Abstract:
PURPOSE: A black photosensitive resin composition and an image display device with the same are provided to have enhanced mechanical strength and to improve applicability. CONSTITUTION: A black photosensitive resin composition contains a black organic pigment, an insulation metal oxide particle, an alkali soluble binder resin, a photopolymerication compound, a photopolymerization initiator, and a solvent. The black organic pigment further contains pigments selected among black, red, blue, green yellow, and purple.
Abstract:
PURPOSE: A black coating composition is provided to provide a black coating film which has a high resistance, heat resistance, chemical resistance and high film hardness and has durability even in high temperature process. CONSTITUTION: A black coating composition comprises: a black material, highly durable insulating metal oxide particle, a polymerizable compound and a polymerization initiator. The highly durable insulating metal oxide particle has an average particle diameter of 50 nm and a polydispersity of 2.0 or less. The highly durable insulating metal oxide is surfaced treated by a silane coupling agent. The black material comprises one or more inorganic pigment selected from carbon black, titan black, metal oxide, composite oxide, metal sulfide, and metal carbonate.
Abstract:
PURPOSE: A carbon-epoxy dielectric film using carbon/epoxy resin composition is provided to manufacture various semiconductor device such as embedded capacitor. CONSTITUTION: A carbon-expoxy dielectric resin composition contains 60-90 weight% of bisphenol-based epoxy resin, 1-30 weight% of amine hardener, 0.1-3 weight% of imidazole curing catalyst, and 1-10 weight% of carbon black. The bisphenol epoxy resin is selected from the group consisting of bisphenol type A epoxy resin, bisphenol type F epoxy resin, bisphenol type AF epoxy resin and mixture thereof.
Abstract:
