PURPOSE: To provide an aqueous dispersant excellent in low temperature adhesiveness and transparency by introducing therein α,β-unsaturated carboxylic acid, its alkyl ester and polyalkylene glycol methacrylate. n CONSTITUTION: As dispersing agents for use in the preparation of an aqueous dispersant for the thermoplastic substances such as polyethylene wax and rosin derivative, α,β-unsaturated carboxylic acid of 18-50wt.%, the alkyl ester of α,β-unsaturated carboxylic acid of 5-50wt.% and polyalkylene glycol methacrylate of 20-75wt.% as a third component are introduced into said aqueous dispersant. The copolymerization of the third component with the first and second components decreases the melt viscosity of the dispersing agents and imparts a low temperature adhesiveness and transparency to the aqueous dispersant. n COPYRIGHT: (C)1990,JPO&Japio |
