The present invention can form a hard coat layer having a high surface hardness by in-mold injection molding, and is suitable as a material of a hard coat layer of a transfer film that can be formed into a tack-free coating film and wound up as a roll. It is intended to provide a polyorganosilsesquioxane. The present invention has a structural unit represented by the following formula (1), and has a molar ratio of a structural unit represented by the following formula (I) to a structural unit represented by the following formula (II) [formula (I) ) / The structural unit represented by the formula (II)] is 20 or more and 500 or less, and the structural unit represented by the following formula (1) with respect to the total amount (100 mol%) of the siloxane structural unit; The proportion of the structural unit represented by the following formula (4) is 55 to 100 mol%, the number average molecular weight is 2500 to 50,000, and the molecular weight dispersity (weight average molecular weight / number average molecular weight) is 1.0 to 4.0. A polyorganosilsesquioxane, and a curable composition containing the polyorganosilsesquioxane. Embedded image Embedded image Embedded image Embedded image |
