To prevent occurrence of a blocking phenomenon in the case when a print film is made a roll-like formed material, by forming a print layer inside a supporting base.
A print film is made to have a structure wherein a print layer exists inside a supporting base and is sandwiched by the supporting base. For the print layer, a print layer constituted of synthetic resin and a pigment at least is used and, as for the synthetic resin to be used, the one being suitable to the supporting bases is selected. In the case when the material of the supporting base is polyolefin, for instance, urethane or acrylic resin is used. When it is polyvinyl chloride, acrylic or polyvinyl chloride resin or the like is used. As for the pigment, an inorganic pigment such as a titanium oxide and an organic pigment such as phthalocyanine are used. By using this print film as a substrate and by providing an adhesive layer on one side of the film, accordingly, the print layer is prevented from being brought into blocking by the adhesive layer in rewinding, without impairing weather resistance, in the case when the film is made a roll-like formed material.
