ABSTRACT:
This invention provides a transparent, paramagnetic polymer composition in which a polymer is completed with sufficient rare earth ions, particularly ions selected from ions in the group of elements 64-69, to provide a polymer with a magnetic mass susceptibility greater than 20×10−6emu/g measured at 298° K.This invention provides optically responsive devices that employ these transparent, paramagnetic polymers as an element that is responsive to a magnetic field and a means for providing magnetic field.This invention provides transparent labels or markings employing these transparent, paramagnetic polymers.
