  • Patent number: 5585230
    Abstract: Dispersions comprising particles of a phenolic cyan photographic coupler of Formula I dispersed in an aqueous gelatin solution substantially free of permanent organic solvent demonstrate improved stability to dispersion crystallization. ##STR1## R.sub.1 and R.sub.2 in Formula I each represent an aliphatic group, an aromatic group, or a heterocyclic group. R.sub.3 represents a hydrogen atom, a halogen atom, an aliphatic group, an aromatic group, an acylamino group, or a non-metallic atomic group necessary to form a nitrogen-containing 5-membered or 6-membered ring together with R.sub.2. X represents a hydrogen atom or a group capable of being released upon a coupling reaction with oxidation product of a developing agent, and n represents 0 or 1.

  • Patent number: 5541048
    Abstract: 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.
