ABSTRACT:
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.
