Electrostatic latent image developing toner
An electrostatic latent image developing toner includes a plurality of toner particles each having: a sea-like domain substantially formed from a plurality of resins including at least a polyester resin containing an alcohol component having a carbon number of 2-6; and a plurality of island-like domains distributed in an island-like pattern in the sea-like domain. The island-like domains are substantially formed from a resin containing a nigrosine pigment. A dispersion diameter of the island-like domains is 0.1-1.0 m. The polyester resin containing the alcohol component having a carbon number of 2-6 is contained in the sea-like domain in an amount of 5-50% by mass relative to a total amount of constituent resins (the plurality of resins). A ratio of an SP value of the resins forming the sea-like domain to an SP value of the resin forming the island-like domain is no greater than 0.98 or at least 1.20.
MIXTURE, TONER, AND DISPERSION
A mixture contains a compound having a specific structure and acting as a dye and a compound having a specific structure and acting as an ultraviolet light absorbent.
Compound, pigment dispersing agent, pigment composition, pigment dispersion and toner containing said compound
Provided is a compound that improves dispersibility of a pigment in a non-water-soluble solvent, and a pigment dispersing agent, a pigment composition, a pigment dispersion and a toner that use that compound. The present invention relates to a compound in which a polymer and a monoazo compound having a specific structure are bonded. The present invention further relates to a pigment dispersing agent, a pigment composition, a pigment dispersion and a toner containing that compound.
