Abstract
The present invention relates to a casting resin based on curable acrylic and/or methacrylic ester and on finely divided inorganic filler, which contain as adhesion promoters organosilicon compounds and metal acid esters, the casting resin composition containing zirconium acetylacetonate and water. The invention also relates to a process for the preparation of the casting resins and to their use.
