| titleOfInvention | Dispersing agent for pigment |
| abstract | PURPOSE: To decrease viscosity of a dispersion liquid of pigment of high viscosity, by producing dispersing agents for use in pigment by combining polystyrene sulfonates having weight-average mol.wt. of 5,000W100,000 and sulfonation rate of 60W95%. n CONSTITUTION: Polystyrene is directly sulfonated by the use of sulfonation agents such as sulfuric acid, sulfuric acid anhydride, fuming sulfuric acid, etc. by a normal method, from which unreacted polystyrene is filtered to be separated and the remainder is neutralized by sodium hydroxide, calcium hydroxide, etc. to obtain polystyrene sulfonates having a weight-average molecular weight of 5,000W100,000 and sulfonation rate of 60W95%. By adding the polystyrene sulfonates to dispersion liquids of pigments, particularly, inorganic pigments such as heavy calcium carbonate, kaoline, etc., the viscosity thereof is decreased, in which the quantity of added polystyrene sulfonates is preferably 0.05W1wt.% per inorganic pigments. n COPYRIGHT: (C)1989,JPO&Japio |
