Claims
- 1. An imaging element comprising:
- a support having a front side and a back side;
- at least one backing layer on the back side of said support;
- at least one silver halide emulsion layer superposed on the front side of the support;
- an interlayer superposed on said at least one silver halide emulsion layer having a thickness of between 0.2 .mu.m and 1.2 .mu.m and a stiffness ratio of said interlayer to said at least one silver halide emulsion layer of from 2 to 15; and
- a protective overcoat layer superposed on said interlayer having a thickness of from 0.3 to 2 .mu.m wherein a ratio of the thickness of said interlayer to said protective overcoat layer is less than or equal to 1.
- 2. The imaging element of claim 1 wherein said support is selected from the group consisting of polymeric films, papers, and glass.
- 3. The imaging element of claim 1 wherein said support has a thickness of from 2 to 10 mil.
- 4. The imaging element of claim 1 further comprising a subbing layer interposed between said support and said at least one silver halide emulsion layer.
- 5. The imaging element of claim 1 wherein said protective overcoat layer comprises a hydrophilic colloid, a wetting aid, and organic or inorganic matte beads.
- 6. The imaging element of claim 5 wherein said protective overcoat further comprises lubricants, hardeners, image stabilizers, filter dyes, or dispersing aids.
- 7. The imaging element of claim 1 wherein said protective overcoat has a thickness of from 0.3 to 1.2 .mu.m.
- 8. The imaging element of claim 1 wherein said interlayer comprises a hydrophilic colloid and a compatible polymer or hard fillers.
- 9. The imaging element of claim 8 wherein the hard fillers comprise inorganic oxide particles or polymer particles having a Tg of 30.degree. C. or greater.
- 10. The imaging element of claim 8 wherein the hard fillers have a particle size of from 2 nm to 500 nm.
- 11. The imaging element of claim 1 wherein said interlayer further comprises surfactants, dispersing aids, hardeners, or filter dyes.
