Beschreibung
Zusammenfassung:	PURPOSE:To make the rate of reaction and the dissolving velocity of a core substance small by coating a substance blended with wax having >=40 deg.C m.p. and higher alcohol on the core substance showing the reactivity and the dissolubility with water or acid and alkali aq. solns. CONSTITUTION:One or more kinds of substances selected from among natural/ synthesized wax having >=40 deg.C m.p., higher alcohol, fatty acid amide, fatty acid ester and fatty acid are melted. A core substance showing the reactivity and the dissolubility with water or acid and alkali aq. solns. is dispersed in the melted soln. and also one or more kinds of a surface-active agent and the hydrophilic fine powder are added in accordance with the necessity. Then the reactivity or the dissolubility with water or acid and alkali aq. solns. is retarded by spraying it with the use of an atomizer and cooling it. Still more about 40-200pts.wt. coating substance is preferable for 100pts.wt. core substance.
