Abstract
In a photographic element amenable to heat development or mobile dye heat transfer, an electroconductive layer is formed from a composition containing an electroconductive substance, typically carbon black and a high molecular weight compound having a glass transition temperature of not higher than 40.degree. C. at a relative humidity of 20% or a melting point of not higher than 180.degree. C., for example, polyethylene glycol, such that the conductive layer undergoes a minimized change in electric resistance when folded.
