摘要： Improved reactive color developing substrates for manifold copy systems are produced by controlled acid treatment of smectite clay minerals, followed by severe attrition grinding to produce an aqueous colloidal suspension of the acid treated smectite. Thereupon, the colloidalized acid treated smectite is combined with an aqueous suspension of talc, thoroughly blended and co-precipitated by the addition of appropriate flocculants such as aluminum sulfate.
