[0004] Whether it is a three-component or a single-component single-sided photo paper developer, it is not suitable for processing double-sided color photo paper. As the characteristics of the above-mentioned double-sided photo paper, there is a light-blocking layer and a barrier layer between the support and the photosensitive layer. , the second light-blocking layer and the second barrier layer are symmetrically arranged on the other side of the support. The traditional single-sided color photo paper developer cannot effectively remove the light-blocking layer, nor can it compensate for the damage caused by the light-blocking layer. Insufficient exposure due to light-absorbing substances

Abstract
The invention discloses a color photographic paper developing concentrated solution and particularly relates to a double-sided color photographic paper developing concentrated solution. According to the characteristics of double-sided photosensitive color photographic paper, the color photographic paper developing concentrated solution has good surface seepage capacity, can be used for quickly dissolving and removing light-blocking layer substances of the photographic paper, and also can be used for ensuring satisfactory photographic sensitivity and visual whiteness.
Description
technical field [0001] The invention relates to the technical field of photography, in particular to a color photographic paper developing concentrate. 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, which cannot expand the scope of application of photo paper as an image carrier, and reduces the utilization rate of the support body and increases the manufacturing cost. The Chinese patent application number 200820106796.9 discloses a double-sided photosensitive color photo paper, which includes a support, a photosensitive layer and a protective layer, wherein a light-blocking layer and a barrier layer are arranged between the support and the photosensitive layer, and the support The other side is provided with a second light-blocking layer, a secon...
