PHOTOLUMINESCENT PIGMENT AQUEOUS-MEDIUM DISPERSION AND PHOTOLUMINESCENT COATING MATERIAL

摘要

To obtain a photoluminescent pigment and a photoluminescent coating material which have no particle feeling and exhibit a highly excellent silky feeling. A dispersion liquid of a photoluminescent pigment in an aqueous medium, characterized in that the photoluminescent pigment is flaky titanic acid obtained by treating layered titanate with acid and then reacting an organic basic compound with the treated layered titanate to delaminate, and the flaky titanic acid has an average longer diameter of 5 to 30 µm and an average thickness of 0.5 to 300 nm.
