ABSTRACT:
Encapsulation pigments comprising chromophoric particles embedded in glaze-stable casings are prepared by means of calcination from the appropriate initial products. High yields and strong color intensities are obtained if the chromophoric substance or its initial compounds are bound in and/or to a zeolite and are calcined in this form with the remaining constituents.
