Problems solved by technology

However, the introduction of the above-mentioned coating causes the following problems in the double-sided photo paper: 1. The whiteness of the double-sided photo paper tends to deteriorate, reducing the image quality of the photo paper; 2. The light-blocking effect of the light-blocking layer has certain limitations. Especially under strong exposure conditions such as laser exposure, light is easy to penetrate to form negative interference images; 3. It increases the production difficulty and manufacturing cost of double-sided photo paper, and at the same time complicates the processing technology

Embodiment 1

[0089] Using the transfer vacuum evaporation coating method, at 1.3×10 -2 ~1.3×10 -3 Heating high-purity aluminum in a vacuum environment of Pa makes the aluminum evaporate in a short time, and the aluminum wire evaporates into atoms under the action of high temperature of 1400 ° C, deposits on the resin film, and condenses into a fine and dense bright aluminum film after being cooled by a water-cooled roller. Adjust the time of vacuum deposition to control the thickness of the film, and then transfer the aluminum film to one side of the photographic base paper through adhesive transfer, compound the same aluminum film on the other side of the photographic base paper in the same way, and finally peel off the resin film.

[0090] Process the mixture of granular resin, white masterbatch and color masterbatch in a certain proportion into a molten body by extrusion and heating and pressure on the composited aluminum film, and then form a molten film through the action of the die h...

Embodiment 2

[0093] Using the magnetron sputtering coating method, at 1.3×10 -1 Nitrogen is filled in a vacuum of about Pa, and a high-voltage direct current is applied between the plastic substrate (anode, such as polyester film) and the metal target (cathode, such as metal tin), and the electrons generated by the discharge excite the inert gas to generate plasma. body, the plasma knocks out the atoms of the metal target sn and deposits it on the resin film to form a tin metal film, the thickness of the film is controlled by adjusting the deposition time, and the tin metal film is transferred to the base paper through a suitable adhesive On one side; peel off the resin film and transfer the tin metal film to the other side of the photographic base paper in the same way.

[0094] Process the mixture of granular resin, white masterbatch and color masterbatch in a certain proportion into a molten body through extrusion and heating and pressure on the composited tin film, and then make it int...

Abstract

The invention discloses a photographic paper base for double-sided imaging and double-sided sensitive color photographic paper containing the same. The photographic paper base comprises a piece of photographic base paper, a polymer layer and a contact layer, wherein a light blocking layer is arranged between the photographic base paper and the polymer layer; and a second light blocking layer, a second polymer layer and a second contact layer symmetrical with the light blocking layer, the polymer layer and the contact layer are arranged on the other surface of the photographic base paper. The photographic paper base has good light blocking effect, and can effectively eliminate negative interference images caused by light transmission during double-sided imaging without introducing an independent light blocking layer and an independent blocking layer. The double-sided sensitive silver halide color photographic paper adopting the photographic paper base provided by the invention can be fully adaptive to the exposure in a range of 10 to 7-102 seconds; and the obtained double-sided images have rich colors, wide color gamut, rich image levels and high definition.

Description

technical field [0001] The invention relates to a photographic material, in particular to a photographic paper base for double-sided imaging and a double-sided photosensitive color photographic paper containing the paper base. Background technique [0002] Traditional single-sided photosensitive color photo paper can only be exposed on one side of the photo paper to form a single-sided image, and there is no image on the reverse side, so it can only be viewed on one side in a photo frame or album, which virtually limits the use of photo paper as an image carrier. The range reduces the utilization rate of the support body and increases the manufacturing cost. In recent years, digital short-run double-sided printing based on digital printing and inkjet printing has sprung up, and the market capacity has expanded rapidly. Double-sided printing of digital short boards can bring consumers double the graphic information on a limited plane carrier, which improves efficiency to a c...
