摘要:
The present invention describes an apparatus for removing scratches from a photographic element. The apparatus includes an application device for applying a wax composition to a surface of a moving photographic web; and a buffing device for buffing the surface of the web having the applied wax composition. The present invention is also a method for removing scratches from a photographic element. The method includes the steps of providing a moving photographic web, applying the wax composition to a surface of the photographic web, and rubbing the wax composition with sufficient force thereby removing the residual wax composition to produce a refinished surface substantially free of all defects and scratches.

The present invention is a photographic element which includes a support, at least one silver halide emulsion layer, and a light-insensitive protective overcoat. The light insensitive protective overcoat includes a hydrophilic binder and polymer particles having a glass transition temperature of at least 70.degree. C. The polymer particles prepared by the process of mechanically forming oil-in-water droplets having a size less than 400 nm of an ethylenically unsaturated monomer having hydrophobic groups, the hydrophobic groups having a logP.sub.(calc) greater than a logP.sub.(calc) of the ethylenically unsaturated monomer by at least 1 unit in an aqueous medium. A hydrophilic colloid is added to the aqueous medium in an amount sufficient to render the polymer partice compatible with the hydrophilic binder. The droplets are polymerized to a size of less than 400 nm. The present invention is also a photographic element which includes a support, at least one silver halide emulsion layer, and a light-insensitive protective overcoat. The light insensitive protective overcoat includes a hydrophilic binder and polymer particles having a glass transition temperature of at least 70.degree. C.
