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 the so-called agent imparting the distinctness of image, namely, an additive for an aqueous coating material that can improve the distinctness of image of the coating film of any glossy aqueous coating material in order to prevent the white blurring phenomenon, which is caused by diffuse reflection of light, to a degree that could not be previously achieved, by increasing the dispersivity of a carbon black or an organic pigment in a coating material resin. Catecholic polymer black microparticles that exhibit an angle-independent structural color are used as the agent imparting the distinctness of image.

摘要： An object of the present invention is to provide a readily thermally degradable resin binder that is an organic resin binder for use as a binder component in a high-concentration inorganic microparticle dispersion, and that enables firing in a firing process to be carried out at lower temperatures and can inhibit the production of carbon residues, while maintaining the printing characteristics. This object can be achieved by a mixture formed of a specific (meth)acrylic resin and an ethyl cellulose resin in a weight ratio of 5:95 to 50:50. This specific (meth)acrylic resin is a (meth)acrylic polymer having a weight-average molecular weight of 1,000 to 250,000 and having a monomer unit given by the following general formula (1) [in the formula, R1 represents hydrogen or a methyl group and R2 represents hydrogen or a C1-12 straight-chain hydrocarbon group, branched-chain hydrocarbon group or hydroxyl group-bearing hydrocarbon group, or a polyalkylene oxide-containing group].
