樹脂組成物の硬化物、積層体、及び樹脂組成物
Document Type and Number:
Japanese Patent JP7221843
Kind Code:
B2
Abstract:
A cured product of a resin composition according to the present invention includes at least silsesquioxane. When the average thermal expansion coefficient of the cured product at 30 to 200°C is expressed as α1 [K-1], at least one of requirements α1/α2 ≥ 10 and (α1 - α2)2 × 108 ≥ 0.4 is satisfied, where a reference value a2 is 350 × 10-6 [K-1] or less. In the cured product, an absorbance derived from a siloxane bond, an absorbance derived from a hydrocarbon group, and an absorbance derived from a hydroxy group are respectively expressed as Ia, Ib, and Ic, the absorbances being determined by attenuated total reflection using a Fourier transform infrared spectrophotometer. In this case, requirements 0.09 ≤ Ia/Ib ≤ 3.0 and 0.04 ≤ Ic/Ib ≤ 1.0 are satisfied.
