PURPOSE:To obtain a soln. of dispersed metallic colloid capable of being concentrated and diluted by mixing 2 kinds of prescribed liqs. with a solvent having compatibility with the liqs. and by evaporating water from the resulting suspension of metallic colloidal particles. CONSTITUTION:A stable suspension is prepared by mixing a soln. of rubber or a rubber-base composition with a suspension of metallic colloidal particles in water or a water-base dispersing medium and a solvent having compatibility with said composition and water. The prepared suspension is heated and/or evacuated with stirring to remove the water by evaporation. Thus, a soln. of uniformly dispersed metallic colloidal particles capable of being concentrated and diluted is obtd. |
