Abstract
Disclosed are photographic elements having reflective or diffusely transmissive supports shaped from a continuous oriented polymer phase having dispersed therein microbeads of a polymer which are at least partially bordered by void space, the microbeads being present in an amount of about 5-50% by weight based on the weight of the oriented polymer, and the void space occupying about 2-60% by volume of the support. Preferably, the microbeads are cross-linked to an extent they will be resilient and elastic at the orientation temperature, and are coated with a slip agent. Such supports have excellent physical properties.
