 Photographic element containing a light absorbing matting agent

Details
Inventors: Heigold, Frederick R.; Hoskyns, Wesley F.;
Assignee: Eastman Kodak Company (Rochester, NY)
Primary Examiner: Brammer; Jack P.
Assistant Examiner:
Attorney, Agent or Firm: Levitt; Joshua G.

Photographic elements containing a light absorbing matting agent overcome the "starry night" effect.

DETAILED DESCRIPTION What is claimed is: 1.
In a photographic element comprising a support bearing at least one layer of a radiation sensitive silver halide emulsion and, overlying and adjacent said emulsion layer, a matte layer of a transparent polymeric vehicle containing a matting agent, the improvement wherein the matting agent comprises pigmented polymeric particles which are of the same color as the image to be formed in the adjacent emulsion layer.
2.
A photographic element of claim 1 wherein the weight ratio of transparent polymeric vehicle to matting agent is between 4:1 to 50:1.
3.
In a photographic element comprising a support bearing at least one layer of a radiation sensitive silver halide emulsion and, overlying and adjacent said emulsion layer, a matte layer of a transparent polymeric vehicle containing a matting agent, the improvement wherein the matting agent comprises black polymeric particles.
4.
A photographic element of claim 3 wherein the layer containing the matting agent is the outermost layer of the photographic element.
5.
A photographic element of claim 4 wherein the transparent polymeric vehicle is gelatin, a gelatin derivative or combinations thereof.
6.
A photographic element of claim 4 wherein the black polymeric particles are spherical polymeric beads having carbon black dispersed therein.
7.
A photographic element of claim 5 wherein the black polymeric particles are spherical beads of a polymeric ester of acrylic or methacrylic acid or a polyvinyl resin, the beads having carbon black dispersed therein.
8.
A photographic element of claim 6 wherein the polymeric beads are comprised of poly(methyl methacrylate).
9.
A photographic element of claim 6 wherein the polymeric beads have a mean diameter of 2.
5 to 10 microns.
10.
A photographic element of claim 8 wherein the polymeric beads have a mean diameter of 4 to 6 microns.
11.
A photographic element of claim 6 wherein the polymeric beads comprise 2 to 15 percent by weight carbon black.
12.
A photographic element of claim 8 wherein the polymeric beads comprise 4 to 8 percent by weight carbon black
