Abstract:
1. A method of producing a resin-coated-paper-based support for an imaging material having the support and an image-forming layer, which support comprises a base paper made of a natural pulp as a main component and at least three resin layers coated on a side of the base paper where an image is to be formed, said at least three resin layers including a lowermost layer formed on the base paper, an intermediate layer formed on the lowermost layer and an uppermost layer formed on the intermediate layer, the method comprising coating at least one resin layer for the lowermost layer on the base paper by melt extrusion, and then coating resin layers for the intermediate layer and the uppermost layer on the lowermost layer by concurrent extrusion to form a multi-layered resin layer on the base paper, wherein the uppermost layer is coated at a temperature lower than a temperature at which the lowermost layer is coated and the support is reduced at a production rate or base paper running rate of at least 250 m/minute.
