Agfacontour Professional was (as of 2002 not anymore produced [1]) a special emulsion sheet film which, after exposure and development in the Agfacontour developer, produced direct equidensities. Agfacontour was introduced in 1970 by Agfa-Gevaert to produce equidensities by a direct, one-developing-step process.
Aluminium is the most common metal used for deposition, but other metals such as nickel and chromium are also used. The metal is heated and evaporated under vacuum. This condenses on the cold polymer film, which is unwound near the metal vapour source. This coating is much thinner than a metal foil could be made, in the range of 0.5 micrometres ...
Neopan SS was a 100 ISO, fine grain, ortho-panchromatic film with a wide exposure latitude introduced as a roll film in 1952 and 35mm in 1953. The film came with a 2.5 times sensitivity increase in comparison to what Fujifilm was currently producing (SP). Over the years, improvements were made to this film.
The best storage conditions for both black & white and color cellulose acetate film are cold (−15 to 4 °C; 5 to 39 °F) and dry (30% to 40% relative humidity) environments for cellulose nitrate, cellulose acetate films in both color and black and white, and color on polyester supports. [1] Black and white film on polyester supports may be ...
Celluloids are a class of materials produced by mixing nitrocellulose and camphor, often with added dyes and other agents.Once much more common for its use as photographic film before the advent of safer methods, celluloid's common present-day uses are for manufacturing table tennis balls, musical instruments, combs, office equipment, fountain pen bodies, and guitar picks.
Cellulose diacetate film was first created by the German chemists Arthur Eichengrün and Theodore Becker, who patented it under the name Cellit, from a process they devised in 1901 for the direct acetylation of cellulose at a low temperature to prevent its degradation, which permitted the degree of acetylation to be controlled, thereby avoiding total conversion to its triacetate.
"Roll-to-roll" or "web-based" coating is the process of applying a thin film of functional material to a substrate on a roll, such as paper, fabric, film, foil, or sheet stock. This continuous process is highly efficient for producing large volumes of coated materials, which are essential in various industries including printing, packaging, and ...
Acrylic resin is a common ingredient in latex paint (UK: "emulsion paint"). Latex paints with a greater proportion of acrylic resin offer better stain protection, greater water resistance, better adhesion, greater resistance to cracking and blistering, and resistance to alkali cleaners compared to those with vinyl.
