Abstract
Official abstract text for this publication.
An object is to provide an aqueous inkjet ink composition offering excellent high-gap discharge stability, antifouling property, adhesion, drying property, abrasion resistance, discharge stability, and preservation stability, even when printed on nonabsorbent media. As a solution, an aqueous inkjet ink composition is provided that contains a pigment, an alkali-soluble resin, a polyolefin resin emulsion, a basic compound, an aqueous medium, and a surfactant, wherein the glass transition temperature of the alkali-soluble resin is 40 to 100° C., the average grain size of the polyolefin resin emulsion is 5 to 300 nm, the solids content of the polyolefin resin emulsion is 0.5 to 5.0 percent by mass in the aqueous inkjet ink composition, and the surfactant contains at least an acetylenediol-based surfactant.
First claim
Opening claim text (preview).
What is claimed is: 1. An aqueous inkjet ink composition containing a pigment, an alkali-soluble resin, a polyolefin resin emulsion, a basic compound, an aqueous medium, and a surfactant, wherein a glass transition temperature of the alkali-soluble resin is 70° C. to 95° C., an average grain size of the polyolefin resin emulsion is 5 to 300 nm, a solids content of the polyolefin resin emulsion is 0.5 to 5.0 percent by mass in the aqueous inkjet ink composition, and the surfactant contains at least an acetylenediol-based surfactant. 2. The aqueous inkjet ink composition according to claim 1 , wherein a content of the pigment is 2.0 to 6.0 percent by mass in the aqueous inkjet ink composition. 3. The aqueous inkjet ink composition according to claim 1 , wherein the polyolefin resin emulsion is a nonionic polyalkylene wax emulsion. 4. The aqueous inkjet ink composition according to claim 1 , wherein a content of the surfactant is 0.1 to 5.0 percent by mass in the aqueous inkjet ink composition. 5. The aqueous inkjet ink composition according to claim 2 , wherein the polyolefin resin emulsion is a nonionic polyalkylene wax emulsion. 6. The aqueous inkjet ink composition according to claim 2 , wherein a content of the surfactant is 0.1 to 5.0 percent by mass in the aqueous inkjet ink composition. 7. The aqueous inkjet ink composition according to claim 3 , wherein a content of the surfactant is 0.1 to 5.0 percent by mass in the aqueous inkjet ink composition. 8. The aqueous inkjet ink composition according to claim 5 , wherein a content of the surfactant is 0.1 to 5.0 percent by mass in the aqueous inkjet ink composition.
