Abstract: The present invention provides a multilayer coating film-forming method that is capable of forming a multilayer coating film with excellent finished appearance and excellent luster. The aqueous base paint (X) is applied by using a rotary-atomization bell-shaped coater under coating conditions of a shaping air pressure of 0.15 to 0.25 MPa and a paint discharge amount of 100 to 300 cm3/min. The viscosity 60 seconds after the application of the aqueous base paint (X), measured at a temperature of 23° C. and a shear rate of 0.1 sec-1, is 90 to 160 Pa·s, the solids content 60 seconds after the application is 20 to 40 mass %, and the film thickness 60 seconds after the application is 17 to 35 ?m.

Abstract: A method for producing a luster pigment containing a plurality of scaly pigment particles that is capable of suppressing reactions between an aluminum layer as a core layer of each pigment particle and water, even when the luster pigment is exposed to atmosphere containing oxygen or water. The method includes forming a first layer on a surface of a film substrate through deposition of titanium as material, forming a second layer on a surface of the first layer through deposition of aluminum as material, and forming a third layer on a surface of the second layer through deposition of titanium as material, so as to form a stack including the first layer, second layer, and third layer stacked in sequence on the surface of the film substrate, and removing the stack from the film substrate and crushing the removed stack, so as to produce the plurality of scaly pigment particles.
