れている。(Prior art) Conventionally, so-called baryta paper, in which one side of the paper is coated with a baryta layer mainly composed of barium sulfate, has been used as a support for photographic paper, but recently, in order to automate and speed up the development process, Waterproof photographic paper, in which both sides of the base paper are coated with resin, has come into use. However, even when the waterproof photographic paper is used, it is not possible to prevent the developer from permeating through the cut edges of the photographic paper. The developer that permeates through the cut edges cannot be removed by short-term photo processing, and will turn brown due to heat or over time, staining the etched areas of the photo.
The value as a photograph is significantly diminished. In order to prevent this etching stain, attempts have been made to provide the base paper layer with a high degree of size.

。Fatty acid soap type sizing agents as shown in JP-B No. 47-26961 @ and alkyl ketene dimers as shown in JP-A-51-132822 have been used as sizing agents for photographic paper supports, but each has drawbacks. have, but are not sufficient. That is, fatty acid soap type sizing agents have drawbacks such as having a low sizing effect on alkali in the developer and being easily affected by the hardness of water when producing base paper. On the other hand, alkyl ketene dimers have a low size effect on the alcohol in the developer,
Furthermore, it has the disadvantage that sufficient sizing properties cannot be obtained unless a relatively large amount of polyamide polyamine epichlorohydrin resin, which is known as a fixing agent, is used, and neither sizing agent is fully satisfactory for use in photographic paper. .
