Abstract

A plastic molded body is produced that resembles natural materials such as marble, granite, etc. more closely that the prior products. The plastic molded body has a polymer phase produced from a hardenable reaction material, and a particulate filler material that is dispersed in the polymer phase. The filler material is a resin material that is filled with an inorganic filler. The polymer phase includes up to 60 wt % inorganic aggregate particles based on the weight of the plastic molded body. The filling material has a grain size of 60 to 8,000 μm and makes up approximately 5 to approximately 65 wt % of the plastic molded body. The filler material has at least 10 volume % of particles that have two or more differently colored, surface-visible polymer layers.
