Title:
LOW DIELECTRIC CONSTANT INSULATING COATING COMPOSITION, CURED PRODUCT OF SAME AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/032724
Kind Code:
A1
Abstract:
The present invention provides a low dielectric constant insulating coating composition, a cured product of which has a low relative dielectric constant and a low dielectric loss tangent, and which exhibits excellent workability when applied to a substrate. The present invention provides a low dielectric constant insulating coating composition that contains: (A) an addition reaction product of (a) a compound which is represented by formula (1) and has two hydrogen atoms in each molecule, each of the hydrogen atoms being bonded to a silicon atom, and (b) a polycyclic hydrocarbon which has two addition reactive carbon-carbon double bonds in each molecule; (B) a compound which has three or more hydrogen atoms in each molecule, each of the hydrogen atoms being bonded to a silicon atom; and (C) a hydrosilylation catalyst. (In formula (1), R independently represents an unsubstituted or substituted monovalent hydrocarbon group having 1 to 12 carbon atoms, or an alkoxy group having 1 to 6 carbon atoms.)
