Zusammenfassung:PROBLEM TO BE SOLVED: To obtain the subject new pigment remarkably improved in light gloss and color brilliance, not expressing a yellow color at a masstone angle part, etc., and not blurring interference colors by coating synthetic mica expressed by a specific shape and a specific index with a metal oxide. SOLUTION: This new pearl gloss pigment is obtained by coating (A) synthetic mica with (B) a metal oxide. Therein, the component A has a thin flaky shape having smooth surfaces and a pearl index expressed by an inequality: (specific volume)×(powder gloss value) >=10, preferably 30>=(pearl index)>=10. The component A has an average refractive index of 1.58, an average aspect ratio of >=60, an ion content of
