  • Patent number: 5077185
    Abstract: An element comprising a support having an antistatic layer applied to one side thereof and wherein said antistatic layer also contains antihalation dyes absorbing light at 440 nm and below and with matte particles therein, is described. A photosensitive layer, e.g., photographic silver halide layer can be coated on the opposite side of the support. The element exhibits excellent antistatic and antihalation properties as well as low dye stain and improved dimensional stability, compared to elements wherein the antihalation dyes are coated in a separate layer. These products are especially useful as so-called "bright-light films" that are designed for contact printing and the like.
