3m Introduces New Protective Coating for Motion Pictures

Article excerpt

A process designed for the protection of internegatives and prints in all film formats, that not only extends their useful life, but retains the clarity of image without scratches or dust.

A protective coating for professional motion picture film which reduces scratches, thereby extending the life of the film has been introduced by the 3M Photographic Products Division.

Originally developed to coat plastic lenses used for light-emitting diode displays on wrist watches, 3M's patented PHOTOGARD coating came to the motion picture industry several years after discovery in the company's Central Research Laboratory.

Colorless, clear and flexible, PHOTOGARD coating is applied to motion picture or still film, negative or positive, to protect against scratches, static electricity, spills, smudges and cracks. An additive to the PHOTOGARD coating applied to color paper prints significantly reduces color dye fade caused by ultraviolet exposure.

Applications for PHOTOGARD coating are numerous, and fall into four basic categories:

1) Motion Pictures-PHOTOGARD coating is used to protect internegatives and release prints of 70mm and 35mm theatrical releases, 16mm industrial and commercial films, and Super-8 point-ofpurchase films.

2) Graphie Arts-PHOTOGARD was recently introduced as a coating for typesetting film fonts. Also, the coating may be used to protect halftone screens, printed circuit negatives and positives, printed matter that is exposed to the elements or possible defacing (e.g. subway maps), and bar code labels to maintain information readability.

3) Photofinishing - PHOTOGARD coating can provide a clear, tough coating for amateur snapshots, professional and commercial prints, school and other group photos and portraits.

4) Micrographics - PHOTOGARD coating can be used to protect conventional 16mm and 35mm rolls of microfilm and sheets and rolls of 105mm microfiche.

The PHOTOGARD coating is applied to both sides of motion picture film at a new 3M coating facility in New York City. The coating is designed for protection of internegatives and release prints of 70mm and 35mm theatrical releases, 16mm industrial and commercial films, and Super-8 point-of-purchase films.

The protective coating prevents a wide variety of physical damage to release prints and laboratory intermediate stocks. The 3M PHOTOGARD service will provide a rapid turn-around coating service to the trade, according to John M. Lupo, 3M's market development manager for Abrasion Resistant Products, St. Paul, Minn.

"PHOTOGARD has been tested successfully by several of the largest film makers in the nation," Lupo said. "We have discovered a potential use beyond our original expectations. The coating not only extends the life of prints, thus providing a production cost saving, but it retains the clarity of the image, without scratches or dust, from the first showing to many hundreds of screenings. …
