Abstract
Disclosed is an ink jet recording method which can efficiently realize good images, particularly an ink jet recording method which can realize, on plain papers, high-quality prints free from feathering or color-to-color mixing at a relatively low heating temperature, and an ink composition for use in this method.An ink composition comprising at least a colorant, a water-soluble organic solvent, water, and at least one compound represented by formula (I) is printed on a recording medium heated at a temperature of or above the cloud point of the compound represented by formula (I):R—[O—(EO)m—(PO)n]—Hwherein EO represents an ethyleneoxy group; PO represents a propyleneoxy group; m and n are each an integer; k is a natural number of 1 or more; and R represents CkH2k−1 wherein k is a natural number of 4 to 18, EO and PO being arranged, regardless of order in the parentheses, randomly or as blocks joined together.
