Title:
ABCブロックポリマー分散剤を含む顔料分散液
Document Type and Number:
Japanese Patent JP3590382
Kind Code:
B2
Abstract:
A pigment dispersion useful for forming coating compositions containing dispersed pigment, a non-aqueous carrier liquid and an ABC-block polymer dispersant (binder); whereinthe ABC block polymer has a number average molecular weight of about 5,000-20,000 and contains a polymeric A segment, a polymeric B segment and a polymeric C segment; whereinthe polymeric A segment of the block polymer is of polymerized monomers selected from the following group: alkyl (meth)acrylate monomers having 1-12 carbon atoms in the alkyl group, aryl (meth)acrylate monomers, cyclo alkyl (meth)acrylate monomers or mixtures of any of the above;the polymeric B segment of the block polymer is of polymerized alkyl amino alkyl (meth)acrylate monomers having 1-4 carbon atoms in the alkyl group quaternized with an alkylating agent; andthe polymeric C segment of the block polymer is of polymerized monomers of hydroxy alkyl (meth)acrylate having 1-4 carbon atoms in the alkyl group and monomers selected from the following group: alkyl (meth)acrylate monomers having 1-12 carbon atoms in the alkyl group, aryl (meth)acrylate monomers, cycloalkyl (meth)acrylate monomers and any mixtures thereof and optionally contains polymerized monomers of glycidyl (meth)acrylate or polyalkylene glycol (meth)acrylate; wherein the weight ratio of pigment to binder in the dispersion is about 1/100-200/100; pigment dispersions of a CBA block polymer where the C,B and A segments are as described above also are part of this invention.
