摘要:
An ultraviolet crosslinking ink including a radically polymerizable and anionically polymerizable monomer; a photoradical generator; and a photo-base generator. An inkjet recording method including ejecting an ultraviolet crosslinking ink including a radically polymerizable and anionically polymerizable monomer; a photoradical generator; a photo-base generator; and a colorant, toward a surface of a recording material to form an ink image, and irradiating the ink image with ultraviolet light using a light emitting diode.
摘要:
A copolymer contains repeating units represented by the following chemical formulae 1 and 2: In the chemical formulae 1 and 2, R represents a hydrogen atom or a cation; X represents an alkylene group having 2 to 18 carbon atoms; Y represents a single bond, an oxycarbonyl group [(X)—O—CO—(Z)], a carbonyloxy group [(X)—CO—O—(Z)], an ether group (—O—), or an imido group [(X)—N—CO—(—CO—)(Z)]; and Z represents a biphenyl group or a naphthyl group).

Ink includes water, a pigment, an organic solvent including glycol ether, and a surfactant including a silicone-based surfactant and a salt of sulfo succinic acid dialkyl ester. As measured by maximum bubble pressure technique at 23 degrees C., the dynamic surface tension of the ink at 15 msec is not greater than 31 mN/m and the difference between the dynamic surface tension of the ink at 15 msec and the dynamic surface tension of the ink at 1,500 msec is not greater than 4.0 mN/m.
摘要:
There is provided an ink for recording, which contains: a coloring agent; a water-dispersible resin; a wetting agent; a surfactant; and water, wherein a total solid content of the coloring agent and the water-dispersible resin is 10% by mass to 30% with respect to a total mass of the ink, a ratio B/C is 0.1 to 1.6 where B is a solid content of the coloring agent in the ink, and C is a solid content of the water-dispersible resin in the ink, a viscosity of the ink is 5 mPa·s to 20 mPa·s at 25° C., and a surface tension of the ink is 35 mN/m or less.
