    摘要： Provided is a silicone resin composition useful for production of a cured product of a silicone resin composition having high UV stability.
    A silicone resin composition comprising at least one silicone resin, satisfying the following requirements (i) to (iii) :
    (i) silicon atoms contained therein essentially consist of at least one kind of silicon atoms selected from the group consisting of A1 silicon atoms and A2 silicon atoms, and A3 silicon atoms, and a ratio of the content of the A3 silicon atoms to the total content of the A1 silicon atoms, the A2 silicon atoms and the A3 silicon atoms is 50 mol% or more and 99 mol% or less;
    (ii) side chains bonding to the silicon atoms are alkyl groups having 1 to 3 carbons, alkoxy groups having 1 or 2 carbons or hydroxyl groups, a molar ratio of the alkoxy groups is less than 5 to 100 of the alkyl groups, and a molar ratio of the hydroxyl groups is 10 or more to 100 of the alkyl groups; and
    (iii) a metallic catalyst is not substantially contained.
