摘要:
A pigment dispersion is provided that includes a pigment, a pigment dispersant, a polymer dispersion stabilizer and water, wherein the polymer dispersion stabilizer is an alpha-olefin/maleic anhydride copolymer expressed by the formula (1) below. A recording ink is also provided that includes the pigment dispersion, a surfactant, a water-dispersible resin, a humectant and water. In the structural formula (1), R represents an alkyl group and n is an integer of 30 to 100.
摘要:
A recording ink containing a pigment dispersion, a surfactant, a water-dispersible resin, a humectant and water. The pigment dispersion contains a pigment dispersant, which is an anionic surfactant or a nonionic surfactant having an HLB value of 10 to 20. The pigment dispersion also contains a polymer dispersion stabilizer, which is an alpha-olefin/maleic anhydride copolymer expressed by the formula (1) below, where R is an alkyl group having 6 to 25 carbon atoms, and where the mass average molecular weight of the copolymer is 5000 to 20000. An ink cartridge, an inkjet recording method, an inkjet recording apparatus, and an ink recorded matter, each employing the recording ink, are also provided.
