Abstract
An ink-jet recording method for forming an image on a recording medium by ejecting ink droplets through an orifice of a recording head in response to a recording signals comprises ejecting an ink having a surface tension ranging from 25 to 35 dyn/cm onto a recording medium constituted of a base sheet and a coating layer formed on the base sheet to form an image, the coating layer being selected from (a), (b), and (c) below: PA0 (a) a coating layer mainly composed of polyvinyl alcohol of a saponification degree of from 75 to 98 mol % and a polymerization degree of from 100 to 500, or a derivative thereof. PA0 (b) a coating layer mainly composed of a copolymer of vinylpyrrolidone with a vinyl monomer having a hydrophobic group, and a polyalkylene oxide or a derivative thereof, and PA0 (c) a coating layer mainly composed of an aromatic polyvinylacetal resin, and a polyalkylene oxide or a derivative thereof. A color image forming method forming a color image on a recording medium employing four color-inks of yellow, cyan, magenta, and black comprises ejecting inks having the surface tension onto the recording medium.
