Abstract:
Carbon black-containing composite particles of the present invention each include a silicon oxide and carbon black particles dispersed inside the silicon oxide. When a coating film containing the carbon black-containing composite particles dispersed in a transparent matrix, having a concentration of the carbon black particles of 1 mass %, and having a thickness of 25 μm to 40 μm is formed on a hiding-chart specified in JIS (Japanese Industrial Standards) K 5600-4-1: 1999, a difference L W *−L B * obtained by subtracting lightness L B * of the coating film formed on a black part of the hiding-chart from lightness L W * of the coating film formed on a white part of the hiding-chart is 30 or less. Thus carbon black-containing composite particles advantageous in exhibiting a good hiding property and reducing an undertone can be provided.

Claim (Index 1):
