Composite materials that include a resin containing a polymer obtained by polymerizing a monomer mixture that contains at least one polymerizable monomer and a magnetic material, where the composite material can be used to make sheet stock and articles, such as storage containers. The composite materials can be made by mechanical milling the magnetic material into the resin or by using bulk, suspension, emulsion, mini-emulsion or micro-emulsio n polymerization techniques where the resin is formed in the presence of the magnetic material. Articles made of the composite material can be used in a method of deterring theft of an article which includes providing the above- described container, applying a magnetic field to an interrogation zone, causing movement of the container into the interrogation zone, and detecting a magnetic response resulting from the container moving into the interrogation zone. |
