Abstract:
The invention relates to a solid pigment preparation comprising a pigment and a dispersant resin, wherein the composition comprises at least 35% by weight of at least one pigment and at most 65% by weight of dispersant resin, calculated on the combined weight of pigment and dispersant resin, wherein the dispersant resin comprises a polymer backbone produced by chain-reaction polymerization having pendent hydrophilic polyalkylene oxide side groups, and wherein the pigment particles within the preparation have average particle sizes in the range of 50 nm to 5,000 nm.
