发明名称 Image forming process employing liquid composition and ink in combination
摘要 Provided is a process for the formation of an image employing a liquid composition and a colored ink in combination to form a colored image on a recording medium, comprising using at least a magenta ink as the colored ink, wherein said magenta ink provides an image of magenta color, which satisfies all color senses represented by the following equations:where in the formulae (I), (II), (III) and (IV), L1*, a1*, b1*, a0* and b0* each represent a colorimetric value which is defined in the CIE 1976 (L*a*b*) color space; a1* and b1* each represent a colorimetric value of the image, which is obtained by using a liquid composition and a colored ink on a test paper having a whiteness of from 78 to 84, in accordance with JIS P 8123, measured by a Hunter Whiteness meter, and a chromaticity of 86<=L*<=93, 3<=a*<=10 and -6<=b*<=1, said chromaticity being defined in the CIE 1976 (L*a*b*) color space; and a0* and b0* each represent a colorimetric value of the image, which is obtained by using only a colored ink on said test paper.
