The present invention is a amorphous saturated hydrocarbon thermoplastic substrate having enhanced adhesion properties, wherein the enhanced adhesion properties are obtained by treating the surface of the amorphous saturated hydrocarbon thermoplastic substrate with an excited gas phase technique, such that a critical surface energy of at least 35 dyne/cm is obtained without the use of acids or other corrosive materials which cause equipment degradation.

Adhesion of amorphous saturated hydrocarbon thermoplastic substrates

The present invention relates to crosslinkable thermoplastic compositions comprising a plurality of crosslinkable moieties, capable of undergoing addition polymerization, incorporated by functionalization of the precursor poly(hydroxy ethers). The poly(hydroxy ethers) comprise recurring moieties derived from aromatic dihydroxy compounds. The crosslinkable polymeric compositions are crosslinked to obtain crosslinked thermoset polymeric compositions of the invention. The polymeric compositions of the inventions can be suitably used either as an active guiding layer, and/or as a NLO active upper and lower cladding layers in an electro-optic device. The polymeric compositions can also be used as non-NLO polymers for the upper and lower cladding layers, prior to orientation by the application of an electric field.

Crosslinkable thermoplastic and crosslinked thermoset nonlinear optical

The present invention is a liquid crystal display device comprising a color filter which comprises: a) a transparent substrate; b) an opaque material disposed as a pattern on a major surface of the substrate, which pattern defines borders within which a coloring agent or agents can be received; c) a silicate layer superposing the opaque material, the silicate layer having reactive sites; d) a sufficient concentration of organosiloxane groups bonded to the reactive sites of the silicate layer to render the opaque material dispersion inhibiting; and e) at least one coloring agent disposed within the borders defined by the opaque material. In another aspect, the present invention is a method of preparing a color filter for a liquid crystal display device that comprises organosiloxane groups bonded to the surface of a black material disposed on a transparent substrate in such a manner as to form borders for wells or channels adapted to receive coloring materials, the bonded organosiloxane groups being prepared by the steps of: a) exposing the black material to a silicon tetrahalide and sufficient water to form a silicate layer on the opaque material; b) contacting the silicate layer with an organosiloxating reagent to form organosiloxane groups bonded to the silicate layer; and c) disposing a coloring agent into at least one well or channel. The present invention provides an effective means of creating dispersion-preventing patterns for color filters in LCDs.

The present invention is directed to epoxy-based polymeric nonlinear optical materials in which a nonlinear optical active moiety or functionality forms the crosslink between polymer chains and a process for making the nonlinear optical (NLO) epoxy polymer including heating an epoxy resin and a curing agent such as a bi- or tri-functional aromatic amine containing an electron-withdrawing group, for example, diamino diphenylsulfone and poling the mixture under high voltage at elevated temperature for a period of time to bring about orientation of the nonlinear optical moieties in the polymer. The polymers have enhanced stability over polymers in which only one end of an NLO active moiety is attached to the polymer chain.
