Ink composition

Reduced nozzle viscous impedance

A recording transparency and method of preparing the same from water solution are disclosed. The transparency is receptive to a wide variety of inks and other indicia, exhibits rapid ink drying times, excellent dot size and shape retention, and excellent water resistance and stability. The transparency comprises a transparent substrate coated from an aqueous solution of a polymeric sorbent selected from synthetic transparent cellulosic polymers, especially one or a mixture of hydroxyethyl cellulose polymers, and a surfactant composition comprising nonionic detergent, anionic detergent and complexing agent.

Recording transparency and method

An ink jet composition and method of printing on plain paper are provided wherein the composition comprises a colloidal solution of a nonaqueous solvent (e.g. selected glycol ethers) and a disperse phase comprising a resin (e.g. a selected ethylene-vinyl acetate copolymer) which is soluble in the solvent at room temperature and a dyestuff which is soluble in the resin at room temperature but substantially insoluble in the solvent at room temperature. The ink composition is fluid and may have a very low viscosity at room temperature.

Room temperature jet printing ink and method

An ink jet ink composition and method of printing on plain paper are provided wherein the composition comprises a mixture of a nonaqueous solvent (e.g. selected glycol ethers), a resin (e.g. an ethylene-vinyl acetate copolymer) which is substantially completely soluble in the solvent at elevated operation temperatures but substantially insoluble in the solvent at room temperature and a dyestuff which is soluble in the resin at room temperature and above but substantially insoluble in the solvent at room temperature. The ink composition is fluid at room temperature, and has very low viscosity at elevated operating temperatures.

Jet printing ink

Jet printing ink compositions characterized as having low volatility, low viscosity and low variation of viscosity with respect to temperature are disclosed. The compositions comprise a coloring agent dissolved or dispersed in a liquid vehicle which is preferably substantially free of added water and is a propylene glycol ether or an ethylene glycol butyl ether in which the coloring agent is soluble or dispersible.

Jet printing ink compositions and methods

An ink jet ink composition useful for printing on plain paper at room temperature comprises a colloidal suspension of a nonaqueous solvent (e.g. selected glycol ethers) and dispersed particles comprising a natural resin or synthetic polymer which is insoluble in water but soluble in the solvent at room temperature, and a dyestuff which is soluble in or bindable to the resin or polymer at room temperature but substantially insoluble in the solvent at room temperature. The ink composition is fluid and has a low viscosity at room temperature.

Room temperature plain paper ink

This invention discloses a new ferrofluid and the use of ferrofluids in magnetically controllable couplings such as electromagnetic clutches and brakes. The new ferrofluid is comprised of a stable suspension of magnetizable particles having a size of at least one micron, a fluid carrier and a complexing agent. The complexing agent maintains the magnetizable particles in suspension within the carrier fluid.

Magnetically controllable couplings containing ferrofluids

Coated paper useful for ink jet printing comprises a cellulosic substrate coated with an intimate mixture of a particulate pigment with a binder comprising a mixture of an acrylic resin and polyvinyl alcohol.
