Abstract
Official abstract text for this publication.
The present invention provides a cleaning liquid that can remove even white ink after being fixed and solve ejection failure of inkjet printers. Provided is a cleaning liquid containing: a first surfactant, a second surfactant, and a basic compound, the first surfactant including an amphoteric surfactant, the second surfactant including at least one of an anionic surfactant that is a sulfonate or a nonionic surfactant that has a branched structure and has an HLB of 7 to 14.
First claim
Opening claim text (preview).
1 . A cleaning liquid comprising: a first surfactant; a second surfactant; and a basic compound, the first surfactant including an amphoteric surfactant, the second surfactant including at least one of an anionic surfactant that is a sulfonate or a nonionic surfactant that has a branched structure and has an HLB of 7 to 14. 2 . The cleaning liquid according to claim 1 , wherein the first surfactant includes at least one selected from the group consisting of lauryldimethylamine oxide, lauryl dimethylaminoacetic acid betaine, and 2-alkyl-N-carboxymethyl-N-hydroxyethylimidazolinium betaine. 3 . The cleaning liquid according to claim 1 , wherein the first surfactant is contained in an amount of 0.1% to 3% by mass based on a total amount of the cleaning liquid. 4 . The cleaning liquid according to claim 1 , wherein the second surfactant includes at least one of sodium alkyl sulfate sulfonate or polyoxyethylene isotridecyl ether (5EO). 5 . The cleaning liquid according to claim 1 , wherein the second surfactant is contained in an amount of 0.1% to 3% by mass based on a total amount of the cleaning liquid. 6 . The cleaning liquid according to claim 1 , wherein the basic compound includes at least one of sodium hydroxide or potassium hydroxide. 7 . The cleaning liquid according to claim 1 , having a pH of 9 to 12. 8 . The cleaning liquid according to claim 1 , further comprising a preservative and water. 9 . The cleaning liquid according to claim 1 , wherein the cleaning liquid is for use in removing an aqueous inkjet printing ink composition, and the aqueous inkjet printing ink composition contains a pigment and an alkali soluble resin having an acid group in a molecule. 10 . The cleaning liquid according to claim 1 , wherein the pigment is contained in an amount of 3% to 12% by mass based on a total amount of the aqueous inkjet printing ink composition, and the alkali soluble resin having an acid group in a molecule has an acid value of 100 to 200 mgKOH/g.
