Title:
POLYURETHANE-BASED PIGMENT DISPERSANT WHICH CONTAINS REACTIVE DOUBLE BOND
Document Type and Number:
Japanese Patent JP2013010963
Kind Code:
A
Abstract:

To provide a polymeric urethane dispersant with at least one reactive carbon-carbon double bond on average per molecule.

The polymeric urethane dispersants with solubilizing polymer chains and with reactive carbon-carbon double bonds are described. The reactive double bonds facilitate molecular weight build-up of the dispersant on dispersed particles (enhancing colloidal stability) or enhance the ability of the dispersants to be crosslinked into a matrix material. In the first embodiment, once the dispersion of particles has been made, the dispersants may be crosslinked with a suitable crosslinking agent (e.g. polyamine or via free radicals) to immobilize them onto the particle surface.
