Physical Properties

• Hardened emulsion for high-temperature rapid processing and resistance to abrasion
• Antihalation undercoat
• Meets ANSI and ISO standards for archival storage media

Nominal Thickness Data (Unprocessed)

• Support: 4.0 mils, Estar Base
• Total Film Thickness: 4.0 +/- 0.2 mils

Before-Process Handling

• Unprotected films should be handled in total darkness or under safelight conditions (such as a Kodak No. 2 Safelight Filter - dark red, or a Kodak No. 1 Safelight Filter - red), with a 15-watt bulb at least four feet from the film.
• Com-Pack Cartridge may be handled in room light.
• Roomlight Load may be handled in room light.

Before-Process Storage

• Keep unprocessed film in the original, unopened package at 70 degrees Fahrenheit (21 degrees Celsius); 50% relative humidity or below; and protected from radiation and X-rays.
• To avoid moisture condensation on film that has been refrigerated, do not open the package until the film has warmed throughout to normal room temperature (about three hours if refrigerated, and five hours if frozen).

Photographic Properties

• Fine grain
• Excellent dimensional stability
• Medium contrast
• Excellent latent-image keeping
• High resolving power (resolving power based on recommended process)

Test-Object Contrast

• 1.6:1 (ISO-RP) - 100 line pairs/mm
• 1000:0 (ISO-RP) - 400 line pairs/mm

These values were determined by a method similar to the one described in ISO Standard 6328-1982, "Photography - Photographic Materials - Determination of ISO Resolving Power", except the light source used was a high pressure mercury vapor arc.

Diffuse RMS Granularity

• Granularity: 6

Read at net diffuse visual density of 0.30 using a 48-micrometer aperature. A more detailed discussion of granularity can be found in Kodak Publication F-20, "Understanding Graininess and Granularity".

Processing Information: Processors and Processing Chemicals

• COM DR 2467 Microfilm can be processed in most typical continuous-strand type medium- and deep-tank processors (such as Allen F10, F-10R, F-20, F-20R, Houston Fearless 76, Oscar, Jamieson, Hollywood, Kodak Versamat 75, and others utilizing Kodak COM Professional Developer and Replenisher DRC with Kodak Microfilm Fixer and Replenisher).
• COM DR 2467 Microfilm is compatible with all standard microfilm processing equipment and high quality microfilm chemicals, although results may vary.

IMPORTANT: For best results, and to avoid aeration, always add chemical concentrate to water -- not water to concentrate.

Photographic Aims

• D-max: 1.95 to 2.15. (When starting with fresh chemicals, D-max may be slightly lower than 1.95 until the chemicals are seasoned.)
• D-min: .06 or lower.
• Processor transport speed and/or temperature may be varied to achieve D-max and D-min values. Process adjustments to achieve a D-max in the range of 1.95 to 2.15 or lower D-min may be required, depending on unique processing situations. Initial D-max on startup of fresh developer may be slightly lower, but should stabilize in the 1.95 to 2.15 range.
