Abstract
The invention relates to A reflective base photographic element comprising a support material comprising a microvoided biaxially oriented polymer sheet having an upper surface L* of at least 93.5 and imaging layers wherein said imaging layers have an exposure range of between 125 to 0.5 when there is a Status A reflection density shoulder loss of no more than 8 percent as a function of the cyan record, wherein said photographic element has an exposure range of at least 125 nanoseconds to 0.5 seconds when there is a Status A reflection density shoulder loss of no more than 8 percent as a function of the magenta color record, wherein said photographic element has an exposure range of at least 125 nanoseconds to 0.5 seconds when there is a Status A reflection density shoulder loss of no more than 4 percent as a function of the yellow color record, and wherein said photographic element has a Status A reflection density minimum of less than 0.100 in the cyan layer, has a Status A reflection density minimum of less than 0.100 in the magenta layer, has a Status A reflection density minimum of less than 0.08 in the yellow layer, and a modulation transfer function (MTF) of at least 78.0, an…
