Abstract
Official abstract text for this publication.
An ink set including an aqueous inkjet ink composition and a primer composition. The aqueous inkjet ink composition contains a pigment, an alkali-soluble resin, a resin emulsion, a surfactant, a water-soluble solvent, and water; the resin emulsion contains a polyurethane resin emulsion and/or a polyolefin resin emulsion; the surfactant contains an alkyl sulfonate and/or a polyoxyethylene alkyl ether sulfate; the aqueous inkjet ink composition has a content of the alkyl sulfonate and/or the polyoxyethylene alkyl ether sulfate of 0.05% by mass or more and 0.5% by mass or less; and the primer composition contains an aggregation accelerator that accelerates aggregation of the aqueous inkjet ink composition. The ink set provides a printed matter having good print image quality and excellent abrasion resistance, and has good storage stability and ejection stability.
First claim
Opening claim text (preview).
The invention claimed is: 1. An ink set comprising: an aqueous inkjet ink composition; and a primer composition, wherein the aqueous inkjet ink composition contains a pigment, an alkali-soluble resin which is an acrylic copolymer resin, a resin emulsion, a surfactant, a water-soluble solvent, and water, the resin emulsion contains a polyurethane resin emulsion and/or a polyolefin resin emulsion, the surfactant contains an alkyl sulfonate and/or a polyoxyethylene alkyl ether sulfate, the aqueous inkjet ink composition has a content of the alkyl sulfonate and/or the polyoxyethylene alkyl ether sulfate of 0.05% by mass or more and 0.5% by mass or less, and the primer composition contains an aggregation accelerator that accelerates aggregation of the aqueous inkjet ink composition. 2. The ink set according to claim 1 , wherein the aqueous inkjet ink composition has a solid content of the polyurethane resin emulsion and/or the polyolefin resin emulsion of 1% by mass or more and 10% by mass or less. 3. A printed matter obtained by performing printing using the ink set according to claim 1 . 4. An image formation method using the ink set according to claim 1 .
