PURPOSE: To easily and efficiently produce an iridescent luster pigment exhibiting bright reflective interference color. ;CONSTITUTION: An iridescent luster pigment is produced by coating a transparent flaky substrate with titania, zirconia or their mixture and heat-treating the coated product. In the above process, the transparent flaky substrate has a light transmittance of ≤50% for at least a part of light of a wavelength range of 400-800nm and is produced from a solution containing a hydrolyzable and polycondensable organometallic compound and a substance causing the light absorption.;COPYRIGHT: (C)1994,JPO&Japio
