Embodiment 1-10

[0074] Examples 1-10 include tricolor emulsions prepared as described above. The photosensitive emulsion is coated on any of the standard photographic white reflective substrates such as Table 2. Some substrates that can be used are white pigmented polyethylene resins coated on paper or polyester substrates, white pigments incorporated into polyester, white pigmented and / or voided bilayer laminated to substrates. Axis-oriented polymers. The substrates used in these examples and comparative examples were the same. It says it has 26g / m 2 About 160g / m of pigmented polyethylene 2 Typical photographic paper substrate for photographic grade paper. This layer contains about 12% by weight anatase TiO 2 , fluorescent whitening agent and blue coloring matter. The back is a layer of 28g / m 2 of transparent polyethylene. In Comparative Example and Sample 7, there was no pearlescent pigment in any layer, whereas in Examples 1-6 and 8-10, the pearlescent pigment was provided in at le...

Embodiment 11

[0076] Example 11 is the same as the other examples except that it includes an extra layer at the bottommost position in the emulsion coating. This layer contains about 45g / m 2 of photographic grade gelatin and 0.5% by volume of the same pearlescent pigment as above.

[0077] Example

[0078] After image exposure and development, the samples were observed by visual inspection under typical room light conditions for cool white fluorescence.

[0079] The results of the visual inspection are tabulated in Table 5. While viewing the sample, the print was rotated through an angle of incidence from 0 to 70 degrees relative to the observer. Observers look for a full glossy appearance.

[0080] Example

[0081] As shown by the data in Table 5, a pearlescent appearance can be observed as long as the pearlescent pigment is present in the emulsion layer, even in the sublayers of the emulsion. This observation is a visual assessment of the sample using reflected lig...

Abstract

The invention relates to a photographic element comprising nacreous pigment.

Description

technical field [0001] This invention relates to imaging materials. In a preferred form it involves pearlescent photographic reflective paper. Background technique [0002] Prior art reflective imaging output materials such as silver halide reflective images or inkjet reflective images typically comprise an imaging layer applied to a white reflective substrate. The white reflective substrate reflects ambient light back into the observer's eyes to form an image in the brain. Prior art substrates typically employ white reflective pigments such as TiO in a polymer matrix 2 or barium sulfate to form a white reflective substrate. Prior art reflective photographic papers also contain white pigments in the carrier just below the silver halide imaging layer to achieve image whiteness and sharpness when the image is exposed, because the white pigments reduce the amount of exposure energy scattered by the cellulose paper core . Details regarding the use of white pigments in highl...
