<p>Thermographic elements comprising at least two layers, wherein: at least one of the layers comprises polymer, the polymer consisting essentially of, repeating, interpolymerized units derived from 9,9-bis-(4-hydroxyphenyl)-fluorene and isophthalic acid, terephthalic acid or blends thereof, the polymer being sufficiently low in oligomer content to allow formation of uniform film; and at least one of the layers is an imaging layer, selected from the group consisting of dye-donor layers, image-receiving layers or heat-activatable imaging layers, and a method of thermal imaging using receptor films comprising the polymer described above.</p> |
