摘要： An anti-settling agent composition for aqueous coating materials, comprising [A] a polyamide which is obtained by polymerizing a diamine having 2-12 carbon atoms and an excess amount, relative to diamine, of either a dicarboxylic acid having 4-36 carbon atoms or a mixture of a dicarboxylic acid having 4-36 carbon atoms and a monocarboxylic acid having 2-22 carbon atoms, and [B] a hydrophobic organic compound which is a hydrocarbon modified with 1-3 hydroxyl groups and/or carboxyl groups and having 10-54 carbon atoms, and which has a freezing point of 20° C. or less or does not have a definite freezing point. The anti-settling agent is able to be easily dispersed in a coating material even if directly added into the coating material without being diluted when added into the coating material, and which imparts the coating material with excellent anti-settling properties.

摘要： Provided is a novel layer migration control agent that is added to a paint composition when forming a multilayer coating film on a coating object by curing a prime coating film and a top coating film at the same time, the agent making it possible to control layer migration of the two coating films and obtain the multilayer coating film with satisfactory finish appearance. The layer migration control agent is a copolymer obtained by copolymerization of a monomer mixture including 5% by weight to 90% by weight of a polymerizable unsaturated monomer including an ether group and 10% by weight to 95% by weight of a polymerizable unsaturated monomer having a hydrophobic group having 1 to 22 carbon atoms, the copolymer having a weight average molecular weight of 1000 to 100,000.

摘要： This invention provides a viscosity modifier for high concentration dispersion of inorganic fine particles which can reduce, by giving excellent viscosity modifying function to a high concentration dispersion of inorganic fine particles (e.g., printing ink composition, functional paste composition or paint composition, of high concentration dispersion of inorganic fine particles), the occurrence of inconvenience in a printing step or coating step for the manufacture of components or substrates, and also provides a high concentration dispersion of inorganic fine particles which contains said viscosity modifier. This viscosity modifier comprises, as a main component, a reaction product having 2 to 20 phosphate groups or carboxyl groups in molecular structure, which reaction product is produced from a reaction between a polyol having two to six hydroxyl groups and a phosphate group-introducing material or a carboxyl group-introducing material at a molar ratio of hydroxyl group to phosphate group-introducing material or carboxyl group-introducing material of 3:1 to 1:1.
