Embodiment 1

[0090] The following prior art reflective display materials were used as comparative materials in the present invention:

[0091] Kodak Duraflex (Eastman Kodak Company) is a colored silver halide coated on one side containing BaSO 4 and optical brightener polyester support (256 μm thick).

[0092] The laminated photographic display materials described below (invention) were prepared by extrusion laminating the sheets described below to the top side of a photographic grade polyester base.

[0093] Top side sheet (emulsion side):

[0094]Composite sheet consisting of 5 layers labeled L1, L2, L3, L4 and L5 respectively. L1 is the thin colored layer on the outside of the module with a light sensitized silver halide layer attached to it. L2 is added optical brightener and TiO 2 layer. The optical brightener used was Hostalux KS from Ciba-Geigy. The rutile TiO used 2 It is DuPont R104 (TiO 2 The particle size is 0.22 μm). Table 1 below lists the characteristics of the layer...

Abstract

The present invention relates to photographic elements comprising a transparent polymeric support, at least one biaxially oriented polyolefin sheet, and at least one imaging layer, wherein said polymeric support has a stiffness between 20 and 100 millinewtons, said biaxially oriented polyolefin sheet and at least one imaging layer. The spectral transmission of the axially oriented polyolefin flakes is less than 15%.

Description

technical field [0001] This invention relates to photographic elements. In a preferred form it relates to base materials for photographic reflective displays. Background technique [0002] Photographic display materials are known in the art for advertising and scenic displays of photographic images. Since these display materials are used in advertisements, the image quality of the display materials is decisive in expressing the quality information of the advertised product or service. Further, photographic display images are required to be highly impactful in order to attract consumer interest in the display material and the intended message. Typical applications for display materials include product and service advertisements, movie posters and fine art photographs in public places such as airports, bus stations and stadiums. Desired characteristics of a high-quality, high-impact photographic display material are minimal bluish density, durability, clarity, and flatness....
