PURPOSE:To obtain the title film suitable as flexible print plate, etc., having excellent mechanical properties, dimensional properties, etc., by blending a resin consisting essentially of a linear saturated polyethylene terephthalate with a specific amount of a specific cationic polymerizable compound, etc., to give a composition and photo-crosslinking the composition. CONSTITUTION:(A) A resin consisting essentially of a linear saturated polyethylene terephthalate is blended with (B) a cationic polymerizable compound consisting essentially of an epoxy resin containing two or more oxirane rings in one molecule, (C) a photopolymerization initiator for the component B, liberating Lewis acid catalyst by ultraviolet light irradiation and optionally (D) a polyester oligomer in the ratio of the component B/A of 5-50wt.% and in the ratio of the component C/B of 0.1-10wt.% when the component D is not added and in the ratio of the component B/A+D of 5-50wt.%, of the component C/B of 0.1-10wt.% and of the component D/A of 5-35wt.% and the blend is photo- crosslinked to give a film having >=10% insoluble content in immersion in o- chlorophenol at 100 deg.C for >=1 hour. |
