Abstract
The present invention describes an aqueous coating composition useful in an imaging element which includes polymeric matte beads, an ionic surfactant and a dispersant selected from the group of polymers represented by the generic structures shown below ##STR1## wherein A comprises up to 150 repeat units of ethylene oxide, B comprises 3 to about 100 repeat units of a propylene oxide or higher alkylene oxide or combinations thereof, Q represents a multivalent linking group, x represents 1 or 2 and z represents 1 or 2. The present invention describes an imaging element that includes a support, at least one image-forming layer, and an auxiliary layer of polymeric matte beads, an ionic antistatic agent, and a dispersant selected from the group of polymers represented by the generic structures shown below: ##STR2## wherein A is up to 150 repeat units of ethylene oxide, B is 3 to about 100 repeat units of a propylene oxide or higher alkylene oxide or combinations thereof, Q represents a multivalent linking group, x represents 1 or 2 and z represents 1 or 2. The present invention also describes an aqueous coating composition useful in an imaging element.
