(57) [Abstract] [Purpose] The occurrence of peeling unevenness during the production of a support for an image material in which the base paper surface on the side where the image forming layer is provided is coated with a polyethylene resin layer is remarkably improved. It is possible to provide an excellent resin-coated paper-type image material support which has a high appearance glossiness, a good image forming layer film adhesion, a good molding processability, and a stable production. In a support for an image material in which a base paper surface on a side where an image forming layer is provided is covered with a resin layer made of a resin composition containing a polyethylene resin as a main component, the polyethylene resin in the resin composition is a metal. A polyethylene resin produced by polymerization using a metallocene polymerization catalyst, and the polyethylene resin component in the resin composition has Mw / Mn (here, Mw: weight average molecular weight, Mn: number average molecular weight) of 5 or more. And a support for an image material. |
