Abstract
A recording method for discharging, onto the surface of a substrate, an inkjet ink composition containing an organic solvent by using an inkjet head provided with constituent members bonded by a cured product of an adhesive, the organic solvent containing the following organic solvent (a). Organic solvent (a): at least one substance selected from the group consisting of alkylamide-based solvents (a1), cyclic amide-based solvents (a2), and lactone-based solvents (a3).
Claims15
A recording method comprising ejecting an organic solvent-containing inkjet ink composition onto a surface of a substrate from an inkjet head comprising components bonded together with a cured adhesive material,
- the organic solvent comprising an organic solvent (a),
- wherein the organic solvent (a) is at least one selected from the group consisting of:
- an alkylamide solvent (a1) that is represented by formula (1)
- wherein in formula (1), R1 represents hydrogen or an alkyl group having from one or more to four or less carbon atoms, and R2 represents an alkyl group having from two or more to four or less carbon atoms,
- a cyclic amide solvent (a2), wherein the cyclic amide solvent (a2) is represented by formula (2):
- where R3 represents an alkylene group having from four or more to five or less carbon atoms, and R4 represents hydrogen, an alkyl group having from one or more to two or less carbon atoms, or an unsaturated hydrocarbon group, and
- a seven-membered ring lactone solvent (a3),
- wherein the ink composition has a water content of 5.0 mass % or less based on the total mass of the ink composition, and
- wherein the ink composition is not an active energy ray-curable ink composition.
A method for producing a recorded product, the method comprising ejecting an organic solvent-containing inkjet ink composition onto a surface of a substrate from an inkjet head comprising components bonded together with a cured adhesive material,
- the organic solvent comprising an organic solvent (a),
- wherein the organic solvent (a) is at least one selected from the group consisting of:
- an alkylamide solvent (a1) that is represented by formula (1)
- wherein in formula (1), R1 represents hydrogen or an alkyl group having from one or more to four or less carbon atoms, and R2 represents an alkyl group having from two or more to four or less carbon atoms,
- a cyclic amide solvent (a2), wherein the cyclic amide solvent (a2) is represented by formula (2):
- where R3 represents an alkylene group having from four or more to five or less carbon atoms, and R4 represents hydrogen, an alkyl group having from one or more to two or less carbon atoms, or an unsaturated hydrocarbon group, and
- a seven-membered ring lactone solvent (a3),
- wherein the ink composition has a water content of 5.0 mass % or less based on the total mass of the ink composition, and
- wherein the ink composition is not an active energy ray-curable ink composition.
An inkjet ink composition to be ejected onto a surface of a substrate from an inkjet head comprising components bonded together with a cured adhesive material,

- wherein in formula (1), R1 represents hydrogen or an alkyl group having from one or more to four or less carbon atoms, and R2 represents an alkyl group having from two or more to four or less carbon atoms,
- a cyclic amide solvent (a2), wherein the cyclic amide solvent (a2) is represented by formula (2):
- where R3 represents an alkylene group having from four or more to five or less carbon atoms, and R4 represents hydrogen, an alkyl group having from one or more to two or less carbon atoms, or an unsaturated hydrocarbon group, and
- a seven-membered ring lactone solvent (a3),
- wherein the ink composition has a water content of 5.0 mass % or less based on the total mass of the ink composition, and
- wherein the ink composition is not an active energy ray-curable ink composition.
