The present invention provides an insulated wire having a heat-resistant insulating layer, wherein heat-resistant particles are contained in the insulating layer, and the heat-resistant particles are densely dispersed in a surface region of the insulating layer. For example, the concentration of heat-resistant particles included in a layer thick portion of 0.5 m from the surface of the insulating layer is two times the concentration of heat-resistant particles included in a central portion of the insulating layer. An electrodeposition liquid used to form the insulating layer is formed by dispersing the heat-resistant particles in a suspension in which resin particles are dispersed, the viscosity is 100 cP or less, and the turbidity is 1 mg/L or more.

Disclosed is a process for on- and off-site tagging of fracking sand and a composition of matter capable of being utilized in that process. The composition of matter includes a linker polymer conjugated to a rare earth particle. The method involves forming two mixtures, a first involving mixing a linker polymer conjugated to a rare earth particle into an aqueous blend of fracking sand, and a second involving an activated amine terminated polymer in an aqueous solution. The second mixture is then added to the first mixture, and covalent amide bonds are formed.
