摘要：
A pigment dispersion useful for forming coating compositions containing dispersed pigment, a carrier liquid and an AB-block polymer dispersant (binder);the AB block polymer has a number average molecular weight of about 5,000-20,000 and contains 20-80% by weight of a polymeric A segment and correspondingly 80-20% by weight of a polymeric B segment; whereinthe polymeric A segment of the block polymer is of polymerized glycidyl (meth)acrylate monomers reacted with an acid from the group of aromatic carboxylic acids or aliphatic carboxylic acids; andthe B segment is of polymerized alkyl (meth)acrylate monomers having 1-12 carbon atoms in the alkyl group, hydroxy alkyl (meth)acrylate monomers having about 1-4 carbon atoms in the alkyl group; andwherein the weight ratio of pigment to binder in the dispersion is about 1/100-200/100.
