<P>PROBLEM TO BE SOLVED: To provide a colored resin emulsion which excels in clarity and color reproducibility, does not generate depolarization, and can obtain a green coating film exhibiting excellent color properties, an inkjet printing ink using the above emulsion, and a color filter using the above ink. <P>SOLUTION: The colored resin emulsion has a coating film which meets all conditions that (1) in the wavelength band of 400-700 nm, the minimum absorption wavelength (λmin) at which the absorbance becomes smallest is present in the wavelength band of 550-570 nm; (2) the transmittance in the wavelength band of 500-570 nm is ≥90% in a coating film having a color density at which the transmittance in the above λmin comes to 95%; (3) the transmittance in the wavelength band of 630-700 nm is ≤50% in the above coating film; and (4) the transmittance in the wavelength band of 400-470 nm is ≤50% in the above coating film. The inkjet printing ink is obtained by adding a humectant to the above emulsion, and the color filter is produced by using the inkjet printing ink. <P>COPYRIGHT: (C)2003,JPO |
