Abstract
Provided is a pigment distribution system. The pigment distribution system includes a pigment encapsulated by physically adsorbing a diblock copolymer to the pigment. The diblock copolymer is represented by Formula 1 below: AmBn <Formula 1> where -A- denotes a hydrophilic monomer, -B- denotes a hydrophobic monomer, m denotes an integer ranging from 1 to 10, and n denotes an integer ranging from 3 to 30, wherein hydrophilic monomers of neighboring diblock copolymer chains are crosslinked using a crosslinker.

A pigment distribution system comprising a pigment encapsulated by physically adsorbing a diblock copolymer to the pigment, the diblock copolymer being represented by Formula 1 below:
- AmBn <Formula 1>
- where -A- denotes a hydrophilic monomer, -B- denotes a hydrophobic monomer, m denotes an integer ranging from 1 to 10, and n denotes an integer ranging from 3 to 30,
- wherein hydrophilic monomers of neighboring diblock copolymer chains are crosslinked using a crosslinker.
An ink composition for fabricating a color filter, the ink composition comprising:
- a pigment encapsulated by physically adsorbing a diblock copolymer to the pigment, the diblock copolymer being represented by Formula 1 below:
- AmBn <Formula 1>
- where -A- denotes a hydrophilic monomer, -B- denotes a hydrophobic monomer, m denotes an integer ranging from 1 to 10, and n denotes an integer ranging from 3 to 30,
- wherein hydrophilic monomers of neighboring diblock copolymer chains are crosslinked using a crosslinker.
A method of encapsulating a pigment, comprising:
- mixing a pigment, a dispersant having crosslinking groups, and a solvent so as to encapsulate the pigment with the dispersant;
- and
- adding a crosslinker to the mixture of the pigment, the dispersant, and the solvent so as to crosslink the crosslinking groups of the dispersant
