Abstract: The present invention is an imaging element which includes a support, at least one imaging layer superposed on the support and a protective topcoat superposed farthest from the support. The topcoat includes a binder and lubricant droplets. The lubricant droplets are composed of a lubricant and a water soluble polymer containing heterocyclic aromatic nitrogen groups wherein the droplets are surrounded by a particulate stabilizer. The present invention is also directed to the lubricant droplets.

Abstract: A method is provided for lubricating a die cavity that includes applying a lubricant composition containing a high melting point polymeric wax lubricant to the wall of a die cavity. Preferably, the lubricant is a polyamide lubricant that has a melting temperature greater than the temperature of the die wall during use. The present invention also provides a method of making a compacted metal part that includes applying the lubricant composition to an internal wall of a die cavity, introducing a metal-based powder composition into the die cavity; and compacting the powder composition at a pressure sufficient to form a compacted part from the metal powder composition.

Abstract: A dye composition has the formula: ##STR1## where R.sup.1 and R.sup.2 are the same or different and are selected from (A) C.sub.2 -C.sub.12 alkyloxyalkyl, and (B) C.sub.9-12 alkyl, (A) comprising from about 30 to 80 mole % of the R groups, (B) comprising 20 to about 70 mole % of the R groups. The dye composition is useful as a fluorescent tracer in refrigerant lubricants of the polyol ester types used in non-Freon refrigerants.

Abstract: 1,8-Naphthalimide derivatives of Formula (I) are useful as fluorescent dyes: ##STR1## wherein R.sup.1 and R.sup.2 are each independently selected from the group consisting of branched alkyl groups containing 7-8 carbon atoms and alkyloxyalkyl groups containing 4 to 24 carbon atoms.
