Abstract:
A photopolymerizable composition has five essential components: (a) a photopolymerizable epoxy material, (b) a photoacid generator such as an onium salt, (c) electron donor photosensitizer having an oxidation potential of at least 0.4 V and up to and including 3 V vs. SCE, and (d) metal particles. This photopolymerizable composition can be applied or printed onto one or both sides of various substrates to form articles that can be used to form electrically conductive materials. Methods for using the photopolymerizable compositions include electroless plating methods that can be carried out in roll-to-roll printing systems once various photocured patterns are formed from the photopolymerizable compositions.
Abstract:
Organic polymeric bi-metallic alkoxide or aryloxide composites are used as dielectric materials in various devices with improved properties such as improved mobility. These composites comprise a poly(meth)acrylate or polyester having metal coordination sites, and the same or different bi-metallic alkoxide or aryloxide molecules that are coordinated with the organic polymer. The bi-metallic alkoxide or aryloxide molecules can be represented by Structure (I) shown herein. Such composites are generally soluble at room temperature in various organic solvents and be provided in homogeneous organic solvent solutions that can be suitably applied to a substrate to form dielectric materials.
Abstract:
A thiosulfate polymer composition includes an electron-accepting photosensitizer component, either as a separate compound or as an attachment to the thiosulfate polymer. The thiosulfate polymer composition can be applied to various articles and used to form a predetermined polymeric pattern after photothermal reaction to form crosslinked disulfide bonds, removing non-crosslinked polymer, and reaction with a disulfide-reactive material.
Abstract:
Organic polymeric multi-metallic alkoxide or aryloxide composites are used as dielectric materials in various devices with improved properties such as improved mobility.

An organic film-forming polymer has a Tg of at least 70° C. and comprises a backbone comprising recurring units of Structure (A) shown in this application. These organic film-forming polymers can be used as dielectric materials in various devices with improved properties such as improved mobility.
Abstract:
Porous particles can be prepared using an evaporative limited coalescence process in which one or more discrete cavities are stabilized within the continuous polymeric solid phase of the porous particles. The one or more discrete cavities have inner walls and are dispersed within the continuous polymeric solid phase. The porous particles further comprise a cavity stabilizing hydrocolloid on the inner walls of the one or more discrete cavities, and an amphiphilic (low HLB) block copolymer that is disposed at the interface of the discrete cavities and the continuous polymeric solid phase.
Abstract:
An imaging element is used to provide images based on the difference in index of refraction caused by imaging actinic radiation. Imaging provides desired results by the creation or elimination of light scattering in a two-phase imaging medium in which at least one phase contains a material that is capable of having a refractive index change in response to imaging actinic radiation. For example, if the refractive indices of the two phases are initially matched, imaging can cause a mismatch in imaged regions. Alternatively, the refractive indices of the two phases can be initially mismatched and imaging can create a match of refractive indices in imaged regions. An image can be produced using a controlled amount of imaging actinic radiation without any chemical processing or heating.
Abstract:
Semi-permeable particle can be used to facilitate chemical reactions such as catalytic reactions. The semi-permeable particles are permeable to molecules having a molar mass of 1000 Daltons or less and have a mode particle size of at least 1 μm. The semi-permeable particles have multiple discrete cavities containing an aqueous solution or suspension of an organic catalytic material. The semi-permeable particles are also impermeable to the organic catalytic materials so they are retained within the multiple discrete cavities, and the semi-permeable particles can be reused multiple times for the same or different chemical reaction.
