First claim
Opening claim text (preview).
The invention claimed is: 1. An ink composition for water-based inks comprising an emulsion and an organic solvent, said emulsion comprising an emulsion particle containing a polymer component having a glass transition temperature of 55° C. or more and a polymer component having a glass transition temperature of less than 55° C., and said emulsion particle having an acid value derived from carboxyl groups of 0 to 6, wherein said polymer components contained in said emulsion particle have been obtained by emulsion-polymerization of monomer components, said monomer components comprising a monomer component selected from the group consisting of piperidine group-containing monomers, nitrogen atom-containing monomers, and additional-polymerizable oxazolines, and wherein said organic solvent comprises an organic solvent selected from the group consisting of propylene glycol, diethylene glycol, triethylene glycol, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, diethylene glycol monoisopropyl ether, diethylene glycol monobutyl ether, and diethylene glycol monoisobutyl ether. 2. The ink composition for water-based inks according to claim 1 , wherein said emulsion particle has a core-shell structure composed of a shell portion of the outermost layer and a core portion inside said shell portion, and wherein said core portion contains said polymer component having said glass transition temperature of 55° C. or more, and said shell portion contains said polymer component having said glass transition temperature of less than 55° C. 3. The ink composition for water-based inks according to claim 2 , wherein said shell portion contains a polymer component having a glass transition temperature of 25° C. or less. 4. The ink composition for water-based inks according to claim 2 , wherein said core portion contains a polymer component having a glass transition temperature of 90° C. or more. 5. The ink composition for water-based inks according to claim 1 , wherein said monomer components comprises a monomer component selected from the group consisting of piperidine group-containing monomers and additional-polymerizable oxazolines.
