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:(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.(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(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.
摘要:
An image-forming method using color ink having a surface tension of 25 to 40 dyne/cm. The color ink is applied to a glossy recording medium having a porous structure including a pigment, a binder and a cationic material.
摘要:
A recording paper comprising pulp fibers and a filler has a surface where pulp fibers bared to the surface and pulp fibers covered with particles are present together in portions. The quantity of ink transfer at a minimum ink-shoot time interval for adjacent dots with different colors as measured by the Bristow's test method is not smaller than a maximum shot-in ink quantity per unit area of recording system used.

摘要:
A cast coated paper for ink jet recording is constituted to include, in lamination: a base paper, an undercoating layer comprising a pigment and an adhesive, and a cast-coating layer comprising a polymer having a glass transition point of at least 40.degree. C. formed by polymerization of an ethylenically unsaturated monomer. The cast coated paper is preferably controlled to have an air permeability of at most 300 sec/100 cc. The undercoating preferably contains a cationic resin, particularly preferably a copolymer of a polyalkylenepolyamine and dicyandiamide. The cast coated paper thus produced with an excellent ink absorptivity suitable for ink jet recording while retaining a high surface gloss.
摘要:
A cast coated paper for ink jet recording is prepared by a process including the steps of: forming on a base paper an undercoating layer containing alumina having a bulk density of at most 0.2 g/cm.sup.3 and an adhesive, applying onto the undercoating layer an overcoating liquid containing a resin to form a wet overcoating layer, and pressing the wet overcoating layer against a heated drum having a mirror-finished surface to dry the overcoating layer, thereby forming a cast-coating layer. The resultant cast coated paper shows not only good gloss and ink jet recording performances (inclusive of ink absorptivity and recorded image density), but also good weather-fastness of recorded images.
