ABSTRACT:
An opaque polyester film base, coated with several subbing layers, provides a substitute for paper supports currently used for photographic silver halide emulsion films. The film base is energy-treated and then coated sequentially with (1) a white reflective layer comprising titanium dioxide, a polyfunctional aziridine, and an acrylic binder which is crosslinked to the functional groups in the energy-treated base by the aziridine, and (2) an intermediate substratum containing gelatin for anchoring the negative silver halide emulsion.
