Patent number: 7553365Abstract: An aqueous pigment dispersion is produced by ultrafinely dispersing a pigment dispersion mixture, which has been obtained by mixing at least a pigment and a dispersant in an aqueous medium, with microbeads having diameters of not smaller than 0.02 mm but smaller than 0.2 mm. A color composition for a color filter is produced by dispersing a mixture of a pigment, a dispersant, a resin varnish and a solvent with the microbeads in a mill.Type: GrantFiled: January 25, 2005Date of Patent: June 30, 2009Assignee: Dainichiseika Color & Chemicals Mfg. Co., Ltd.Inventors: Shigeru Sakamoto, Yoshimasa Tsuchiya, Masanori Takakamo, Tohru Hosoda, Akio Yoshida, Michiei Nakamura, Naoyuki Sakai, Dai Watanabe, Hideyuki Koiso, Kenji Ogawa
