Claims
- 1. A photographic element comprising a paper substrate with a polyolefin coating provided on at least one surface, a hydrophilic colloid layer on the polyolefin coating, and at least one light sensitive silver halide emulsion above the hydrophilic colloid layer, wherein said hydrophilic colloid layer comprises a removable antihalation material and about 20 to 85 percent by weight white pigment.
- 2. The photographic element of claim 1 wherein the hydrophilic colloid layer contains an optical brightener.
- 3. The photographic element of claim 1 wherein the white pigment is TiO.sub.2.
- 4. The photographic element of claim 1 wherein the white pigment is anatase TiO.sub.2.
- 5. The photographic element of claim 1 wherein the white pigment is rutile TiO.sub.2.
- 6. The photographic element of claim 1 wherein the hydrophilic colloid is present in the amount of from about 5 to about 50 percent by weight.
- 7. The photographic element of claim 1 wherein the hydrophilic colloid is present in the amount of from about 8 to about 35 percent by weight.
- 8. The photographic element of claim 1 wherein the hydrophilic colloids is present in the amount of from about 10 to about 25 percent by weight.
- 9. The photographic element of claim 1 wherein the hydrophilic colloid is gelatin.
- 10. The photographic element of claim 2 wherein the optical brightener is loaded on a latex polymer.
- 11. The photographic element of claim 1 wherein the hydrophilic colloid layer is coated at a coverage of at least about 5.4 g/m.sup.2.
- 12. The photographic element of claim 1 wherein the hydrophilic colloid layer is coated at a coverage from about 5.4 g/m.sup.2 to about 16.2 g/m.sup.2.
- 13. The photographic element of claim 1 wherein the hydrophilic colloid layer is coated at a coverage from about 7.5 g/m.sup.2 to about 10.9 g/m.sup.2.
- 14. The photographic element of claim 1 wherein said antihalation material comprises colloidal silver.
- 15. The photographic element of claim 1 wherein said antihalation material comprises a filter dye.
