A method for producing a water-resistant aluminum pigment dispersion includes (a) adding a treatment agent containing a compound of general formula (1) described below to an aluminum pigment dispersion containing aluminum pigment particles dispersed in an organic solvent and reacting a hydroxy group present on a surface of each of the aluminum pigment particles with the compound of general formula (1) described below to form a film on the surface of each aluminum pigment particle, (b) removing at least a portion of the organic solvent, and (c) adding an aqueous solution containing at least one selected from polyoxyethylene alkyl ether phosphate and salts thereof, (wherein p represents an integer of 1 to 3, q represents an integer that satisfies the equation p+q=3, r represents an integer of 2 to 10, R1 and R2 each independently represent an alkyl group having 1 to 4 carbon atoms, and R3 represents an acrylic group, an acryloyl group, or a methacryloyl group).
摘要:
A method for producing water-repellent treated aluminum pigment dispersion includes (a) adding a glycidyl group-containing compound represented by the following formula (1) to an aluminum pigment dispersion in which an aluminum pigment is dispersed in an organic solvent for reacting a hydroxyl group present on the surface of the aluminum pigment with the glycidyl group-containing compound represented by the formula (1) to form a covering layer on the surface of the aluminum pigment: (in the formula, p represents an integer of 1 to 3, q represents an integer that satisfies a relation of p+q=3, r is an integer of 2 to 10, and R1 and R2 independently represent an alkyl group having 1 to 4 carbon atoms).
摘要:
A water resistant aluminum pigment dispersion includes a water resistant aluminum pigment which is an aluminum pigment covered with a silica film, wherein the water resistant aluminum pigment is formed of an aluminum pigment having an average thickness from 5 nm to 30 nm and a covering film which contains Si and is formed on the surface of the aluminum pigment; and wherein the coverage ratio of the surface of the aluminum pigment by the covering film, calculated from the composition ratio of C, O, Al, and Si detected by XPS measurement at an incident angle of 30°, is in a range from 30% to 90%.

Provided is a surface-treated pigment that is a metallic pigment composed of plate-like particles of which surfaces are treated with an alkoxysilane compound having at least one long-chain alkyl group.
摘要:
Provided is an ink jet printing method of discharging glitter ink, of which glitter pigment is dispersed in water, onto a non-ink-absorption or low-ink-absorption printing medium in an ink jet method. The ink jet printing method includes: a foundation layer formation process of forming a foundation layer by providing resin ink, of which a resin component is dispersed or dissolved in a dispersion medium, onto at least a portion of the printing medium on which the glitter ink is intended to be discharged; and a glitter ink printing process of discharging the glitter ink onto the foundation layer.
摘要:
An image forming apparatus includes a head unit that ejects ink and a control unit that forms a metallic image by causing metallic ink that includes metallic particles to be ejected onto a medium from the head unit are provided, wherein the control unit changes the amount of the metallic ink that is ejected per unit area of the medium based on the gradation values of the pixels that configure the metallic image while causing the metallic image to have a predetermined width or greater.
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.
