Abstract:
1. A solid-state image sensor comprising: a support; a light-receiving element formed on a first side of the support; and a light-shielding color filter formed directly on, or directly on a basecoat that is formed directly on, a second side of the support, the second side of the support being opposite to the first side of the support on which the light-receiving element is formed, wherein the light-shielding color filter is formed from a photosensitive resin composition comprising a black colorant, a photopolymerizable compound, a resin, a photopolymerization initiator and a solvent, wherein the photopolymerization initiator comprises an oxime photopolymerization initiator, and a content of the oxime photopolymerization initiator is from 6% by mass to 22% by mass with respect to a total solid content of the photosensitive resin composition, wherein the light-shielding color filter has a ratio OD wherein the oxime photopolymerization compound has a structure represented by the following Formula (2); wherein in Formula (2), R and X each independently represent a monovalent substituent, A and Y each independently represent a bivalent organic group, Ar represents an aryl group, N represents nitrogen, O represents oxygen, S represents sulfur and n is an integer of 0 to 5, wherein the bivalent organic group represented by Y has any one of the following structures in which * represents a position at which Y is bonded to an adjacent carbon atom in Formula (2):
