    摘要: The invention relates to a photographic element comprising a paper base, at least one photosensitive silver halide layer, a layer of microvoided polymer sheet between said paper base and said silver halide layer, and one or more other non-voided layers between said silver halide layer and said microvoided layer, and one or more other non-voided layers between said mirovoided layer and said paper base.The voided or non-voided layers have levels of TiO.sub.2 and colorants adjusted to provide optimum optical properties for control of MTF, LSTAR, and OPACITY.
