    摘要： An aqueous pigment dispersion comprising:

    (a) 100 parts by weight of a pigment;
    (b) 3 to 30 parts by weight of at least one sulfonic acid group-containing derivative of a pigment of the same pigment type as (a); and
    (c) water,
       wherein (i) component (b) comprises a pigment derivative which has only one sulfonic acid group in each molecule, (ii) at least part of the pigment derivative (b) is present, in the dispersion, in the form of a sulfonic acid salt selected from an ammonium salt, an organic amine salt and a salt with a monovalent metal, provided that at least 15% of the sulphonic acid groups do not form a salt with the monovalent metal, and (iii) the dispersion contains 500 ppm or less of solid metal ions having a valence of at least 2.

    摘要： The present invention relates to an ink jet recording liquid obtained by dispersing a pigment in an aqueous medium, said aqueous medium comprising glycerol and 1,3-propanediol. The ink jet recording liquid of the present invention is capable of sustaining prolonged stable discharge onto the recording surface without clogging the nozzle of an ink jet printer and exhibits excellent storage stability.
