This invention relates to an imaging element comprising an imaging layer having associated therewith a blocked polymeric compound in which the blocking group, between the developing agent and the polymeric backbone, is heteroaromatic. Such compounds have good reactivity and can by used to block photographically useful compounds such as developing agents until thermally activated under preselected conditions. Compounds according to the present invention are especially useful in color photothermographic imaging elements.
