    Abstract: The present invention relates to a double-sided photosensitive color photographic paper and a method for manufacturing the same. The photographic paper comprises a paper base, and a first photosensitive layer and a second photosensitive layer provided on two opposite sides of the paper base, respectively, wherein a silver shading layer is coated between the paper base and the first photosensitive layer and/or between the paper base and the second photosensitive layer. The function of the silver shading layer is to block majority of light so that light exposed to one side of the photographic paper will not expose to the photosensitive layer on the other side of the photographic paper. Therefore, undesired images on the other photosensitive layer and degradation of the original imaging quality can be avoided. Sliver in the silver shading layer can be removed during the development of the photographic paper, and the final viewing quality of the photographic paper will not be impacted.
