A photopolymerizable composition for use in forming a photopolymer composition for use in forming the light transmissive regions of light transmissive devices, and such devices. The photopolymerizable composition comprises one or more ethylenically unsaturated monomers selected from the group consisting of aryl acrylates and aryl methacrylates and preferably multi-functional aryl acrylates and aryl methacrylates such as aryl triacrylates, aryl diacylates, and aryl tetraacrylates; and a photoinitiator that activates polymerization of the unsaturated monomers upon exposure to actinic radiation. The composition may be polymerized to form a photopolymer which on exposure to a temperature of 190.degree. C. in air for 24 hours exhibits a coloration on the Gardner Color Scale equal to or less than 8 as determined by ASTM D1544-80 and which exhibits no cracking or delamination from a glass substrate as defined by ASTM D4538-90A on exposure of the same to a temperature of 190.degree. C. for 24 hours in air.

Thermally-stable photopolymer composition and light transmissive device

Optically active (optically non-linear or electro-optically active) waveguides are formed by depositing a layer of organic material, typically polymeric material, comprising one or more opticaly active components, and subjecting predetermined regions of the layer to actinic radiation to alter the refractive index of these regions.

Method for forming optically active waveguides

The present invention includes a polarizer element and an array of tapered waveguides in substantial contact with the polarizer element. The tapered end of each of the waveguides extends outward from the polarizer element. Each of the waveguides has a light input surface adjacent the polarizer element and a light output surface distal from the light input surface. The area of the light input surface of each of the waveguides is greater than the area of its light output surface. Also, the waveguides in the array are separated by interstitial regions with a lower refractive index than the refractive index of the waveguides. The present improved polarizer may be used in display devices, such as projection display devices, off screen display devices, and direct view displays. Such displays are used in a wide range of applications including computer terminals, airplane cockpit displays, automotive instrument panels, televisions, and other devices that provide text, graphics, or video information.

A direct view display including a light generating means for generating light, a modulating means for modulating light from said light generating means to form an image, and an image display means for displaying said image from said modulating means positioned adjacent to the light output surface of said modulating means, said display means comprising an array of tapered optical waveguides on a planar substrate the tapered end of each of said waveguides extending outward from said substrate and having a light input surface adjacent said substrate and a light output surface distal from said light input surface. The area of the light input surface of each waveguide is greater than the area of its light output surface, and the center-to-center distance between the light input surfaces of adjacent waveguides in said array is equal to the center-to-center distance between the light output surfaces thereof, so that the angular distribution of light emerging from the output surfaces of the waveguides is larger than the angular distribution of light entering the waveguides. Also, the waveguides in said array are separated by interstitial regions with a lower refractive index than the refractive index of said waveguides.

The present invention is directed to a process for making an array of tapered photopolymerized waveguides. A photomask having opaque and transparent regions is placed in substantial contact with a substrate having a substantially uniform thickness of photopolymerizable mixture thereon. The photopolymerizable mixture is then exposed through the transparent regions of the photomask to substantially collimated actinic radiation for a time sufficient to form an array of tapered photopolymerized waveguides. The photomask and photopolymerizable mixture which was not substantially polymerized by the substantially collimated actinic radiation are then removed from the substrate. The tapered waveguides are useful as a display means in direct view devices and projection display devices.

Solid bodies having a reflective surface are provided with an anti-reflection coating of a terpolymer composition derived from (a) perfluoroalkylalkyl acrylate or methacrylate, (b) acrylic, methacrylic or itaconic acid, and (c) hydroxyl- containing acrylate or methacrylate.

Polymeric anti-reflection coatings and coated articles

A new monomer is used to prepare homo or copolymers containing blocked imide groups which are characterized by deblocking in two stages, first when acid catalyzed and thereafter in aqueous alkaline solutions. Such polymers are, therefore, especially useful in formulating positive photoresist compositions. The polymers are combined with a latent photoacid, which when exposed to actinic radiation removes the acid sensitive blocking moiety, preferably an acetal or ketal group, leaving a methylol group or substituted methylol group remaining attached to the nitrogen atom, which groups are subsequently removed by exposure to aqueous alkaline developing solutions, leaving only imide groups. ##STR1## The new monomer is a derivative of maleimide in which the imide hydrogen has been replaced with a methylol group, which is subsequently reacted to form an acetal or ketal. Preferred monomers include N-(2,4-dioxa-3,3-dimethylpentyl)-2H,5H-2,5-dioxopyrrole and related compounds.
