PROBLEM TO BE SOLVED: To provide a coating composition capable of evenly forming a metallic coating film with high luminance, even when coating using a brush or roller.SOLUTION: A coating composition includes a flaky metal pigment and a coloring pigment. A content of a non-volatile component in the coating composition is 35-60 mass%. A pigment volume concentration in the non-volatile component is 10-25 vol.%. A contrast ratio is 0.1-50% when the flaky metal pigment is removed from the non-volatile component in the coating composition. Here, the contrast ratio is measured in compliance with JIS K-5600-4-1 method B.SELECTED DRAWING: None 【課題】刷毛やローラーを用いて塗装を行う際にもムラなく高輝度な金属調塗膜を形成することが可能な塗料組成物を提供する。【解決手段】鱗片状金属顔料及び着色顔料を含む塗料組成物であって、該塗料組成物中における不揮発分の含有量が３５〜６０質量％であり且つ該不揮発分中における顔料体積濃度が１０〜２５体積％である塗料組成物であり、前記塗料組成物の不揮発分から鱗片状金属顔料を除いた場合の隠蔽率が０．１〜５０％であり、ここで、隠蔽率はＪＩＳ Ｋ−５６００−４−１方法Ｂに従って測定されることを特徴とする塗料組成物である。【選択図】なし
