The present invention provides methods for controlling the optical properties of a light transmissive article. The method includes identifying a target window in an Abbe diagram comprising reference polymeric materials. The method further includes selecting a first polymeric material from the reference polymeric materials and compounding the first polymeric material with a stable UV chromophore to provide a first polymer composition. The method further includes transforming the first polymer composition to provide the light transmissive article, wherein the light transmissive article has an Abbe number and a refractive index which falls within the target window. Light transmissive articles prepared using the above methods are also provided.

Light transmissive articles and methods thereof

Articles for recording a holographic image are described. The articles include a holographic recording medium having a plurality of surfaces, having a transparent polymeric binder and a photochemically active dye, the holographic recording medium having a holographic image recorded therein formed by exposed areas of the photochemically active dye and unexposed areas of the photochemically active dye; and a first light-blocking layer or material over a first surface of the holographic recording medium from which surface the holographic image is viewed, the light blocking layer or material absorbing light in the wavelength range to which the photochemically active dye is sensitive and allowing transmission of light in a different wavelength range for viewing the holographic image.

Method of making holographic storage medium

A method of making a hologram includes recording a first hologram in a holographic recording medium at a first deformation ratio; changing the first deformation ratio to a second deformation ratio that is different from the first deformation ratio; and recording a second hologram in the holographic recording medium at the second deformation ratio to form a recorded holographic medium.

Complex holograms, method of making and using complex holograms

A method is described for recording a volume reflection holographic image that is viewable when illuminated by light at a wavelength W. The method includes

Reflection hologram storage method

A method of manufacturing an article for display of a holographic image is described that includes thermally fusing a holographic recording medium containing a photochemically active dye dispersed in a transparent thermoplastic polymer binder to another layer or material; and then exposing the holographic film to intersecting beams of coherent light to form a holographic image therein formed by photoreacted areas of the photochemically active dye and unreacted areas of the photochemically active dye.

Method of making holographic recording materials and articles formed thereby

A method of recording a volume holographic image is described in which a holographic recording medium containing a photoreactive dye is exposed to a plurality of coherent light sources emitting at a wavelength to which the dye is sensitive, thereby forming an interference fringe pattern therein. The photoreaction occurring in the areas of constructive interference generates a periodic array of photoreacted areas of the dye and unreacted areas of the dye. This generated interference fringe pattern may contain, but does not have to contain any image or other encoded information. Selected areas of the interference fringe pattern are then exposed to actinic radiation in such a manner to partially or fully bleach, remove, or deactivate the photoreactive dye fringe pattern, thereby producing a holographic pattern, shape, or image formed by areas of the interference fringe pattern that were not bleached, removed, or deactivated.

Holographic storage method

An optical grade article comprises a thermoplastic composition comprising a poly(aliphatic ester)-polycarbonate copolymer comprising 10 to 25 wt % of a soft block ester unit derived from a Caliphatic dicarboxylic acid or derivative thereof, 34 to 77 wt % of a carbonate unit derived from 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine, 0 to 76 wt % of a carbonate unit derived from a dihydroxyaromatic compound not identical to the 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine, wherein the weight percentages of soft block ester units, 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine units, and dihydroxyaromatic compound units is 100 weight percent of the monomeric units of the poly(aliphatic ester)-polycarbonate, the refractive index of the thermoplastic composition is greater than 1.590, and the glass transition temperature of the poly(aliphatic ester)-polycarbonate is from 120 to 155&#xb0; C. A camera lens also comprises the poly(aliphatic ester)-polycarbonate.

A powder coating composition comprises at least one thermosetting resin such as epoxy resins, carboxy- or hydroxy-functional polyesters; hydroxy-, carboxyl- or glycidyl-functional acrylic resins; and/or hydroxy- or carboxyl-functional fluoropolymers, fluorochloropolymers or fluoroacrylic polymers blended with a at least one poly(phenylene ether) and at least one curing agent for the thermosetting resin.

The present invention is directed to a thermoplastic resin composition comprising one or more polyetherimide resins; one or more polyester resins; at least one epoxy compound having one or more epoxy functional groups per molecule in an amount effective to improve at least one of impact resistance, hydrolytic resistance, and tab-bending performance of a molded specimen of the composition; and optionally, at least one catalyst in an amount effective to improve at least one of impact resistance, hydrolytic resistance, and tab-bending performance of a molded specimen of the composition as compared to the same composition not containing the catalyst. It was unexpectedly found that the compositions exhibited enhanced heat, impact, hydrolytic resistance, and/or enhanced tab-bending performance over other compositions known in the art. In a preferred embodiment, the epoxy compound contains 3,4-epoxycyclohexylmethyl-3,4-epoxycyclohexanecarboxylate and the catalyst contains sodium stearate.
