Abstract
PURPOSE: To prepare a colored aggregate with excellent color fastness by having a dyestuff or a pigment adsorbed within fine pores of "shirasu" balloon by a resin binder.
CONSTITUTION: In a solution containing a thermosetting or an air-drying resin binder such as an acryl type, a melamine type, or a vinyl type binder, and an org. or an inorg. dyestuff or pigment stable to the resin binder, "shirasu" balloons from which adsorbed moisture is preliminarily removed by heat drying are immersed for 5W10min to adsorb the binder etc. Then the "shirasu" balloons are taken out, excessive impregnated solution is removed by centrifugal separation and heat drying or air drying is carried out to obtain a colored aggregate material of which color does not fade even if the surface thereof is abraded and the initial color tone of a coating or a cement containing said aggregate is not lost when used for a long period.
