Organosiloxane resin composition and laminate comprising the same

An organosiloxane resin composition comprising:

• (A) colloidal silica (component A);
• (B) a hydrolyzed and condensed product of an alkoxysilane represented by the following formula (B) (component B):
• R1mR2nSi(OR3)4-m-n (B)
• (wherein R1 and R2 are each independently an alkyl group having 1 to 4 carbon atoms or vinyl group, all of which may be substituted by at least one group selected from the group consisting of methacryloxy group, amino group, glycidoxy group and 3,4-epoxycyclohexyl group, R3 is an alkyl group having 1 to 4 carbon atoms, m and n are each independently an integer of 0, 1 or 2, and (m+n) is an integer of 0, 1 or 2);
• (C) a hydrolyzed and condensed product of an alkoxysilane represented by the following formula (C) (component C):
• R4jR5kSi(OR6)4-j-k (C)
• (wherein R4 is an aromatic group having 6 to 12 carbon atoms which may be substituted, alicyclic hydrocarbon group having 3 to 12 carbon atoms which may be substituted, or alkyl group having 1 to 20 carbon atoms which is substituted by a fluorine atom, R5 is an alkyl group having 1 to 4 carbon atoms or vinyl group, all of which may be substituted by at least one group selected from the group consisting of methacryloxy group, amino group, glycidoxy group and 3,4-epoxycyclohexyl group, R6 is an alkyl group having 1 to 4 carbon atoms, j is an integer of 1, 2 or 3, k is an integer of 0, 1 or 2, and (j+k) is an integer of 1, 2 or 3.);
• and
• (D) a metal oxide (component D), wherein
• the content of the component A is 10 to 59.9 wt % in terms of SiO2, the content of the component B is 40 to 89.9 wt % in terms of R1mR2nSiO(4-m-n)/2, and the content of the component C is 0.1 to 18 wt % in terms of R4jR5kSiO(4-j-k)/2 based on 100 wt % of the total of the components A to C, and the content of the component D is 0.1 to 15 parts by weight based on 100 parts by weight of the total of the components A to C.
