摘要:
A non-aqueous photocurable composition contains dispersed carbon-coated metal particles in an amount of at least 10 weight %, and the dispersed carbon-coated metal particles have a median diameter of less than 0.6 μm. These particles are dispersed with a particle dispersing agent that has a weight average molecular weight (Mw) of at least 2,000 and up to and including 100,000 and comprises nitrogen-containing units. Such compositions include an organic diluent as well as suitable photocurable components that can be used for example in acid-catalyzed or free radical chemistries. When the non-aqueous photocurable composition contains up to and including 25 weight % of the dispersed carbon-coated metal particles, it exhibits no visual settling when subjected to a settling test of at least 24 hours at 20° C. The non-aqueous photocurable compositions can be used to provide photocured metallic patterns for various devices that have a touch screen display.

A first polymer latex and second polymer latex can be mixed to form a dried primer layer on a substrate to adhere patterned materials having fine lines. The first polymer latex comprises a first polymer and a first surfactant such that a dried coating of the first polymer latex has a surface polarity of at least 50%. The second polymer latex comprises a second polymer and a second surfactant such that a dried coating of the second polymer latex has a surface polarity of less than or equal to 27%. Moreover, a dried coating of the mixture has a surface polarity of at least 15% and up to and including 50%. Primed substrates are useful for preparing electrically-conductive articles having electrically-conductive fine lines directly on a dried primer layer by applying a patterned material to a substrate. Such articles can be used as touch screen displays in various electronic devices.

A laser-engraveable layer is used in a laser-engraveable element to provide relief images. The resulting laser-engraved elements can take various forms and can be used to apply various inks to receiver materials in an imagewise fashion. The laser-engraveable element has a thermally crosslinked laser-engraveable layer containing a crosslinked elastomeric fluoropolymer and a fluoro-functionalized near-infrared radiation absorber. The crosslinked fluoropolymer has a glass transition temperature of less than and including 0° C. and the crosslinked laser-engraveable layer is formed from a reactive fluoropolymer composition comprising a reactive fluoropolymer, the fluoro-functionalized near-infrared radiation absorber, and a compound that causes crosslinking of the reactive fluoropolymer during thermal curing. The reactive fluoropolymer can have a reactive group selected from the group consisting of: poly(tetrafluoroethylene oxide-co-difluoromethylene oxide) α,ω-diol bis(2,3-dihydroxypropyl ether), poly(tetrafluoroethylene oxide-co-difluoromethylene oxide) α,ω-diol, ethoxylated poly(tetrafluoroethylene oxide-co-difluoromethylene oxide) α,ω-diol, and a multifuncational (meth)acrylate end-functionalized derivative of one of such compounds.

Such articles can be used for various purposes including the formation of electrically-conductive grids, and can be incorporated into various devices including those having touch screen displays.
摘要:
A method is used to provide a pattern of a functional material for example on a receiving element. To provide this pattern, a laser-engraveable patternable element is imagewise exposed with laser-engraving radiation. This element has a laser-engraveable layer comprising a thermoplastic elastomeric interpolymer alloy. This interpolymer alloy comprises a non-crosslinked halogenated polymer, a partially crosslinked polyolefin, and a polyester. A laser-engraved patterned element is formed that has a relief image in the laser-engraveable layer, and this relief image can be contacted with a suitable functional material that is then transferred to the receiving element to provide the desired pattern.
