Micro-thin layers of gelatin on film in which light-sensitive ingredients are suspended; triggered by light to create a chemical reaction resulting in a photographic image
a suspension of droplets of one liquid in another liquid (such as oil and water) The two liquids do not actually combine but are instead suspended within one another
An emulsion can be formed from the correct mixture of oil, water and surfactant In the emulsion phase the oil and water will not separate Common examples of emulsions include mayonaise and various salad dressings See also microemulsion
a mixture of liquids that do not dissolve in each other to form a true solution, but have droplets of one liquid dispersed throughout the other For MRF it is generally an oil and water mix Emulsifier--a substance added to soluble oil MRF to aid in forming an emulsion in the fluid see above O
A mixture (usually milky-white) in which one liquid is dispersed (but not dissolved) in another A latex paint or caulk binder is often referred to as an emulsion, even though it is a dispersion of solid polymer particles in a liquid (water) In Europe, latex paints are often referred to as "emulsion paints "
A suspension of small droplets of one liquid in an another in an which it is insoluble For the formation of a stable emulsion, an emulsifying agent must usually be present
The emulsion forms the light sensitive part of film or paper The film base is usually polyester or tri-acetate which is then coated with a layer or layers of an emulsion made up of silver halide crystals in gelatin
A suspension of a light-sensitive material (salt of silver) in a colloidal medium (usually gelatin) used to coat photographic film, printing plates or paper In popular usage, any coating, whether or not it is photo-sensitive
Light-sensitive silver halides mixed with additives and gelatin that are coated on a film or paper surface to create photographic film or printing paper
An emulsion is a liquid or cream which is a mixture of two or more liquids, such as oil and water, which do not naturally mix together. Mixture of two or more liquids in which one is dispersed in the other as microscopic or ultramicroscopic droplets (see colloid). Emulsions are stabilized by agents (emulsifiers) that (e.g., in the case of soap or detergent molecules) form films at the droplets' surface or (e.g., in the case of colloidal carbon, bentonite clay, proteins, or carbohydrate polymers) impart mechanical stability. Less-stable emulsions eventually separate spontaneously into two liquid layers; more-stable ones can be destroyed by inactivating the emulsifier, by freezing, or by heating. Polymerization reactions are often carried out in emulsions. Many familiar and industrial products are oil-in-water (o/w) or water-in-oil (w/o) emulsions: milk (o/w), butter (w/o), latex paints (o/w), floor and glass waxes (o/w), and many cosmetic and personal-care preparations and medications (either type)
The light-sensitive layers (basically silver halides in gelatin) forming the pale side of the film After processin, the emulsion carries a permanent, visible image
a light-sensitive coating on paper or film; consists of fine grains of silver bromide suspended in a gelatin (chemistry) a colloid in which both phases are liquids; "an oil-in-water emulsion
Any liquid preparation of a color and consistency resembling milk; as: (a) In pharmacy, an extract of seeds, or a mixture of oil and water united by a mucilaginous substance
A mixture of two materials, where micron scale particles of a solid or liquid are dispersed in a liquid where it does not dissolve Common emulsions have oil dispersed in water (e g milk and mayonnaise) or water dispersed in oil (margarine) Common cleaning agents and greases are also emulsions Stable emulsions require the presence of a surface active agent (surfactant), often a detergent or soap, that accumulates at the interface between the two kinds of materials
Emulsion is a suspension containing one component (e g oil) suspended within a second component with which it will not naturally mix or dissolve into (e g water) All Nikwax WaterBase products are oil in water emulsions Salad dressing is an example of water in oil emulsion
Emulsion or emulsion paint is a water-based paint, which is not shiny when it dries. It is used for painting walls and ceilings. an undercoat of white emulsion paint. a matt emulsion
Used alternately with film, but refers to the coating on the acetate film base Emulsions consist of light-sensitive silver salts, color couplers, filters, and other layers that work together to both protect and form the actual photographic image on film
The light-sensitive layer of film or paper In black and white films the emulsion usually consists of very fine grains of silver halide suspended in gelatin, which blacken when exposed to light The emulsion of color films contains molecules of dye in addition to the silver halide
