Abstract

A double sided photographic color paper comprises a support, a photosensitive coating, and a covering layer. After improvement, a shading layer and a barrier layer are arranged between the support and the photosensitive layer. The barrier layer is arranged between the shading layer and the photosensitive layer. The other side of the support is supported with a second photosensitive layer, a second barrier layer, a second photosensitive and a second covering layer which are symmetrically arranged with the photosensitive layer, the barrier layer, the photosensitive and the covering layer. The color paper has rich color, wide color field, rich image level, high definition, high efficient, low cost and is convenient for seeing and enjoying.

Description

technical field [0001] The invention relates to a photographic material, in particular to a double-sided photosensitive color paper. Background technique [0002] Traditional single-sided photosensitive color paper can only be exposed on one side of the paper to form a single-sided image, and the reverse side has no image. This can only be installed in a photo frame or photo album for one-sided appreciation, and cannot expand the scope of use of photo paper as an image carrier. Moreover, the utilization rate of the support body is reduced, and the manufacturing cost is increased. In recent years, digital short-run double-sided printing has sprung up, and the annual market capacity has expanded rapidly. Digital short-run double-sided printing, mainly based on digital printing and inkjet printing, can bring consumers double graphics and text on a limited plane carrier. Information is widely used in business cards, personalized desk calendars, menus, auction house sample book...
