FILM FOR OVERHEAD PROJECTOR FOR PRESSURE FIXING COPYING MACHINE

PURPOSE:To obtain a fine film for an overhead projector with no offsetting property by forming a transparent layer of resin having rubberlike elasticity at ordinary temp. on a transparent film so as to force a toner image into the resin layer by pressure fixing. CONSTITUTION:Natural rubber, butadiene rubber, urethane rubber or other transparent resin having rubberlike elasticity at ordinary temp. is applied or adhered to a transparent film of polyethylene terephthalate or the like to form a transparent layer. To the layer may be added about 1% antiblocking agent such as SiO2 and ester resin or the like for enhancing the adhesion to the substrate film. Thus, a toner is well fixed on the transparent layer by anchoring effect with a pressure fixing type copying machine. Accordingly, an offsetting phenomenon by which a toner is shifted to a fixing roller during fixing is prevented to give a fine image.
