Opaque coatings or films having a high covering capacity produced from coating compositions containing synthetic resins, fillers, solvents, common catalysts, sensitizers, additives and auxiliary agents, characterized in that radiation permeable mixtures of coating compositions are used containing the following components:

Compositions for the production of opaque coatings by radiation

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.

Cured opaque coating with high hiding power produced from normally

Opaque coatings and films produced by the hardening of synthetic resins

Opaque coatings and molded articles are produced from normally transparent copolymer compositions of unsaturated polyesters and monomers therefore by using from about 3 percent to less than 45 percent by weight of unsaturated polyesters based on the total weight of the composition.
