PURPOSE:To enable the improvements of separating workability and a property of the finished appearance of a photocopied image substance by the use of photocopying resin composed of resin consisting mainly of a saponified substance of polyvinyl acetate and a specific separating liquid for close-up photocopying. CONSTITUTION:A separating sheet can be used which has a photocopied image layer 3 formed on the surface of a resin layer 1 by photocopying a photocopying sheet having a photocopying resin layer 1 and a mold releasing layer 2 by means of a photocopying machine. Subsequently, the photocopying resin layer is of the type that is formed with resin consisting mainly of a saponified substance of polyvinyl acetate and can contain an additive, pigment or the like as required. Furthermore, a mold releasing layer of dimethyl siloxane or the like can also be provided between the resin layer 1 and the mold releasing layer 2 as required. Herein, although a monochromatic or color photocopying machine can be used as a photocopying machine, electronic photocopying one is preferable in which toner particles are fixed by an electrostatic method. During photocopying, the photocopied image layer 3 Is caused to be transferred and converted in the next process, so that the original patterns are photocopied on the rear surface.
