Abstract

Official abstract text for this publication.

An ink composition at least contains a compound A having a hydroxy group and a compound B having an aldehyde group as polyoxyalkylene alkyl ether surfactants. The mass ratio of the compound B to the compound A is 0.5×10−4 to 30×10−4.

First claim

Opening claim text (preview).

What is claimed is: 1. An ink composition at least comprising: a compound A and a compound B as polyoxyalkylene alkyl ether surfactants, wherein the compound A has a hydroxy group and is represented by Formula (1), and the compound B has an aldehyde group and is represented by Formula (2): R—O—(C 2 H 4 O) v (C 3 H 6 O) w (C 2 H 4 O) x (C 3 H 6 O) y —(CH 2 ) z —CH 2 —OH  (1) R—O—(C 2 H 4 O) v (C 3 H 6 O) w (C 2 H 4 O) x (C 3 H 6 O) y —(CH 2 ) z —COH  (2) in Formulae (1) and (2), each R independently represents an alkyl group having 1 to 20 carbon atoms, each v independently represents 1 to 20, each w independently represents 0 to 20, each x independently represents 0 to 20, each y independently represents 0 to 20, and each z independently represents 1 to 2; and a relationship of 5≤v+w+x+y+z≤30 is satisfied; and the mass ratio of the compound B to the compound A is 0.5×10 −4 to 30×10 −4 . 2. The ink composition according to claim 1 , wherein the content of the compound B is 1 to 100 ppm based on the total amount of the ink composition. 3. The ink composition according to claim 1 , wherein the content of the polyoxyalkylene alkyl ether surfactants is 0.2 to 5.0 mass % based on the total amount of the ink composition. 4. The ink composition according to claim 1 , further comprising water, a penetration solvent, a coloring material, and at least one selected from the group consisting of acetylene glycol surfactants, polysiloxane surfactants, and fluorine surfactants. 5. A recording method comprising: discharging the ink composition according to claim 1 with an ink jet system; and allowing the ink composition to adhere to a recording medium.
