It is to provide a silsesquioxane having ±,²-diol group, and to provide an organic-inorganic hybrid resin composition comprising silsesquioxane and hydroxyalkyl cellulose. A composition comprising a cage-type structure of silsesquioxane represented by general formula (A), and a partially cleaved cage-type structure of silsesquioxane represented by general formula (B);
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ(RSiO 3/2 ) 1 €ƒ€ƒ€ƒ€ƒ€ƒ(A)
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ(RSiO 3/2 ) m (RSiO 2 H) n €ƒ€ƒ€ƒ€ƒ€ƒ(B)
[wherein in formulae (A) and (B), 1 and m represent an integer of 4 or more, n represents an integer of 1 or more, and n/(1 + m) is 0.03 to 0.2; each R may be the same or different, and represents an alkoxy group with 1 to 10 carbons, etc.; wherein at least one R in one molecule is a group having ±,²-diol group, and when the number of groups having ±,²-diol is 2 or more, they may be the same or different]. |
