Abstract
Provided is a flaky titanate that exhibits a high weathering resistance while at the same time having the ability to endow a coating film with a silky feeling having a shading feeling and a strong luster feeling, and a method for the production thereof suitable at least for inexpensive industrial production. The flaky titanate contains a basic organic compound wherein the content of basic functional groups thereof is not more than 2.4%, and provides a coating film having a goniospectrophotometric color measured value ΔL* of at least 150. The method for producing a flaky titanate contains a step of classifying a flaking titanate having a basic organic compound at the surface and/or in interlayer position, to bring (D90−D10)/D50 in the volume particle size distribution to 1.5 or less.
Claims16
A flaky titanate having (D90−D10)/D50 of 1.5 or less in a volume particle size distribution measured by a laser diffraction/scattering method,
- wherein the D10, D50, and D90 express a cumulative 10% particle size, a median size, and a cumulative 90% particle size, respectively, and the D10 is 9 μm or more and
- wherein the flaky titanate comprises a basic organic compound and having a basic functional group content of 2.4% or less.
