Abstract
Official abstract text for this publication.
A cleaning fluid used in an ink-jet printer ejecting an aqueous ink-jet ink containing a pigment and an alkali-soluble resin, to clean a portion of the ink-jet printer to which the ejected aqueous ink-jet ink is adherent. The cleaning fluid includes a surfactant, an antiseptic, and water. The surfactant is a compound having a polyoxyalkylene skeleton and an HLB of 9-20, and the antiseptic includes a compound having a hydantoin skeleton, the content of which is 0.05-0.3 mass %. The cleaning fluid does not attack nozzle plates made of silicone and has satisfactory storage stability, antiseptic effect, and ability to remove aqueous ink-jet inks.
First claim
Opening claim text (preview).
What is claimed is: 1. A cleaning fluid used in an inkjet printer that ejects an aqueous inkjet ink containing a pigment and an alkali-soluble resin, and used for cleaning a portion of the inkjet printer to which the aqueous inkjet ink to be ejected adheres, the cleaning fluid comprising: a surfactant; an antiseptic; and water, wherein the surfactant is a compound having a polyoxyalkylene skeleton and having an HLB of 9 to 20, the antiseptic contains a compound having a hydantoin skeleton, and a proportion of the compound having a hydantoin skeleton in the cleaning fluid is 0.05 to 0.3 mass %. 2. The cleaning fluid according to claim 1 , further comprising one or more types of moisturizers selected from the group consisting of a polyalkylene glycol, an alkylene glycol, and glycerin. 3. The cleaning fluid according to claim 1 , further comprising a pH adjuster. 4. The cleaning fluid according to claim 1 , wherein the compound having a hydantoin skeleton is 1,3-bis(2-hydroxyethyl)-5,5-dimethyl-2,4-imidazolidinedione. 5. The cleaning fluid according to claim 1 , further comprising, as the antiseptic, an antiseptic other than the compound having a hydantoin skeleton. 6. An ink set comprising: the cleaning fluid according to claim 1 ; and an aqueous inkjet ink containing a pigment and an alkali-soluble resin. 7. A cleaning method comprising, in an inkjet printer that ejects an aqueous inkjet ink containing a pigment and an alkali-soluble resin, supplying the cleaning fluid according to claim 1 to a portion to which the aqueous inkjet ink to be ejected adheres.
