Abstract
Official abstract text for this publication.
There is provided a non-aqueous ink jet ink composition, including a pigment, a non-aqueous solvent, and a surfactant, in which the ink composition contains an acetylene glycol-based surfactant having a HLB value of 1.0 to 6.0 as the surfactant.
First claim
Opening claim text (preview).
What is claimed is: 1 . A non-aqueous ink jet ink composition, comprising: a pigment; a non-aqueous solvent; and a surfactant, wherein the ink composition contains an acetylene glycol-based surfactant having a HLB value of 1.0 to 6.0 as the surfactant. 2 . The non-aqueous ink jet ink composition according to claim 1 , wherein the non-aqueous solvent contains a non-polar organic solvent having a 50% distillation point of 280° C. or lower and a polar organic solvent having a 50% distillation point of 300° C. or higher, and the total content of the non-polar organic solvent and the polar organic solvent in the non-aqueous solvent is 60.0 mass % or more. 3 . The non-aqueous ink jet ink composition according to claim 1 , wherein, in the shear viscosity measurement of the ink composition at 20° C. by a rheometer, the difference in shear viscosity of the ink composition between a shear rate of 20 [1/s] and a shear rate of 50 [1/s] is 0.60 [mPa·s] or less. 4 . The non-aqueous ink jet ink composition according to claim 1 , wherein the ratio of the content of the pigment to the content of the acetylene glycol-based surfactant ([the content of the pigment]/[the content of the acetylene glycol-based surfactant]) in the ink composition is 0.1 or more and less than 3.0. 5 . The non-aqueous ink jet ink composition according to claim 1 , wherein the content of the pigment is 5.0 mass % to 15.0 mass % with respect to the total mass of the ink composition. 6 . The non-aqueous ink jet ink composition according to claim 2 , wherein the non-polar organic solvent contains at least one selected from the group consisting of aliphatic hydrocarbons, alicyclic hydrocarbons, and aromatic hydrocarbons. 7 . The non-aqueous ink jet ink composition according to claim 2 , wherein the polar organic solvent contains at least one selected from the group consisting of soybean oil methyl, soybean oil isobutyl, methyl oleate, ethyl oleate, isostearyl alcohol, oleyl alcohol, isopalmitic acid, isostearic acid, isoarachic acid, isohexacosanoic acid, isopropyl isostearate, methyl linoleate, isobutyl linoleate, and tall oil isobutyl.
