  • Laminate and method for protecting photographic element
    Patent number: 4077830
    Abstract: A laminate having particular characteristics is used in securing a protective sheet over the emulsion surface of a photographic element such as negatives, positives, slides, glass plates, microfilm, movie film, etc. The optical and mechanical characteristics of the laminate include a protective sheet of transparent, wear-resistant plastic coated with a pressure-sensitive adhesive so that the total thickness of the protective sheet and the adhesive is less than 0.004 inches. The adhesive transmits a major portion of incident ultra violet light and is non-degradable in ultra violet light, and a release sheet of resin material covers the adhesive coating until application to the photographic element when the release sheet is stripped away. Both the protective sheet and the release sheet have a surface finish of less than 10-millionths of an inch RMS so that both the adhesive surface and the protective sheet surface are very smooth when the release sheet is stripped away.
