【発明の詳細な説明】 （発明の分野） 本発明は写真用印画紙に関し、さらに詳しくは裏面に褪
色性あるいは安全性の優れた染料が用いられている写真
用印画紙に関するものである。Description: FIELD OF THE INVENTION The present invention relates to a photographic printing paper, and more particularly to a photographic printing paper having a back surface containing a dye having excellent fading or safety.
（従来技術） 写真用印画紙は基本的に、支持体、ハロゲン化銀乳剤層
（写真乳剤層）、および保護ゼラチン層から構成される
が、支持体として原紙を使用する場合、原紙に耐水性を
付与するために、一般に原紙の両面をポリエチレン等の
ポリオレフイン樹脂で被覆することが行なわれている。(Prior Art) A photographic printing paper is basically composed of a support, a silver halide emulsion layer (photographic emulsion layer), and a protective gelatin layer. When the base paper is used as a support, the base paper is water resistant. In order to impart the property, both sides of the base paper are generally coated with a polyolefin resin such as polyethylene.

画紙において写真用乳剤層が塗設されている側の面は
「表面」、そして写真用乳剤層が塗設されていない側の
面は「裏面」と呼ばれる。In the photographic printing paper using such a polyolefin resin-coated paper, the side on which the photographic emulsion layer is coated is the "front side", and the side on which the photographic emulsion layer is not coated is the "back side". Is called.

紙固形分に対し約０．０１乃至１０ppmの範囲が良い。The amount of Acid Black2 used depends on the type of pulp used for papermaking,
Beating degree, strength agent, type and amount of sizing agent,
Although it depends on the type of solvent that dissolves Acid Black 2, it is preferably in the range of about 0.01 to 10 ppm relative to the solid content of the base paper.
本発明によれば黒色染料としてAcid Black2を使用する
ことにより (1)印刷物が太陽光、紫外線、キセノン光による褪色が
少ない優れた写真用印画紙を作ることができる。According to the present invention, by using Acid Black 2 as the black dye, (1) an excellent photographic printing paper can be produced in which the printed matter has little fading due to sunlight, ultraviolet rays, and xenon light.
(2)毒性の点で問題のない安全な製品を作ることができ
る。(2) It is possible to make a safe product with no problem in terms of toxicity.
(3)溶媒に対する溶解性が良いために、染料溶解時の作
業性が良い。(3) Workability when dissolving the dye is good because the solubility in the solvent is good.
(4)銀塩乳剤に対する写真性の優れた写真用印画紙を作
ることができる。(4) It is possible to produce photographic printing paper with excellent photographic properties against silver salt emulsion.
などの効果があげられる。And the like.
