A coating composition which imparts antifog, antireflective, easy-cleaning, and/or antistatic properties to substrates coated therewith. The coating compositions utilize nanoparticles functionalized with amine groups and/or protected amine groups, and amine-reactive groups.

Hydrophilic coatings, articles, coating compositions, and methods

A protected polymeric film comprises a polymeric film substrate having a first major surface and a second major surface opposite the first major surface, and a protective structure provided on at least the first major surface of the substrate, wherein the protective structure comprises a layer of boron oxide and an inorganic barrier layer. A protective structure may also be provided on the second major surface of the substrate. Organic electronic components may be formed on or attached to the protected polymeric films.

Protected polymeric film

An organic electroluminescent device comprises a substrate that supports a first electrode, a second electrode, and a light emitting structure that is disposed between the first and second electrodes. A protective structure comprising a layer of boron oxide and an inorganic barrier layer cooperates with the substrate to encapsulate the first electrode, the second electrode, and the light-emitting structure.

A coating composition which imparts anti-reflective and anti-fog properties to substrates coated therewith. The coating composition utilizes an inorganic metal oxide in combination with silane or a siloxane oligomer. The coating compositions are particularly useful in the manufacture of disposable surgical masks and face shields.

Coating composition having anti-reflective and anti-fogging properties

Compositions containing conductivity enhancers, which are capable of being coated onto a substrate by means of electrostatic assistance. The compositions comprise one or more cationically polymerizable monomer(s), one or more cationic initiator(s), and one or more non-volatile conductivity enhancer(s) having anionic and cationic portions which are soluble in the monomer(s) and which do not interfere with cationic polymerization wherein the anionic portion is a non-coordinating carbon-containing anion. The compositions may further comprise one or more dissociation enhancing agent(s), oligomer(s) or polymer(s), preferably co-reactive, free-radically curable monomer(s), free-radical generating initiator(s), leveling agents, and other additives or adjuvants to impart specific properties to the polymerized composition.

Compositions containing conductivity enhancers, which are capable of being coated onto a substrate by means of electrostatic assistance. The compositions comprise one or more free-radically curable monomer(s), and one or more non-volatile conductivity enhancer(s), having cationic and anionic portions, which are soluble in the monomer(s) and which do not interfere with free-radical polymerization, wherein said anionic portion is a non-coordinating organophilic carbon-containing anion. The compositions may further comprise one or more initiator(s), one or more dissociation enhancing agent(s), cross-linking agent(s), cationically polymerizable monomer(s), cationic initiator(s), leveling agents, oligomer(s) or polymer(s), preferably co-reactive, and other additives or adjuvants to impart specific properties to the cured coating.

Free-radically polymerizable compositions capable of being coated by

A coating composition which imparts anti-reflective and anti-fog properties to substrates coated therewith. The coating composition utilizes an inorganic metal oxide in combination with silane or a siloxane oligomer. The coating compositions are particularly useful in the manufacture of disposable surgical masks and face shields. Methods of coating are also disclosed.

Nonlinear optical (NLO) compositions are disclosed which contain polar disulfone-functionalized molecules (PDFMs) incorporated in a polymeric material. when aligned noncentrosymmetrically in the polymeric material, the PDFMs generate a second-order NLO response. There is also disclosed: a method of preparing a NLO composition; novel PDFMs and novel polymers; and a new process for preparing PDFMs.

Positive-acting no-process printing plates are disclosed in which a stable visual or print-out image is obtained upon exposure of the plate to actinic radiation. The visual image is obtained by incorporation into the photosensitive layer, a dye which is irreversibly bleached upon exposure of the printing plate. For example, an acid which is generated upon exposure of a photopolymer to radiation may be used to bleach a dye of this invention. The visual or print-out images produced are useful in the production cycle and are stable to basic environments that may be encountered in the production setting.

Visible image dyes for positive-acting no-process printing plates

The present invention provides novel dental impression materials, the cure of which can be monitored visually, comprising: (1) a curable silicone polymer; (2) a crosslinker compound containing silicon-bonded-hydrogen groups; (3) a hydrosilation catalyst; and (4) one or more cure-indicating dyes that exhibit a color change in the presence of a silicon-bonded-hydrogen compound and a hydrosilation catalyst. The cure-indicating dye provides the composition with an initial pre-cure color and a different post-cure color. As a result of this change in color, the state of cure of the impression material can be visually monitored.
