Embodiment 1

[0069] Organic substances were removed by firing S glass-based glass cloth (thickness 100 μm, refractive index 1.530, manufactured by Unitika Cloth, #2117 type), and then treated with γ-glycidoxypropyltrimethoxysilane (epoxysilane). On this glass cloth, a resin composed of 90 parts by weight of triglycidyl isocyanurate (manufactured by Nissan Chemical Industry Co., Ltd., TEPIC), bisphenol S-type ring, and 110° C. 10 parts by weight of epoxy resin (manufactured by Dainippon Ink Chemical Industry Co., Ltd., EPICLON EXA1514), 170 parts by weight of methyl hydrogenated norbornene diacid anhydride (manufactured by Shin Nippon Chemical Co., Ltd., Rikacid HNA-100), and tetraphenylphosphine bromide (North Xing Chemical Industry Co., Ltd., TPP-PB) 2 parts by weight. The glass cloth is sandwiched between the glass plates that have been released from the mold, and heated in an oven at 100°C for 2 hours, then heated at 120°C for 2 hours, at 150°C for 2 hours, and at 175°C for 2 hours to o...

Embodiment 2

[0071] A resin composed of the following compounds melt-mixed at 110° C. was impregnated on an S-glass-based glass cloth subjected to the same treatment as in Example 1, and defoamed. The above compounds are 62.5 parts by weight of triglycidyl isocyanurate (manufactured by Nissan Chemical Industry, TEPIC), 27.5 parts by weight of bisphenol S-type epoxy resin (manufactured by Dainippon Ink Chemical Industry, EPICLON EXA1514), 27.5 parts by weight of methylhexahydro-ortho 120 parts by weight of phthalic anhydride (manufactured by Shinnippon Chemical Co., Ltd., Rikacid MH-700), and 1.4 parts by weight of tetraphenylphosphine bromide (manufactured by Hokko Chemical Industries, Ltd., TPP-PB). This glass cloth was sandwiched between glass plates subjected to mold release treatment, and heat-treated in an oven under the same conditions as in Example 1 to obtain a transparent sheet with a thickness of 0.1 mm.

Embodiment 3

[0073]Organic matter was removed by burning E glass-based glass cloth (thickness 100 μm, refractive index 1.560, manufactured by Unitika Cloth, #2117 type), and then treated with γ-glycidoxypropyltrimethoxysilane (epoxysilane). A resin composed of the following compounds melt-mixed at 110° C. was dipped and defoamed on the glass cloth. The above compounds are 20 parts by weight of triglycidyl isocyanurate (manufactured by Nissan Chemical Industry, TEPIC), 80 parts by weight of bisphenol S-type epoxy resin (manufactured by Dainippon Ink Chemical Industry, EPICLON EXA1514), methyl hydrogenated 75 parts by weight of bornenedioic anhydride (manufactured by Shinnippon Chemical Co., Ltd., Rikacid HMA-100), and 1 part by weight of tetraphenylphosphine bromide (manufactured by Hokko Chemical Industry Co., Ltd., TPP-PB). This glass cloth was sandwiched between glass plates subjected to mold release treatment, and heat-treated in an oven under the same conditions as in Example 1 to obta...

Abstract

A transparent composite composition is provided which comprises an epoxy resin (a) and a glass filler (b) and in which the epoxy resin (a) comprises at least one epoxy resin whose refractive index after curing is lower than the refractive index of the glass filler (b) and at least one epoxy resin whose refractive index after curing is higher than the refractive index of the glass filler (b). The transparent composite composition of the invention has a low coefficient of linear expansion and is excellent in transparency, heat resistance and solvent resistance, among others and, therefore, is judiciously used, for example, in the form of liquid crystal display device substrates and organic EL device substrates (in particular of the active matrix type) and, further, transparent sheets, optical lenses, color filter substrates, solar cell substrates, touch panels, optical devices, optical waveguides, LED sealing materials and so forth.

Description

technical field [0001] The invention relates to a transparent composite material composition which has a small linear expansion coefficient, excellent transparency, heat resistance and solvent resistance, and can replace glass. The transparent composite material composition of the present invention, for example, can be suitably used as optical sheets such as substrates for liquid crystal display elements, substrates for organic EL display elements, substrates for color filters, substrates for touch panels, solar cell substrates, transparent plates, optical Lenses, optical components, optical waveguides, LED packaging materials, etc. Background technique [0002] In general, glass plates have been widely used as display element substrates (especially active matrix type) for liquid crystal display elements or organic EL display elements, substrates for color filters, substrates for solar cells, and the like. However, since glass plates are fragile, cannot be bent, have a larg...
