  • Pigment and process for producing the same, water base ink and process for producing the same
    Patent number: 6287374
    Abstract: In the present invention, a pigment is irradiated with a microwave so as to improve a surface thereof. Further, letting A be an area of a portion having hydrophilic groups on a surface of the pigment and B be an area of the other portion thereon, which are respectively found by measuring infrared spectrometers of the pigment, a ratio (A/B) is not less than 4. Water base ink according to the present invention is obtained by dispersing such a pigment in an aqueous medium.
