Pencil writable and printable synthetic paper comprising a finely porous polyolefin film layer having an opacity of at least 80% obtained by stretching a polyolefin film containing from 8 to 65% by weight of an inorganic fine powder having on one or both sides thereof a stretched ethylene-vinyl alcohol copolymer film layer, at least one of the stretched ethylene-vinyl alcohol copolymer film layers having a coat layer thereon. When printed, the stretched ethylene-vinyl alcohol copolymer film layer prevents hydrocarbon solvents present in printing inks from penetrating into the polyolefin film layer to eliminate local surface unevenness and curling.

Synthetic paper for writing and printing

A synthetic paper printable in high gloss comprises (1) a multilayer support, (2) a layer of a transparent film of a thermoplastic resin free from an inorganic fine powder formed on one surface of the support (1), and (3) a primer layer of a specific material. The support (1) comprises (1a) a base layer of a biaxially stretched film of a thermoplastic resin and a surface and a back layer (1b) and (1c) composed of a monoaxially stretched film of a thermoplastic resin containing from 8 to 65% by weight of an inorganic fine powder.
