<p>A film consisting essentially of a continuous phase linear polyester matrix having dispersed therein a non-crosslinked random SAN-polymer and dispersed or dissolved therein at least one ingredient from the group of ingredients consisting of inorganic opacifying pigments, whitening agents, colorants, UV-absorbers, light stabilizers, antioxidants and flame retardants, wherein the film is white, microvoided, non-transparent and axially stretched; the linear polyester matrix has monomer units consisting essentially of at least one aromatic dicarboxylic acid, at least one aliphatic diol and optionally at least one aliphatic dicarboxylic acid; and the weight ratio of the linear polyester to the non-crosslinked SAN-polymer is in the range of 2.0:1 to 19.0:1, wherein one of the said at least one aliphatic dimethylene monomer units is selected from the group consisting of neopentylene and 1, 4-cyclohexanedimethylene in a concentration of 30 mole % or less of all aliphatic dimethylene monomer units; the use of the film as or in synthetic paper; an image recording element comprising the film; a process for the preparing of the non-transparent microvoided axially stretched film; and a process for obtaining a transparent pattern therewith.</p> |
