This invention contemplates droplets of liquid lubricant, each droplet coated with colloidal particulate suspension stabilizing agent. The invention also contemplates a method of making size stable lubricant droplets by forming a discontinuous phase of lubricant droplets in a continuous aqueous phase containing a particulate suspension stabilizing agent, reducing the size of the lubricant droplets and limiting the coalescence of the lubricant droplets by action of the particulate suspension stabilizing agent. A third aspect of the invention is an imaging element comprising a support, at least one light-sensitive layer and a protective layer further removed from the support than the light-sensitive layer, at least one layer containing droplets of lubricant coated with colloidal particulate suspension stabilizing agent.

Lubricant particles, method of preparation, and photographic elements

This invention provides polymeric particles uniformly coated with colloidal cupric oxide particles by forming a suspension of polymer particles as a discontinuous phase in a continuous aqueous phase containing a colloidal cupric oxide suspension stabilizer.
