<P>PROBLEM TO BE SOLVED: To provide an ink for inkjet recording, providing a monotone deep and light image hardly being wholly yellowish, and having smooth tone between an ink-imparted part and an ink-unimparted part achieved in a light-transmitting medium, and effective for prevention of a false outline of the image. <P>SOLUTION: The ink for the inkjet recording includes a dye usable for recording multitone image on the light-transmitting medium in combination with an ink group consisting of three kinds of ink having the same hue and concentrations of a coloring material different from each other. The ink has a hue different from the hue of each ink constituting the ink group, and the difference (ΔC<SP>*</SP>) represented by CIELAB color space between an ink-imparted part and an unimparted part on the light-transmitting medium satisfies the formula (I): ΔC<SP>*</SP>=(Δa<SP>*2</SP>+Δb<SP>*2</SP>)<SP>1/2</SP>≤5 (I); when the ink is imparted to the light-transmitting medium by an inkjet method by 100% duty. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
