摘要:
An ink-jet recording apparatus includes an ink-jet recording head having a nozzle from which ink is ejected on the basis of print data, an ink-receiving unit that receives the ink ejected from the nozzle, and a surface-tension-depressant-solution supplying unit that supplies a liquid composition containing a surface tension depressant to the ink-receiving unit when the ink is ejected from the nozzle into the ink-receiving unit.
摘要:
A method for obtaining and evaluating a white color shielding degree of a white color printed material includes the steps of: measuring an L* value of the white color printed material; obtaining an integrated value of transmittance of the white color printed material in a visible light region; and obtaining the white color shielding degree from the L* value and the integrated value.
摘要:
An image-forming method includes a first image-forming step of forming an image on a fabric with a first ink composition and a second image-forming step of forming an image on the fabric with a second ink composition subsequently to the first image-forming step. The first ink composition contains a first colorant. The second ink composition contains a second colorant. The first colorant has an average particle size less than that of the second colorant.
摘要:
A white ink composition contains a white coloring material and a fixing resin component. The fixing resin component includes a styrene acrylic resin and a urethane resin at a mass ratio of the styrene acrylic resin to the urethane resin (styrene acrylic resin/urethane resin) of at least 1/10.
摘要:
A recording device forming a printed image by discharging droplets of an image forming solution from a nozzle and attaching the droplets on recording media, which includes a recording head provided with a specific nozzle which is selectively filled with the image forming solution and a solution preventing the nozzle from being clogged, and a controller that controls the performance of switching from a first filled state in which the specific nozzle is filled with the image forming solution to a second filled state in which the specific nozzle is filled with the solution preventing the nozzle from clogging in accordance with a predetermined condition.

摘要:
A water resistant aluminum pigment dispersion includes an aluminum pigment covered with a silica film, which is dispersed in an aqueous solution containing at least one selected from the group consisting of a copolymer A including a structural unit represented by the following general formula (1) or the following formula (2) and a structural unit represented by the following general formula (3), a copolymer B including a structural unit represented by the following general formula (1) or the following formula (2) and a structural unit represented by the following general formula (4), and a copolymer C including a structural unit represented by the following general formula (1) or the following formula (2) and a structural unit represented by the general formula (5)
摘要:
A method for producing water-repellent treated aluminum pigment dispersion includes (a) adding a polysilazane solution in which a polysilazane is dissolved in a second organic solvent to an aluminum pigment dispersion in which an aluminum pigment is dispersed in a first organic solvent for reacting a hydroxyl group present on the surface of the aluminum pigment with the polysilazane to form a covering film on the surface of the aluminum pigment. The amount of the polysilazane in the reaction system for forming the covering film is 0.4 parts by mass or less based on 1 part by mass of the aluminum pigment, and the total addition amount of the polysilazane is from 0.2 to 0.6 parts by mass based on 1 part by mass of the aluminum pigment.
