Abstract
Disclosed is an imaging element comprising a single layer containing a random distribution of a colored bead population of one or more colors coated above one or more layers comprising light sensitive silver halide emulsion grains, wherein the population comprises beads of at least one color in which at least 25% (based on projected area) of the beads of that color have an ECD less than 2 times the ECD of the silver halide grains in said one emulsion layer or in the fastest emulsion layer in the case of more than one emulsion layer
