Synthetic example

[0068] Synthesis example: (Synthesis of organic binder)

[0069] Add diethylene glycol monoethyl ether acetate as a solvent and azobisisobutyronitrile as a catalyst to a flask equipped with a thermometer, a stirrer, a dropping funnel, and a reflux condenser, and heat to 80 under a nitrogen atmosphere. ℃, the monomer of methacrylic acid and methyl methacrylate was mixed in the molar ratio of methacrylic acid: 0.4 mol, methyl methacrylate: 0.6 mol, and the monomer was added dropwise over about 2 hours, and then stirred for 1 hour After that, the temperature was increased to 115°C to inactivate it, and a resin solution was obtained. After cooling the resin solution, using tetrabutylammonium bromide as a catalyst, add butyl glycidyl ether: 0.4 mol and the same amount of carboxyl groups of the resulting resin at 95-115°C for 30 hours. Into the reaction, cooling. Furthermore, under the conditions of 95-105°C for 8 hours, the OH group of the obtained resin was subjected to an addition...

Abstract

The invention provides a cataplasm composition containing an inorganic oxide and a roast pattern capable of keeping for a long time as well as inhibiting a viscosity from rising, and not easily bringing out a settling separation of the inorganic oxide with good dispersion. The cataplasm composition comprises the inorganic oxide, a water-soluble dispersant and an organic binding agent. The water-soluble dispersant has an amine value more than 20mgKOH / g and an acid number more than 30mgKOH / g.

Description

Technical field [0001] The present invention relates to the improvement of paste compositions containing inorganic oxides. Background technique [0002] Paste compositions containing inorganic oxides such as black pigments are widely used in applications such as paints, inks, toners, rubber plastics, and electronic materials. [0003] In applications such as electronic materials, in order to be easily mixed with other materials, a paste containing a high concentration of finely divided inorganic oxides such as a black pigment and a low viscosity is particularly required (Patent Documents 1 and 2). [0004] In addition, in recent years, the demand for higher concentrations of paste compositions containing inorganic oxides such as black pigments has been further increased, and there has been an increase in the aging (viscosity) that does not easily cause a rise in viscosity and sedimentation even if the paste composition is stored for a long time. ) Requirements for paste compositions...
