A non-transparent microvoided biaxially stretched self-supporting non-laminated polymeric film, the film comprising linear polyester as a continuous phase and dispersed uniformly therein an amorphous high polymer with a higher glass transition temperature than the glass transition temperature of the continuous phase and/or a crystalline high polymer having a higher melting point than the glass transition temperature of said continuous phase, wherein said linear polyester consists essentially of aromatic dicarboxylate and aliphatic dimethylene monomer units; the polymeric film has an optical density measured in transmission with a visible filter; and at least 50% of the optical density is due to microvoids; the use of the non-transparent microvoided biaxially stretched film as a synthetic paper; an image recording element comprising the non-transparent microvoided biaxially stretched film; and a process for obtaining a transparent pattern therewith.
