ABSTRACT A tagging means containing ferromagnetic con-stituents, optionally fluorescent pigments, microanalytically detectable quantities of soluble and insoluble fluorescent materials, colored pigments, oxides and/or salts of rare metals as well as oxides and/or poorly soluble salts of rare earths embedded in an uncured thermoplastic resin poly-acrylates, polyester or polymer epoxide powder varnish base, are produced by homogeneously incorporating the components into the melting thermoplastic resin, cooling and pulverizing the mixture to a fine particle size. |
