ABSTRACT:
A paper material for photosensitive materials consisting essentially of a paper support and a coextruded multilayer extrusion laminating layer laminated onto the paper support. The coextruded multilayer extrusion laminating layer has an adhesive layer comprising less than 5 wt. % of carbon black and 5 to 90 wt. % of acid-modified adhesive polyolefin resin that is adhered to the paper support and a surface layer comprising less than 3 wt. % of carbon black and more than 10 wt. % of ethylene copolymer resin. The paper material does not induce fogging, sensitivity deviation or the like upon photosensitive materials and has a great adhesive force between the paper support and the resin layer. A method for producing the paper material. is also disclosed.
