Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 本発明の目的は、印字部と非印字部との光沢 差による違和感を改良し、かつ印字部でのぎらつき感の 低減及び高い印字濃度を得ることができるインクジェッ ト記録方法を提供することにある。 【解決手段】 支持体上にインク吸収層を有する記録媒 体上に、イエロー、マゼンタ及びシアン顔料インクを用 いたインクジェット記録方法において、該記録媒体が、 インク吸収層面側表面のJIS−Z−8741に規定さ れる60度鏡面光沢が10〜30%、JISB−060 1に規定される中心線平均表面粗さRaが0.6〜4. 0μmで、かつブリストー浸透速度が20〜100ml /m 2 ・sec 1/2 であり、該顔料インクの少なくとも一 つが、ゼータ電位の絶対値が30〜100mVの顔料粒 子を含有することを特徴とするインクジェット記録方 法。 (57) Abstract: An object of the present invention is to improve discomfort due to a difference in gloss between a printed portion and a non-printed portion, reduce glare in a printed portion, and obtain a high print density. An object of the present invention is to provide an ink jet recording method. SOLUTION: In an ink jet recording method using a yellow, magenta and cyan pigment ink on a recording medium having an ink absorbing layer on a support, the recording medium comprises: A 60-degree specular gloss defined by JIS-Z-8741 on the ink absorbing layer surface side surface is 10 to 30%, and JIS B-060. The center line average surface roughness Ra defined in 1 is 0.6 to 4.0. 0 μm and Bristow penetration rate of 20-100 ml / M 2 · sec 1/2 , and at least one of the pigment inks contains pigment particles having an absolute value of zeta potential of 30 to 100 mV.
