Document Type and Number:

Japanese Patent JP2003064139

Kind Code:

A

Abstract:

To obtain a block polymer useful for producing a pigment paste and excellent in pigment dispersibility.

The block polymer consists of a solvent-soluble block (A) having 1000-100000 number average molecular weight and a halogen on its terminal and a pigment-absorbing block (B) having an N-containing functional group and the mass ratio of the block (A) and the block (B) is 40-99.5:60-0.5. A pigment paste comprising a resin for dispersing pigments and the pigment and a color paint composition comprising the pigment paste and a binder resin are disclosed.
