    摘要: An optical article comprising a flexible plastic substrate having an index of refraction ranging from 1.55 to 1.71 and having first and second surfaces and an anti-reflection coating carried by the first surface. The anti-reflection coating consists of a high index material and a low index material in which the high index material has an index of refraction of 2.0 and greater to provide the index of refraction difference between the substrate and the high index material of 0.29 to 0.75. The low index material is formed of a material having an index of refraction of 1.38 or less to provide an index of refraction difference between the high index material to the low index material ranging from approximately 0.59 to 0.92.

    摘要: Flexible polymer packaging films having thin films of inorganic coatings deposited thereon to reduce the vapor permeability of the article. Inorganic thin film coatings comprising a composite of two materials are disclosed to confer both substantial transparency and retortability on the overall packaging film structure. The two material film composite involves either sequentially deposited films with the first thin film layer serving as an adhesion layer and the second thin film layer serving as a barrier layer. Alternatively, the two materials may be co-deposited to form a single thin film layer which provides sufficient adhesion to confer retortability on the overall film structure and also functions as relatively impermeable gas and vapor barrier for reducing the vapor transmission rate through the product. Various coated single film articles and dual film laminated articles are disclosed.
