ANTIREFLECTION FILM
First Claim
1. An antireflection film comprising a substantially transparent substrate bearing a polymeric antireflection layer, the antireflection layer forming one outer surface of the antireflection film and having a refractive index at least about 0.02 less than that of the substrate over the wavelength range of 400 to 700 nm, the antireflection layer being formed from a cured polymer comprising repeating units derived from a fluoroalkene, an alkyl acrylate or methacrylate and a polyfunctional acrylate monomer, there being no inorganic antireflection layer present between the substrate and the polymeric antireflection layer.

Abstract
An antireflection film comprises a transparent substrate carrying on one surface a polymeric antireflection layer, this antireflection layer having a refractive index at least about 0.02 lower than that of the substrate and being formed from a cured polymer comprising repeating units derived from a fluoroalkene, an alkyl acrylate or methacrylate and a polyfunctional acrylate monomer. No inorganic antireflection layer is present between the substrate and the polymeric antireflection layer.

15. A process for providing a polymeric antireflection film on a substantially transparent substrate, the substrate being free from inorganic antireflection layers, the process comprising:
-
depositing a layer of a curable composition on the substrate, the curable composition comprising a polymer of a fluoroalkene, a polymer of an alkyl acrylate or methacrylate, and a polyfunctional acrylate monomer; and
effecting free radical curing of the deposited curable composition to form a polymeric antireflection layer having a refractive index at least about 0.02 less than that of the substrate over the wavelength range of 400 to 700 nm. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

28. A photographic product for forming a diffusion transfer image and comprising:
-
a photosensitive element comprising at least one photosensitive layer having associated therewith an image dye-providing material, the photosensitive element being such that upon its exposure to light and contact with an alkaline developing composition, an image dye is released from non-exposed regions of the photosensitive element; and
an image-receiving element in superposed relationship with the photosensitive element so as to receive image dye released from the photosensitive element and thereby form an image, the image-receiving element bearing, on its surface remote from the photosensitive element, a polymeric antireflection layer having a refractive index at least about 0.02 less than that of the image-receiving element over the wavelength range of 400 to 700 nm, the antireflection layer being formed from a cured polymer comprising repeating units derived from a fluoroalkene, an alkyl acrylate or methacrylate and a polyfunctional acrylate monomer.
