Patent number: 6036767Abstract: The present invention provides an aqueous pigment dispersion composition for electro-deposition color coating of an aluminum or aluminum alloy oxide film, the composition comprising an organic white pigment as an essential component thereof. The organic white pigment comprises large-diameter particles which are insoluble in a water-soluble organic liquid and/or water and exhibit a non-skinning property and a sufficient concealing power on an aluminum or aluminum alloy oxide film. More specifically, the organic white pigment particles preferably have an average particle diameters of at least 0.3 .mu.m and a reflective index of at least 1.4. The use of the aqueous pigment dispersion composition for electro-deposition coating ensures formation of a less lustrous, less transparent and highly weather-resistant coating film for coloration of an aluminum or aluminum alloy oxide film.Type: GrantFiled: May 30, 1997Date of Patent: March 14, 2000Assignee: Sakura Color Products CorporationInventors: Shigeyasu Inoue, Tadaaki Ito
