Abstract
Cured, opaque coatings with high hiding power are produced on a substrate from a normally transparent and radiation transmitting unsaturated polyester paste filler composition containing customary additives, curing catalysts and optionally fillers of low hiding power and non-reactive solvents and/or plasticizers wherein the filler composition has a weight ratio of unsaturated polyester to the sum of copolymerizable monomers and optionally non-reactive solvents and plasticizers of from about 10 : 12 to 10 : 40, preferably from about 10 to 15. The unsaturated polyester filler composition may further have up to 95 percent by weight of the copolymerizable monomers replaced by the non-reactive solvents and/or plasticizers. The composition may be cured by UV rays, sunlight or other ionizing radiation.
