Abstract: A hydrophilic siloxane copolymer of siloxane and hydrophilic organic monomer/s The copolymers can be functionalized to make them capable of undergoing further polymerization by thermal or actinic radiations. The hydrophilicity of these polymers can be varied by varying the siloxane versus organic monomer ratio thereby going from water dispersible to soluble states. The siloxane content can be tuned accordingly in order to provide moderate to high oxygen permeability. These copolymers can be used as a single component curable composition which results in hydrogels to minimize the presence of leachable components thus by reducing the processing cost. The polymers may also find applications in personal care formulations as copolymers, film-formers, hydrogels, coating, emulsions/latex etc.
Abstract: Provided is a sheet for processing a wafer. The sheet can exhibit excellent heat resistance and dimensional stability, prevent breakage of a wafer in response to residual stress due to excellent stress relaxation properties, inhibit damage to or dispersion of the wafer due to application of a non-uniform pressure, and also exhibit excellent cuttability. The sheet can effectively prevent a blocking phenomenon from occurring during wafer processing. For these reasons, the sheet can be useful for processing a wafer in various wafer preparation processes such as dicing, back-grinding and picking-up.

With this method the material of the resist layer and the conductive layer and the exposure parameters are adjusted to each other such that the resist layer is also exposed outside the area impinged with the electron beam such that the flanks of the relief structure obtain an inclined form.

Furthermore, verification of the sensitive data is performed without necessitating significant mechanical configuration changes or item manipulation techniques.

Abstract: Photothermographic materials are coated with imaging layers and an antihalation layer between the support and thermally developable imaging layers on one or both sides of the support. Such materials can be arranged in association with one or more phosphor intensifying screens capable of providing emission at a predetermined wavelength in imaging assemblies. These imaging assemblies can be exposed to X-radiation and thereby excited to form a latent image in the photothermographic material that can eventually be used for medical diagnosis. The antihalation layers contain radiation absorbing compounds (such as a UV-radiation absorbing compounds) that absorb radiation at the predetermined wavelength (for example at 300 to 450 nm) and have limited absorption at higher wavelengths.

These imaging assemblies can be exposed to X-radiation and thereby form a latent image in the photothermographic material that can eventually be heat developed and used for medical diagnosis. The photothermographic materials contain an opaque material that acts as a crossover control agent that absorbs radiation at the predetermined wavelength, for example at 300 to 450 nm, and has limited absorption at higher wavelengths. When the photothermographic material is heated, the opaque material loses its opacity. Additional crossover control agents, such as UV-absorbing compounds, can also be added to the support or to an antihalation layer.
Abstract: Thermally developable photothermographic materials comprise a backside layer that includes a backside stabilizer to reduce fog formation in high humidity conditions, thereby providing improved shelf stability. Useful backside stabilizers include an amine organic base whose conjugate acid has a pKa greater than 5. These backside stabilizers can be provided particularly in non-photosensitive compositions that include an antihalation composition.
