Abstract:
1. A printable paper comprising a water-resistant support having two optionally subbed sides and a single layer on at least one of said optionally subbed sides, wherein said single layer has no substantial compositional variation, has a layer thickness of at least 3 μm, a pore volume of at least 1.2 mL/m 2 and comprises at least one porous pigment, wherein said water-resistant support is a non-transparent microvoided axially stretched directly extruded linear polyester having dispersed therein from 5 to 20% by weight of at least one amorphous high polymer having a higher glass transition temperature than that of said linear polyester and from 0.1 to 10% by weight of at least one crystalline high polymer having a higher melting point than the glass transition temperature of said linear polyester, wherein said crystalline high polymer is isotactic poly(4-methyl-1-pentene), wherein said amorphous high polymer is selected from the group consisting of polystyrene, styrene copolymers, styrene-acrylonitrile-polymers, polyacrylates, acrylate-copolymers, polymethacrylates and methacrylate-copolymers.
