ABSTRACT:
Disclosed is an aqueous dispersion comprising (i) a hydrophobic thermoplastic polymer, (ii) a water-insoluble thermoplastic polymer containing a carboxylic acid salt group bonded to the polymer chain at a concentration of 0.1 to 5 milliequivalents as --COO-- per gram of the polymer, (iii) water and, if necesssary, (iv) at least one member selected from the group consisting of anionic surface active agents, nonionic surface active agents, organic solvents and oils, said aqueous dispersion being apparently solid and having a water content of 0.5 to 3% by weight and an electric resistance lower than 10.sup.6 .OMEGA.-cm and also having such a property that when water is added to the dispersion, solids are uniformly dispersed as fine particles in the aqueous phase.
