  • Patent number: 3949148
    Abstract: A transparency is disclosed, which is suitable for use in a multi-colored xerographic reproduction process comprising a transparent, thermoplastic film sheet having at least one surface coated with a mixture consisting of a vinyl chloride-acetate copolymer resin and an acrylic resin in a weight ratio of between about 6:4 and 7:3. In a preferred embodiment, a percentage of a particulate material is also incorporated in the coating to reduce static charge on the transparency and permit easier handling thereof. The coated transparency, when used in a multi-colored electrostatic copying process improves adhesion of the multi-colored image thereon and permits reproduction of colors and colors densities in said image which correspond well to the multi-colored original copied.
