Characteristics
ScotchChrome™ 400 is a new color reversal film designed to give excellent results when used at exposure indexes of 400 to 3200.
This film exhibits excellent color reproduction and color purity, optimal image structure and storage characteristics.
The extended processing latitude yields minimal changes in color balance, maximum density, and image characteristics at specified push processing times.
ScotchChrome 400 is balanced for daylight or equivalent light of 5500K and is an ideal choice for existing light photography, dimly lighted subjects, sports and fast action photography, or other broad applications in amateur, professional, commercial and industrial photography.
General Properties
Speed:
ISO 400 for exposure in the range of 1/2 to 1/10,000 second.
Image characteristics:
Excellent sharpness and fine grain ensure optimal reproduction of the original scene at various film speeds.
Color reproduction:
Optimal yellow sensitization and newly formulated cyan and magenta couplers provide brilliant and saturated colors. The new colorimetric characteristics ensure compatible performance in printing and graphic arts applications.
Storage characteristics:
The emulsion shows great stability and protection against noxious agents caused by improper storage (high temperature, high humidity, fumes, etc.) to ensure consistent quality throughout the product life.
Dye stability:
High resistance to dye fading and superior dark storage characteristics.
Process E-6 compatibility:
ScotchChrome 400 is fully compatible with E6 processing.
Push processing:
Features incorporated in this film deliver quality results using established push processing procedures with minimal change in color balance and maximum density.
Exposure
This film is balanced for daylight or equivalent light conditions with an average color temperature of 5500K.
Important: Expose entire roll at one speed index only. Mark the cassette with the speed you used to ensure appropriate processing.

Reciprocity
For exposure times longer than 1/10 second, it is necessary to compensate for reciprocity characteristics.

Exposure and Processing Times
This film is intended for standard E6 processing or using established E-6 push processing procedures. The features of this film make it possible to use it at specified exposure indexes from 400 to 3200 and to compensate by changing first developer times with minimal change in color balance, grain and maximum density. We suggest, as a starting point, the following modification to the processing time:
| Exposure Index | Process | Suggested First Developer Time |
| 3200 | Push P3 | 15 minutes |
| 1600 | Push P2 | 12 minutes |
| 800 | Push P1 | 9 minutes |
| 400 | E-6 Process | 6 minutes |
Important: In order to ensure appropriate processing of your film, mark the cassette with the ISO speed you used and communicate to the laboratory the push process required.
Storage of Films Prior to Processing
Like all color films, ScotchChrome™ 400 is sensitive to heat, humidity and fumes from chemicals.
Always store unexposed or exposed films in a cool, dry and dark place in moisture-proof containers.
Use film before the expiration date printed on the box.
Do not open the original sealed container until just before using the film.
Avoid leaving film and loaded cameras near heat sources or in hot places such as in a car parked in the sun.
Avoid storing unpackaged film and loaded cameras in high humidty conditions or where the emission of exhaust gases and formaldehyde fumes may occur as these are very harmful to photographic films (aldehyde fumes are often emitted from new furniture, wood glues, laminate adhesive, foam insulation, perfumes, deodorants, aerosol sprays, etc.).
Avoid leaving a partially exposed roll of film in the camera for a long period of time.
Process exposed films promptly to avoid any image deterioration.
In hot, humid climates, keep unexposed and exposed films in a refrigerator in a moisture-proof container at 10°C/50°F or lower with a drying agent such as silica gel.
Storage of Processed Films
The dyes in ScotchChrome 400 are among the most stable used for sensitized material. Yet, like all organic dyes, they may change with time. Humidity, heat and light are the most critical factors in the storage of processed color films. Always keep processed films in a cool, dry, dark place. It is advisable to store processed film at a relative humidity not exceeding 40% and a temperature not exceeding 20°C/68°F.
Handling
Always handle this film in subdued light when loading or unloading the camera.
Darkroom Handling
ScotchChrome 400 film must be handled in complete darkness.

Note: The sensitometric curves and data represent product tested under the conditions of exposure and processing specified. They represent production coatings and, therefore, do not apply directly to a particular box or roll of photographic material. They do not represent standards or specifications which must be met by Imation. Imation reserves the right to change and improve product characteristics at any time.
