摘要： A pigmented ink composition comprising a pigment, a resin having an acidic group and an organic solvent having a boiling point of at least 150°C which is present in an amount of from 50 to 90% by weight based on the whole weight of the ink composition. When this ink composition is subjected to an printed layer-sliding test in which the ink composition is applied on a cationically treated printing medium with a #4 bar coater (available from TOYO SEIKI KOGYO CO., LTD.)and dried and then the printed surface is slid with a cloth on which a weight of 50 g is placed, the printed record is not grazed. This ink composition contains the pigment with a small dispersion particle size and has good water resistance, can be printed on a plain paper sheet without cockling, and suffers from no grazing of printed records when the ink composition is printed on a cationically treated paper sheet.

摘要： A pigment ink composition comprising a pigment, a resin having an acid group and an organic solvent of 150ºC or higher boiling solvent, wherein the organic solvent occupies 50 to 95 wt.% of the whole ink composition. This pigment ink composition is free from friction marks on coating film in a coating film sliding test in which a cation-treated recording medium is coated by means of bar coater #04 (manufactured by Toyo Seiki Seisaku-sho, Ltd.) and dried and the resultant coating film is subjected to sliding with a cloth having a weight of 50 g placed thereon. In this pigment ink composition, the diameter of dispersed pigment particles is small. The pigment ink composition realizes excellent water resistance, enables printing on plain paper without cockling and exhibits such a high anti-friction performance that problems of friction marks on prints would not occur in the printing of cation-treated recording medium.
