Photosensitive silicone resin composition

A production process of a photosensitive silicone resin composition, comprising the following steps:

• a first step for obtaining a polysiloxane compound (a) by hydrolytically condensing one or more types of silane compounds represented by the following general formula (1):
• R1n1SiX14-n1 (1)
• (wherein, R1 represents a hydrogen atom or organic group containing 1 to 20 carbon atoms, n1 represents an integer of 0 to 3, X1 represents a group selected from the group consisting of a halogen atom, alkoxy group having 1 to 6 carbon atoms and acetoxy group having 1 to 6 carbon atoms, and n1, R1 and X1 may each be the same or different in the case a plurality thereof is present),
• a second step for obtaining a condensation reaction product by condensing the resulting polysiloxane compound (a) and/or the silane compound with silica particles (b),
• a third step for obtaining a silica particle-containing condensation reaction product (A) by condensing the resulting condensation reaction product with a silicon compound (c) represented by the following general formula (3):
• R33SiX2 (3)
• (wherein, R3 represents a hydrogen atom or organic group containing 1 to 20 carbon atoms, X2 represents a group selected from the group consisting of a hydroxyl group, halogen atom, alkoxy group having 1 to 6 carbon atoms and acetoxy group having 1 to 6 carbon atoms, and the plurality of R3 present may be the same or different), or the following general formula (4):
• R33SiNHSiR33 (4)
• (wherein, R3 is the same as defined in general formula (3)), and
• a fourth step for mixing the resulting silica particle-containing condensation reaction product (A) with a photopolymerization initiator (B).
