用支持体の製造方法である。(Means for Solving the Problem) The present invention provides a method for running a photographic support in which a polyolefin resin coating layer is provided on both sides of a base paper in a line, so that the coefficient of static friction when the resin-coated photographic support holds a paper roll is 0.2 to 0.6, including those in which the surface coating layer of polyolefin resin is matted, and a subcoat layer mainly composed of gelatin on the resin coating layer on the side where the emulsion layer is provided. In addition, it includes cases in which a back coat layer consisting of a pigment and a binder is provided on the back resin coating layer on the side opposite to the side where the emulsion layer is provided. The present invention is characterized by a method for manufacturing a resin-coated photographic support in which the roughness of the layer is in the range of Ra0 to 10. The present invention also provides a method for producing a resin-coated photographic support in which the roughness of the paper roll is in the range of Ra0 to 20, and the starting torque of the paper roll is 300 g or less.

摩擦係数が０． ６以下に調節されると、写真用支持体
の走行性が改良される。更に好ましくは、静摩擦係数は
０．２〜０．６の範囲である。That is, it has been found that the running properties of the photographic support can be improved by adjusting the coefficient of static friction between the photographic support and the paper roll within the range of 0.2 to 0.6. That is,
Based on this discovery, in the combination of the roughness of the photographic support and the paper roll, the roughness of the photographic support is Ra0 to 10, and the roughness of the paper roll is Ra.
If it is 0 to 20, the coefficient of static friction between the photographic support and the paper roll is 0. When adjusted to 6 or less, the running properties of the photographic support are improved. More preferably, the static friction coefficient is in the range of 0.2 to 0.6.

ーパーロールの静摩擦係数が０． ６より大きくなると
密着性が高くなり、ツレシワが発生してくる。In other words, the runnability of a photographic support is generally determined by the static friction between the photographic support and the paper roll under the conditions that the machine is at its level and the rotation of the paper roll is in sync with the photographic support. The coefficient is 0. If it is larger than 6, the adhesion will be high and wrinkles will occur.
また、静摩擦係数が０． ２より小さいとロールの円周
速度が走行する写真用支持体の走行速度と一致した速度
で回転するに足る充分な摩擦とならないので、樹脂被覆
表面にツレスジが発生してくる。In addition, the static friction coefficient is 0. If it is less than 2, there will not be enough friction to cause the roll to rotate at a circumferential speed that matches the traveling speed of the photographic support, resulting in scratches on the resin-coated surface.

ロール起動トルクは３００ｇ以下が望ましい。In addition, the holding angle between the paper roll and the photographic support is a factor that causes tension in starting the paper roll. The holding angle between the paper roll and the photographic support is 20-1
35°, the tension is preferably 20 to 130 kg/m, and the paper roll starting torque is preferably 300 g or less.
