Abstract:
A resin film, obtained by forming a composition comprising:(I) a cyclic olefin addition copolymer which comprises a repeating unit (a) shown by the following formula (1), wherein A1 to A4 individually represent a hydrogen atom, a hydrocarbon group having 1-20 carbon atoms, or an alkoxysilyl group or an aryloxysilyl group shown by (CR1R2)fSi(OR3)gR4(3-g), â€”(CR1R2)fSi(R3R4)OSi(OR3)gR4(3-g), or â€”(CR1R2)fC(O)O(CH2)hSi(OR3)gR4(3-g), &Parenopenst;wherein R1 and R2 individually represent a hydrogen atom or a hydrocarbon group having 1-20 carbon atoms, R3 represents an alkyl group, alkenyl group, aryl group, or cycloalkyl group, each having 1-10 carbon atoms, R4 is a hydrogen atom, a halogen atom, or a hydrocarbon group having 1-20 carbon atoms, f and h are integers of 0-5, and g is an integer of 1-3&Parenclosest;, provided that at least one of A1 to A4 represents the alkoxysilyl group or aryloxysilyl group, Y represents â€”CH2â€” or â€”Oâ€”, and m is either 0 or 1, and a repeating unit (b) shown by the following formula (2), wherein B1 to B4 individually represent a hydrogen atom, an alkyl group, aryl group, alkenyl group, or cycloalkyl group, each having 1-20 carbon atoms, a halogen atom, a halogenated hydrocarbon group, or a polar group shown by â€”(CH2)jX, &Parenopenst;wherein X represents â€”C(O)OR5 or â€”OC(O)R6, &Parenopenst;wherein R5 and R6 represent an alkyl group, alkenyl group, aryl group, cycloalkyl group, each having 1-20 carbon atoms, or a halogen-substituted group of these groups&Parenclosest;, and j is an integer of 0-5&Parenclosest;, B1 and B2 or B3 and B4 may form an alkylidenyl group, B1 and B4, B1 and B3, or B2 and B4 may form a cycloalkylene group or a cycloalkenylene group, and n is an integer of 0-2, wherein the composition further comprises at least one of, (II) at least one compound selected from the group consisting of an organosilane shown by the following formula (3), a hydrolyzate of the organosilane, and a condensation product of the organosilane, (R7)pSi(OR8)4-pâ€ƒâ€ƒ(3) wherein R7 individually represents an organic group having 1-10 carbon atoms, R8 individually represents an alkyl group having 1-5 carbon atoms or an acyl group having 1-6 carbon atoms, and p is an integer of 0-2; and (III) at least one metal oxide selected from the group consisting of silica, alumina, zirconia, and titania.
