Provided is an aqueous dispersion of colored particles suitable for colorants for writing instrument inks, inkjet inks, painting materials, aqueous coatings, and the like. The aqueous dispersion of colored particles includes a polymer having at least a unit of a monomer derived from a dye having a polymerizable unsaturated group. The monomer derived from the dye is preferably derived from the compound represented by General Formula (1) below:

##STR00001##

where Dye represents a dye residue, R.sub.1 represents a hydrogen atom or a methyl group,
Y.sub.2 represents O or NR.sub.10, where R.sub.10 represents a hydrogen atom or an alkyl group,
A.sub.1 represents an alkylene group which is unsubstituted or substituted by at least one group selected from OCO, COO, NHCONH, and the like in the chain thereof and/or at the terminal thereof, and/or a hydroxy group.

The present specification relates to an ink composition including: a compound represented by Formula 1; and a solvent represented by the Formula 2, and a method for manufacturing an organic light emitting device formed by using the ink composition.

A thermal inkjet ink composition includes cellulose nanocrystals (CNCs). The cellulose nanocrystals are present in the thermal inkjet ink composition in an amount ranging from 0.5 wt % up to 3.5 wt %, based on a total weight of the thermal inkjet ink composition. The thermal inkjet ink composition further includes a sugar alcohol present in an amount ranging from 3 wt % up to about 8 wt % based on the total weight of the thermal inkjet ink composition, an organic salt present in an amount ranging from about 0.05 wt % to about 0.5 wt % based on the total weight of the thermal inkjet ink composition, a pigment, a polar solvent, and a balance of water.
