and 100° C. or lower under atmospheric pressure to produce a reaction product;
• cooling the obtained reaction product, followed by allowing to stand at pH 7.0 or less for 1 hour or more;
• subjecting the reaction product after allowed to stand to solid-liquid separation to collect a solid;
• and
• firing the solid at 500° C. or higher.
