    • A composite resin is produced by hydrolyzing and condensing a silane compound (2) containing a bissilane compound (B) represented by: XnR3-nSi—Y—SiR3-nXn  (B) wherein Y is a divalent organic group which is optionally substituted with a fluorine atom or a divalent organic group which optionally contains an aromatic ring, R is a monovalent organic group, X is OH group or a hydrolyzable group, and n is 1, 2, or 3; in the presence of (1) porous and/or hollow inorganic oxide fine particles (A); and which is an integral mixture of component (1) and component (2) which has undergone the hydrolysis and the condensation. The composite resin has voids in the resin since it contains porous and/or hollow inorganic oxide fine particles, and the composite resin can also be formed into a cured article or a cured coating with a reduced refractive index since it contains air which has the lowest refractive index.
    • 通过水解和缩合含有由下式表示的双硅烷化合物(B)的硅烷化合物(2)制备复合树脂:XnR3-nSi-Y-SiR3-nXn(B)其中Y是二价有机基团,其任选被 氟原子或任选含有芳环的二价有机基团,R为一价有机基团,X为OH基或可水解基团,n为1,2或3; 在(1)多孔和/或中空无机氧化物细颗粒(A)的存在下; 并且其是经过水解和缩合的组分(1)和组分(2)的整体混合物。 复合树脂由于含有多孔和/或中空的无机氧化物微粒而在树脂中具有空隙,并且复合树脂也可以形成为具有折射率降低的固化物或固化涂层,因为它含有最低的空气 折射率。

    • A photocurable and thermosetting coating composition which is solventless and liquid at room temperature is provided. This coating composition provides scratch resistance, crack resistance, smudge resistance, and removability of oil-base felted markers by wiping with the underlying substrate, and this coating composition contains a silicone resin represented by: (R1R2R3SiO1/2)a(R4R5SiO2/2)b(R6SiO3/2)c(SiO4/2)d(O1/2X)e   (1) wherein X is hydrogen atom or an alkyl group; R1 to R6 are respectively at least one monovalent organic group which is a monovalent aliphatic hydrocarbon group or a monovalent aromatic hydrocarbon group optionally substituted with a substituent such as a poly(hexafluoropropylene oxide) structure-containing group; a, b, d, and e are 0 or a positive number; c is a positive number; and a+b+c+d is 1. The silicone resin contains at least one group represented by: CH2═C(R7)COOCH2—   (2) wherein R7 is hydrogen atom or methyl group.
