Abstract
A plasticizer which is in a solid state at ordinary temperature and a pigment are added to and mixed with a coating base which consists of particulate hydroxypropyl methyl cellulose and/or methyl cellulose having an average particle size ranging from 200 to 1000 .mu.m and whose content of particles having a particle size of not more than 75 .mu.m is not more than 30% by weight. The resulting mixture is heated to a temperature of not less than the solidification point of the plasticizer to give a rapidly soluble coating composition. If the plasticizer is in a liquid state at ordinary temperature, a powdery pigment is added to and mixed with the foregoing coating base while spraying the liquid plasticizer on the resulting mixture to give a rapidly soluble coating composition.
