Document Type and Number:
WIPO Patent Application WO/2016/204114
Kind Code:
A1
Abstract:
Provided is a curable composition that, by being cured, is capable of forming a cured product having an excellent ability to adhere to and remain closely adhered to a body adhered thereto. The curable composition is characterized by including a compound (A) represented by formula (X) or a polymeric stabilizer (B), and polyorganosilsesquioxane [in formula (X): r1 is an integer of 4–20; L is a group containing an epoxy group, an oxetanyl group, or a vinyl ether group; R11 and R12 are each a hydrocarbon group that may have a substituent; s1 is an integer of 1–3; t1 is an integer of 0–2 (s1+t1=3); and R13 and R14 are each a hydrogen atom or a hydrocarbon group that may have a substituent]. The polyorganosilsesquioxane has a number average molecular weight of 1000–3000 and a molecular weight distribution of 1.0–3.0, and is provided with a structural unit represented by formula (1), wherein the ratio of a structural unit represented by formula (I) to a structural unit represented by formula (II) is 5 or higher, and the ratio of the structural unit represented by formula (1) and a structural unit represented by formula (4) to the total amount of siloxane structural units is 55–100 mol%. [R1SiO3/2] (1) [RaSiO3/2] (I) [RbSiO2/2(ORc)] (II) [R1SiO2/2(ORc)] (4) [R1 is a group containing an epoxy group; Ra and Rb are each a group containing an epoxy group, a substituted or unsubstituted aryl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, or a hydrogen atom; and Rc is a hydrogen atom or a C1–4 alkyl group.]
