Abstract
Official abstract text for this publication.
A solvent-based ink jet ink composition includes a pigment, a solvent a that is a cyclic ester; and a solvent b with a lower dissolving power of polyvinyl chloride than the solvent a, in which a content of the solvent a is 1.0 to 7.0 mass %, and a content of the solvent b is 10 parts by mass or more to one part by mass of the content of the solvent a.
First claim
Opening claim text (preview).
What is claimed is: 1 . A solvent-based ink jet ink composition comprising: a pigment; a solvent a that is a cyclic ester; and a solvent b with a lower dissolving power of polyvinyl chloride than the solvent a, wherein a content of the solvent a is 1.0 to 7.0 mass %, and a content of the solvent b is 10 parts by mass or more to one part by mass of the content of the solvent a. 2 . The solvent-based ink jet ink composition according to claim 1 , wherein the pigment includes a white pigment. 3 . The solvent-based ink jet ink composition according to claim 1 , further comprising: a glycol monoether solvent, wherein a content of the glycol monoether solvent is 4.0 to 20 mass %. 4 . The solvent-based ink jet ink composition according to claim 1 , wherein the solvent b includes a compound represented by the following formula (1). R 1 O—(R 2 O) m —R 3 Formula (1) (in the formula, R 1 is a hydrogen atom or an alkyl group with 1 to 4 carbon atoms, R 2 is an alkylene group with 2 or carbon atoms, R 3 is an alkyl group with 1 to 4 carbon atoms, and m is an integer of 2 to 4.) 5 . The solvent-based ink jet ink composition according to claim 1 , wherein the solvent b includes a compound b1 with a flash point of 70° C. or less, and a content of the compound b1 is 50 mass % or more to the total amount of the solvent b. 6 . The solvent-based ink jet ink composition according to claim 5 , wherein the content of the compound b1 is 10 parts by mass or more to one part by mass of the content of the solvent a. 7 . The solvent-based ink jet ink composition according to claim 1 , wherein the solvent-based ink jet ink composition is used in an ink jet recording method including attaching in which the solvent-based ink jet ink composition is attached to a recording medium, and the ink jet recording method includes attaching in which an attachment amount in an attachment region of the recording medium is 10 to 70 mg/inch 2 . 8 . The solvent-based ink jet ink composition according to claim 1 , further comprising: water, wherein a content of the water is 3.0 mass % or less. 9 . An ink jet recording method, comprising: attaching the solvent-based ink jet ink composition according to claim 1 to a recording medium. 10 . An ink jet recording method, comprising: attaching the solvent-based ink jet ink composition according to claim 2 to a recording medium. 11 . An ink jet recording method, comprising: attaching the solvent-based ink jet ink composition according to claim 3 to a recording medium. 12 . An ink jet recording method, comprising: attaching the solvent-based ink jet ink composition according to claim 4 to a recording medium. 13 . An ink jet recording method, comprising: attaching the solvent-based ink jet ink composition according to claim 5 to a recording medium. 14 . An ink jet recording method, comprising: attaching the solvent-based ink jet ink composition according to claim 6 to a recording medium. 15 . An ink jet recording method, comprising: attaching the solvent-based ink jet ink composition according to claim 7 to a recording medium. 16 . An ink jet recording method, comprising: attaching the solvent-based ink jet ink composition according to claim 8 to a recording medium.
