Various objects may be maintained in their original condition or protected from further damage by physical, chemical, and biological forces by applying thereto thin, continuous, impervious coatings of vapor-deposited poly(p-xylylene) polymer or derivatives thereof. By the invention, it is possible to protect paintings, photographs, documents, articles of sculpture, silver objects, coins, fishing hooks and lures, marine fittings and hardware, batteries, fuel cells, automotive parts, water pollution control devices, logic circuits, electrical components, electric motors and parts, light bulbs, ammunitions, fireworks, glass items, decorative items, timepieces, and decorative wrought iron grillwork.

Articles having thin, continuous, impervious coatings

A method and ink composition for development of an electrostatic latent image with liquid developer is disclosed. The liquid developer has a viscosity suitable for convenient application to an imaged surface in the development of latent electrostatic images and has improved conductivity resulting from incorporating conductivity control agents in the form of quaternary ammonium compounds which are soluble in the carrier of the ink composition. The conductive ink composition comprises a coloring agent, optionally a binder and a dispersing agent, a carrier and a quaternary ammonium compound soluble in the liquid carrier.

Liquid development using conductive inks

A transparency is disclosed, which is suitable for use in a multicolored xerographic reproduction process comprising a transparent, thermoplastic film sheet having at least one surface coated with a long chain aliphatic ester. The ester coated transparency, when used in a multicolored electrostatic copying process improves adhesion of the multicolored image thereon and permits reproduction of colors and color densities in said image which correspond to the multicolored original.

Multicolored xerographic transparency utilizing an aliphatic ester

A method for dyeing hair and other keratinaceous materials with certain amino, hydroxy, methoxy and nitro-containing indoline, indole and indazole compounds, and combinations thereof, and keratinaceous fibers dyed therewith.

Method of dyeing hair with indolines, indoles and indazoles

A transparency is disclosed, which is suitable for use in a multicolored xerographic reproduction process comprising a transparent, thermoplastic film sheet having at least one surface treated with organic amine compounds or salts thereof. The treated transparency, when used in a multicolored electrostatic copying process improves adhesion of the multicolored image thereon and permits reproduction of colors and color densities in said image which correspond well enough to the multicolored original copied.

Transparency treated with organic amine

Conductive inks containing quaternary ammonium compounds

A transparency is disclosed, which is suitable for use in a multicolored xerographic reproduction process comprising a transparent, thermoplastic film sheet having at least one surface coated with a material selected from the group of long chain aliphatic hydrocarbons. The coated transparency, when used in a multicolored electrostatic copying process improves adhesion of the multicolored image thereon and permits reproduction of colors and color densities in said image which correspond well to the multicolored original copied.

Transferring toner to an hydrocarbon sheet

A transparency is disclosed, which is suitable for use in a multicolored xerographic reproduction process comprising a transparent, thermoplastic film sheet having at least one surface coated with a material selected from the group of nonvolatile amine compounds. The coated transparency, when used in a multicolored electrostatic copying process improves adhesion of the multicolored image thereon and permits reproduction of colors and color densities in said image which correspond well to the copied multicolored original.

Transferring toner to an amine coated sheet

An electrostatographic developer mixture comprising finely divided toner particles electrostatically clinging to the surface of larger carrier beads, each of the carrier beads comprising a core particle surrounded by a thin outer layer of a poly(p-xylylene) polymer. Imaging processes of developing electrostatic latent images with the developer mixture are also disclosed.
