Abstract

PURPOSE: To make simple indentification of the end of curing of a mold possible from the change in color by adding a basic dye to a phosphate type mold material and making combination use of carboxylic acids.
CONSTITUTION: A mold material of which the amt. of addition of a basic dye to a phosphate type mold material is 0.0001W0.004pts.wt. basing on 100pts.wt. mold material. It is the mold material wherein carboxylic acids are used in combination at an addition amt. of ≤1pt.wt. basing on 100pts.wt. mold material. The change in color varies with the kinds, amts. and colors of the used basid dyes; in general, if kneading is started, the material forms a pale color of said dye, and remains as it is or cause tone reduction for a while, but as curing progresses, the color of said dye is darkened and the curing (reaction) completes.
