ル性を改良するために設けられるのである。(Prior Art) Diazo copying materials are known in which a precoat layer and a diazo photosensitive layer are provided on the surface of a support such as paper or plastic film, and a backcoat layer is provided on the back surface.
This precoat layer is made of a pigment such as particulate silica and a binder, and is provided to increase the image density, sharpen the color tone of the image, and provide writability. Further, the back coat layer consists only of a binder and is provided to improve the curling properties of the diazo copying material.

との自動分離が非常に困難であつた。 Such diazo copying materials have a large coefficient of friction, so if they are passed through a copying machine with an automatic paper feed or automatic separation mechanism, the friction between the surfaces of the diazo copying materials may cause the paper to not be fed or may not be able to be fed. Also, the sheets were sometimes fed overlapping each other at once, and it was very difficult to automatically separate the diazo copying material from the original.
