Abstract
An ink composition in which particles of a functional substance comprising a dye or a pigment included in polymer micelles comprising a block polymer are dispersed in a solvent, wherein the particles have an average particle size of not more than 200 nm and a particle size distribution (index of dispersion degree μ/G2) of not more than 0.1, a method of forming an image and an image forming apparatus using the same are provided. The main component of the polymer micelle is an amphiphilic block polymer.
Claims16
A composition in which a functional substance is dispersed,
- wherein the functional substance and a block polymer are dispersed in a solvent in the form of particles, and
- the particles have an average particle size of not more than 70 nm and a particle size distribution represented by an index of dispersion degree μ/G2 of not more than 0.2.
A method of forming an image by applying ink on a recording medium,
- wherein the ink is a composition in which a functional substance is dispersed, wherein the functional substance and a block polymer are dispersed in a solvent in a form of integrated particles, and
- the particles have an average particle size of not more than 70 nm and a particle size distribution represented by an index of dispersion degree μG2 of not more than 0.2.
A recording medium on which an image is formed by applying an ink,
- wherein the ink is a composition in which a functional substance is dispersed, wherein the functional substance and a block polymer are dispersed in a solvent in a form of integrated particles, the particles have an average particle size of not more than 70 nm and a particle size distribution represented by an index of dispersion degree μ/G2 of not more than 0.2, and the recording medium has, on its surface, a stimulating substance which stimulates the ink.
