Embodiment I-1

[0617] (preparation of sample A)

[0618] A phthalocyanine compound (exemplary compound I-101, an oil-soluble dye) (5.3 g) and 7.04 g of dioctyl sodium sulfosuccinate were dissolved in 4.22 g of the following high-boiling organic solvent (s-2) at 70°C , 5.63g of the following high boiling point organic solvent (s-11) and 50mL of ethyl acetate. To this solution was added 500 mL of deionized water while stirring with a magnetic stirrer to prepare an oil-in-water type crude dispersion. Next, the crude dispersion was passed through a microfluidizer (MICROFLUIDEX INC) 5 times under a pressure of 600 bar, thereby forming fine particles. Furthermore, the resulting emulsion was desolventized by a rotary evaporator until the odor of ethyl acetate disappeared. To the thus obtained fine emulsion of the hydrophobic dye, 140 g of diethylene glycol, 50 g of glycerin, 7 g of SURFYNOL 465 (manufactured by Air Products & Chemicals) and 900 mL of deionized water were added to prepare an ink. ...

Embodiment I-2

[0674] Using the same prepared cartridge as in Example I-1, the image was printed on the wax photo paper EX manufactured by Fuji Photo Film by the same equipment as in Example I-1, and then the same as in Example I-1 way of evaluation. Results Similar results to Example I-1 were obtained.

Embodiment I-3

[0676] The same ink prepared in Example I-1 was packaged in a cartridge of an inkjet printer BJ-F850 (manufactured by CANON). Using this cartridge, images were printed onto inkjet paper glossy photo paper GP-301 by the same equipment, and then evaluated in the same manner as in Example I-1. Results Similar results to Example I-1 were obtained.

Abstract

Inks characterized by containing at least one compound selected from among phthalocyanine compounds represented by the general formulae (I), (II), (III) and (IV) have absorption properties with an excellent color reproducibility as a primary color colorant and sufficient fatness against light, heat, moisture and active gases in the surroundings. Thus, these inks can provide colored images and colored materials being excellent in color hue and fastness. They are usable in, for example, printing ink compositions for inkjetting and the like, ink sheets to be used in thermal transfer image-forming materials, electrophotographic toners, various coloring compositions such as coloring compositions for color filters to be used in LCD, PDP and CCD and liquid dyes for various fibers, etc.

Description

technical field [0001] The present invention relates to a novel phthalocyanine compound and a colored imaging composition containing the compound. Specifically, the present invention relates to an oil-soluble ink for cyan inkjet, an inkjet recording method and a method utilizing the inkjet The ink records a method of improving the ozone gas fading resistance (hereinafter sometimes referred to as "ozone gas resistance") of an image recording material. Background technique [0002] In recent years, as colored image forming materials, materials especially for forming color images are mainly popular. Specifically, inkjet mode recording materials, thermal transfer mode recording materials, electrophotographic mode recording materials, transfer mode silver halide photosensitive materials, printing inks, recording pens, and the like are widely utilized. Also, color filters are used for recording and reproducing color images in pixels such as CCDs in photograph...
