Abstract

A clay pigeon used as a target in trapshooting or skeet shooting which is made by molding a composition comprising low molecular weight thermoplastic resin, high molecular weight thermoplastic resin and inorganic powdered filler, and if desired, additives, pigments and/or antioxidants are added to the composition. The clay pigeon is itself light colored without the need for a light coloring finish and contains no noxious material.

Claims

1. A clay pigeon for use as a target in trapshooting or skeetshooting molded from a composition comprised of:

60 to 100 parts by weight of at lest one member of low molecular weight thermoplastic resin having an average molecular weight of 300-3000 and a softening point, determined by the ring and ball method, of 60°

-200°

C, selected from the group consisting of petroleum resin, rosin, rosin esters, polyterpene resin, xylene resin, coumaron-indene resin, low molecular weight polystyrene and their hydrogenated derivatives;

0-40 parts by weight of at least one member of high molecular weight thermoplastic resin having an average molecular weight of 5000-1,000,000, selected from the group consisting of polyethylene, polypropylene, poly-butene-1, 1-2 polybutadiene, polystyrene, poly-oc-methyl styrene, polyvinyl chloride, polymethyl methacrylate, polyamide resin, polyester resin, thermoplastic polyurethane, ethylene-propylene block copolymer, ethylenevinylacetate copolymer, ethylene-ethylacrylate copolymer, styrene-butadiene block copolymer and styrene-isoprene block copolymer; and

100-900 parts by weight of inorganic powdered filler per 100 parts of the total amount of the low molecular weight and high molecular weight thermoplastic resins.

2. The clay pigeon described in claim 1, wherein said inorganic powdered filler is at least one member selected from the group consisting of calcium carbonate, talc, clay, alumina white, mica powder, aluminum sulfate, barium sulfate, gypsum, calcium sulfite, lithopone, pumice powder, glass powder, zinc white, magnesium carbonate, metal powder, asbestos powder and titanium oxide.

3. A clay pigeon for use as a target in trapshooting or skeet-shotting molded from a composition comprised of:

70 to 98 parts by weight of low molecular weight thermoplastic resin having an average molecular weight of 500-2000 and a softening point, determined by the ring and ball method, of 80°

-190°

C;

- 30parts by weight of high molecular weight thermoplastic resin having an average molecular weight of 10,000-500,000; and

200-800 parts by weight of inorganic powdered filler per 100 parts of the total amount of the low molecular weight and high molecular weight thermosplastic resins.
