ABSTRACT:
Resin coated photographic base paper having improved stiffness is made by co-extruding a face side resin coating having a first layer of pigmented LDPE and over it a thin layer of a stiff polymer, especially polycarbonate. An intermediate layer of a strongly adhesive polymer may be included to enhance bonding between the first and second layers. The base paper may also have a co-extruded wire side resin coating with a stiff polymer second layer.
