Kodak announced new and definitive enhancements to VISION3 Color Negative films by introducing a new and enhanced VISION3 Camera Negative Film structure – without remjet backing. This new structure incorporates an Anti-Halation Undercoat layer (AHU).
AHU is a gel-based layer that is coated beneath the emulsion layers of the film. It is manufactured as part of the emulsion-coating process and contains silver and other chemical components, which have been scientifically balanced for optimal sensitometric performance. AHU, which is also conveniently removed during processing, requires no workflow adjustments for processing, scanning or printing.
No Remjet: The new AHU layer replaces the traditional remjet backing, a carbon black layer previously used to prevent light halos, resist static, and protect against scratches. The remjet layer required a separate removal step during processing, adding complexity to the workflow.
Simplified Processing: With the removal of remjet, the new AHU film structure allows for processing in standard C-41 chemistry, which is a significant advantage for labs and hobbyist photographers, simplifying the development process.
Improved Anti-Halation and Anti-Static Properties: The AHU layer is a gel-based layer located beneath the emulsion layers that effectively controls halation (light halos) and provides anti-static and scratch-resistance properties that survive the development process.

Cleaner Scans: The anti-static properties of the AHU layer help minimize dust and dirt accumulation, leading to noticeably cleaner digital scans with fewer artifacts.u
Environmental Benefits: Eliminating the remjet layer and the associated removal steps is expected to result in significant reductions in water and energy consumption at labs, according to American Cinematographer.
Same Great Image Quality: Despite these changes, Kodak assures that the AHU version of Vision3 maintains the same high image quality and photographic performance as the original film stock.
Gradual Implementation: Kodak will gradually introduce the new AHU film structure for all Vision3 Color Negative films (including 500T, 200T, 250D, and 50D) across various formats, from Super 8 to 65mm.
No Workflow Adjustments: During the transition period where both remjet and AHU film structures are available, filmmakers can seamlessly combine them in their workflows without needing to adjust their processing, scanning, or printing procedures.
This enhancement represents Kodak's commitment to innovation and addressing the needs of filmmakers, making film photography more accessible and environmentally friendly while maintaining the classic look and quality of Vision3 films.
