摘要:
A carbon black graft polymer that is prepared by mixing a block or graft polymer comprising a segment (A) having groups reactive with the functional groups present on the surface of carbon black and a segment (B) having a skeletal structure different from that of the segment (A) with carbon black under heating and is excellent in the dispersibility in various media, pigmentation and light screening properties. A graft polymer produced by further incorporating an ethylenically unsaturatred double bond and/or a carbonyl group into the graft chain of the above graft polymer exhibits also photosensitivity, alkali developability, insulating characteristics or the like, thus being useful as a black photo-curable resin composition suitable for forming the black matrix of a color filter.

摘要:
A process for the production of a liquid crystal display device having a color filter comprises assembling comprising, in order, afirst support member, a plurality of first electrodes secured to the first support member, a liquid crystal layer, at least one second electrode and a second, substantially transparent support member. An imageable layer which, upon exposure to actinic radiation, can form three different colors, is disposed between the first and second support members, and the assembly is exposed to actinic radiation so as to produce in the imageable layer a plurality of filter elements of first, second and third colors, these filter elements being aligned with the first electrodes, thereby forming the color filter in situ between the first and second support members.
摘要:
A carbon black graft polymer which excels in stability of dispersion in various media, coloring property, and imperviousness to light is obtained by mixing under heating a block- or graft-copolymer having a segment (A) containing a reactive group capable of reacting with a functional group on the surface of carbon black and a segment (B) different in skeletal structure from the segment (A) with carbon black. The carbon black graft polymer, by causing the graft chain thereof to incorporate therein an ethylenically unsaturated double bond and/or a carboxyl group, is enabled to manifest photosensitivity, developability with an alkali, and insulating property and acquire usefulness for a black photocurable resin composition such as, for example, the material for the formation of a black matrix particularly in a color filter.
摘要:
A method is provided for manufacturing a multicolour filter array element, firmly associated with a transparent electrode layer in a multicolour liquid crystal display device, comprising a silver halide colour photographic material wherein the colour processing of the silver halide colour material comprises a treatment of the colour processed colour material in a solution comprising at least one group III metal ion. The processing method diminishes the yellowing, due to heating, of the processed photographic silver halide colour material.
摘要:
A light-sensitive material for a color filter (2) is described, which comprises a support having provided thereon a peeling layer and further provided thereon at least three silver halide emulsion layers which are different in color sensitivity. A process for producing a color filter is also described, which comprises the steps of adhering an emulsion side of the light-sensitive material to a light-transmitting substrate, peeling the support off the light-sensitive material, pattern-exposing the emulsion side, and subjecting the material to development processing and desilvering processing.
摘要:
Le filtre transmissif, utilisable dans un écran plat de visualisation, comprend un substrat transparent (14) portant sur une face une mosaïque de pixels colorés constituée par des émulsions photographiques au moins trichromes. La densité des émulsions est variable suivant l'emplacement à la surface du substrat, de façon à compenser les variations spatiales d'éclairement d'une source d'illumination (28-32).
