Document Type and Number:
Japanese Patent JP2007169308
Kind Code:
A
Abstract:
To provide a pigment dispersion in which the monomers do not polymerize during the dispersion process without using a polymerization inhibitor and an organic solvent causing no polymerization, its manufacturing process and a photo-curable ink composition using the pigment dispersion.
The pigment dispersion contains at least a colorant, a dispersant and a polymerizable compound and does not practically contain a polymerization inhibitor. The polymerizable compound is an N-vinyl formamide.
