Title:
DISPERSION LIQUID, INK COMPOSITION FOR INK JET RECORDING, AND DISPERSION RESIN
Document Type and Number:
Japanese Patent JP2022052812
Kind Code:
A
Abstract:
To provide a dispersion liquid or the like that enable a solidified coloring material to be easily re-dispersed and allows improved stability during re-ejection after drying.SOLUTION: A dispersion liquid includes water, a coloring material, and a dispersion resin that disperses the coloring material. The dispersion resin has a constituent unit A containing a hydrophobic monomer, a constituent unit B containing a hydrophilic acrylic acid monomer, and a constituent unit C containing a hydrophilic vinyl monomer having a sulfonate group, and a weight-average molecular weight of the dispersion resin is 10,000 to 100,000. A content of the constituent unit A is 60 mol% or more relative to a total amount of the dispersion resin.SELECTED DRAWING: None
