Embodiment 1

[0138] The ink composition of embodiment 1:

[0139] Cabojet300 (water-dispersed colorant, water-soluble group: carboxyl group) 2%

[0140] Glycerin 10%

[0141] Ethylene Glycol 5%

[0142] Surfactant of general formula (VIII) (ethylene oxide 10 mole adduct) 2%

[0143] pure water the rest

[0144] The usage-amount of the said ethylene urea is more than a saturation concentration with respect to the usage-amount of glycerin.

Embodiment 2

[0145] The ink composition of embodiment 2:

[0146] Cabojet300 (water-dispersed colorant, water-soluble group: carboxyl group) 2%

[0147] Glycerin 7%

[0148] Ethylene urea 10%

[0149] Surfactant of general formula (VIII) (ethylene oxide 10 mole adduct) 1%

[0150] pure water the rest

Embodiment 3

[0151] The ink composition of embodiment 3:

[0152] Cabojet200 (water-dispersed colorant, water-soluble group: carboxyl group) 2%

[0153] Glycerin 10%

[0154] Ethylene Glycol 5%

[0155] Surfactant of general formula (VIII) (ethylene oxide 10 mole adduct) 2%

[0156] pure water the rest

Abstract

The present invention relates to an ink and a recording method using the ink. The ink of the present invention is characterized in that it is a water-based ink containing water, a water-dispersed colorant, and a liquid medium containing a surfactant. , the above-mentioned water-dispersed coloring material forms a plurality of microagglomerates existing in dots, and is fixed on the recording material.

Description

technical field [0001] The present invention provides a water-based ink, more specifically, provides a water-based ink that can provide a high-grade recorded image, good scratch resistance, fastness, especially water-resistant images, and high reliability, and uses the water-based ink Ink recording image forming method and recording image. As a preferable application, it also relates to a water-based ink having good fluorescence luminescence, a recorded image forming method and a recorded image using the ink. Background technique [0002] Conventionally, among many water-based inks including inks for writing instruments and inks for inkjet recording, various inks have been proposed, studied, and reported for the purpose of improving the fastness of recorded images and recording images well. [0003] Conventionally, water-soluble colorants have been used as colorants for water-based inks, and therefore have good reliability such as resistance to fixation and stability over t...
