Title:
RESIN COMPOSITION, CURED FILM, METHOD FOR PRODUCING MICROLENS, SOLID STATE IMAGING DEVICE, MICROLENS, AND TOUCH PANEL
Document Type and Number:
WIPO Patent Application WO/2021/193221
Kind Code:
A1
Abstract:
The present invention provides a high refractive index resin composition that exhibits excellent heat resistance and dry etching properties by not containing a fused polycyclic aromatic compound and lowering the quantity of a metal compound that is difficult to etch. This resin composition contains: a polysiloxane (A) having a structure represented by formula (1); particles (B) of a composite oxide of titanium and one or more elements selected from the group consisting of aluminum, tin, zirconium and silicon; and a solvent (C). R1 denotes an alkyl group having 1-4 carbon atoms or an alkoxy group having 1-4 carbon atoms. n is 0 or 1, and ＊ denotes a direct bond to a silicon atom.
