PURPOSE:To enhance the adhesive property of a polyester film and a vapor deposited metallic layer by forming a specific reforming layer on the polyester film and stretching the film, then providing the vapor deposited metallic layer thereon. CONSTITUTION:This photosensitive material is formed by laminating a photoconductor layer on a conductive base consisting of the polyester film and the vapor deposited metallic layer. The reforming layer essentially consisting of aq. self-emulsification type thermo-reactive urethane (A) having <=50% rate of solvent swelling is applied on the above-mentioned film and while the film is dried, the film is stretched in at least one direction; thereafter, the metallic layer is deposited by evaporation thereon, by which the base is formed. The component A or the like obtd. by bringing polyester having >=2 piece of hydroxyl groups and excess amt. of polyisocyanate to produce an urethane propolymer and blocking the isocyanate group is usable. |
