Embodiment 1

[0108] In this embodiment, two layers of biaxially oriented polyolefin sheets are used to form the photographic element, and standard photographic paper photosensitive silver halide emulsions are coated on the polyolefin sheets. The photosensitive silver halide emulsion was coated on the polyethylene skin layer. The photographic originals are then printed with various images and developed using standard photographic paper wet chemical processing techniques. To produce a reflective print, a pressure adhesive is then used to laminate the developed image on the thin biaxially oriented sheet to the empty polymer matrix. This embodiment will show a significant improvement in image durability and image quality compared to standard photographic reflective paper. In addition, since the empty polymer matrix is ​​added after the image is formed, the cost of manufacturing and developing the image on the paper matrix is ​​avoided.

[0109] The biaxially oriented polyolefin sheet used in this ...

Embodiment 2

[0139] This imaging matrix was produced in the same manner as in Example 1, except that the empty polymer matrix was prepared with a density of 0.3 g / cc.

[0140] Empty polymer matrix used in Example 2

[0141] This example is formed in the same way as example 1, except that the production of the empty polymer matrix is ​​as follows:

[0142] The polypropylene loading is 35 wt%, and the stretching temperature is 100°C. The obtained stretched hollow polymer matrix has a density of 0.3 g / cc and a thickness of 450 microns.

Embodiment 3

[0143] Example 3 (control):

[0144] The control samples were prepared as described above, except that polyethylene resin photographic paper was used instead of the empty polymer matrix.

[0145]The photographic grade cellulose paper used in the present invention:

[0146] A blend of a standard Fourdrinier paper machine and mostly bleached hardwood kraft fiber was used to produce the paper substrate used in the present invention. The fiber ratio is mainly composed of the following materials: bleached poplar (38%) and maple / beech (37%) with a small amount of birch (18%) and softwood (7%). Using high-level cone fine crushing and low-level disk fine crushing, the weighted average fiber length is reduced from 0.73mm measured by Kajaaani FS-200 to 0.55mm. The fiber length of the slurry was measured using an FS-200 fiber length analyzer (Kajaani Automation Inc.). The energy applied to the fiber is indicated by Specific Net Refining Power (SNRP) and is 127 KW hr / metric ton. Two conical ...

Abstract

This patent relates to an imaging member comprising a vacuous polymer base having adhered thereto an image formed on a transparent polymer sheet, wherein said vacuous polymer base has a density of less than 0.7 grams / cc and a modulus to density ratio of between 1500 and 4000 and wherein said image is in contact with said vacuous polymer base.

Description

Technical field [0001] The present invention relates to photographic materials. In a preferred form, the invention relates to photographic reflection images. Background technique [0002] In the construction of color photographic papers, it is known that the base paper contains a polymer layer applied thereto, the polymer being typically polyethylene. This layer is used to provide water resistance to the paper and to provide a smooth surface on which the photosensitive layer is formed. The formation of a suitable smooth surface is difficult, requiring greater care and expense to ensure proper deposition and cooling of the polyethylene layer. Since when the reflective performance of the improved substrate is specularly reflective than the existing materials, the display material will have a greater apparent blackness, so the formation of a suitable smooth surface will also improve the image quality. When the white is whiter and the black is blacker, there ...
