Abstract
Abstract Translated from Japanese (57)【要約】 【課題】 不規則なにじみが少なく、印字後素早く乾燥 し、印字濃度が高い印字画像を実現できるインク記録方 法の提供。 【解決手段】 インク組成物の液滴を吐出し記録媒体に 付着させて印字を行うインクジェット記録方法であっ て、前記インク組成物が、顔料、浸透剤、および水を少 なくとも含んでなるものであって、前記顔料が、分散基 をその表面に有する、単独で水性溶媒に分散可能な表面 処理顔料であり、かつ記録媒体へのインク組成物吐出量 が記録媒体5×10 −3 mm 2 あたり160ng以下で ある、インクジェット記録方法。 PROBLEM TO BE SOLVED: To provide an ink recording method capable of realizing a printed image which has less irregular bleeding, dries quickly after printing, and has high printing density. An ink jet recording method for performing printing by discharging droplets of an ink composition and attaching the droplet to a recording medium, wherein the ink composition comprises at least a pigment, a penetrant, and water. The pigment is a surface-treated pigment that has a dispersing group on its surface and can be dispersed alone in an aqueous solvent, and the amount of ink composition discharged onto a recording medium is 160 ng per 5 × 10 −3 mm 2 of the recording medium. The following is an inkjet recording method.
