摘要:
A black matrix can be formed by thermal transfer on a receptor substrate for use, for example, in a display application. This black matrix can be used, for example, as a color filter black matrix or a TFT (thin film transistor) black matrix to provide contrast and/or to separate adjacent electrically-conducting components.
摘要:
An optically dispersing film for a rear projection system includes reflecting surfaces disposed so as to reflect light passing therethrough into at least one dispersion plane. The reflecting surfaces are formed by structures, of a first refractive index, disposed within a layer of material having a second refractive index. The structures have light absorbing bases at the viewing side of the film. In some embodiments, the reflecting surfaces are disposed at one or more angles so as to reflect light into a number of different directions. In other embodiments, the layer of material having the second refractive index includes diffusing particles that diffuse the light. The film permits the asymmetric dispersion of image light in a rear projection system, so that the light may be selectively directed towards the viewer.
摘要:
A method of selectively patterning a structured substrate without using a mask is disclosed. The method includes the steps of providing a surface having a plurality of protrusions, coating the surface with a filler material thick enough so that the protrusions are covered, and planarizing the filler coating. The filler material is thereafter partially removed in a uniform fashion to expose only those portions of the protrusions to be modified. After modifying the protrusions by, for example, deposition or etching, the remaining filler material may be removed, resulting in a structured substrate selectively modified or patterned at its protrusions.

摘要:
A gelled dielectric encapsulant material and process therefor for use in reenterable and nonreenterable communication cable splices as well as applications relating to encapsulation of electronic components comprises a plasticizer which does not stress crack polycarbonate, an aliphatic or aromatic carboxylic acid, and a basic oxide or hydroxide.
摘要:
An insulative coating composition for providing water-repellancy to and protecting communication wire comprises an admixture of an anhydride copolymer, a flexibilizing copolymer, a suitable solvent system, a hydrophobic, soluble, compatible fluoroaliphatic radical-containing composition and optionally, a mercaptan, and optionally, an antioxidant. Articles coated with the insulative composition are disclosed.
摘要:
A polyurethane resin is prepared from an aliphatic or cycloaliphatic isocyanate, a polydiol, a tri or tetra functional aliphatic polyol, and a monofunctional aliphatic alcohol, in the presence of a suitable catalyst. The resin exhibits superior adhesion to greasy wires in communication and electrical cable.
摘要:
Antireflective films are described comprising a light transmissive substrate and a low refractive index layer disposed on the light transmissive substrate. The low refractive index layer comprises the reaction product of polymerizable resin composition comprising at least 20 wt-% fumed silica. In one embodiment, the polymerizable resin is ethylenically unsaturated. In a favored embodiment, the low refractive index layer increases in porosity from the light transmissive substrate interface to an opposing porous surface.
摘要:
Presently described are coating compositions comprising a polymerizable resin composition and a non-ionic unpolymerizable surfactant. In some embodiments, the coating comprises greater than 10 wt-% of non-ionic unpolymerizable surfactant. In other embodiments, the coating composition comprises an an additive comprising a silicone group or a fluorinated group and a hydrophobic group. Also described are articles comprising the cured coating compositions. In one embodiment, an article is described comprising a cured coating wherein the cured coating exhibits a property of an initially visible simulated fingerprint reducing in visibility in 1-20 minutes. Also described is a method of determining the fingerprint visibility of a coating composition and a polyacylate composition useful as an additive. In another embodiment a coated surface is described comprising a polymeric organic material comprising a plurality of pores wherein a portion of the pores are interconnected and comprise a lipophilic liquid.
