LIGHT-BLOCKING COMPOSITION, LIGHT-BLOCKING FILM AND METHOD FOR PRODUCING SAME

摘要

The purpose of the present invention is to provide: a light-blocking composition which is capable of easily forming a light-blocking film that exhibits low reflectivity; a light-blocking film; and a method for producing a light-blocking film. A light-blocking composition according to the present invention contains at least (A) light-blocking particles or a light-blocking dye, and (B) a filler having a particle diameter within the range of 100-3,000 nm. The content of the filler (B) is 3-30% by mass relative to the total solid content in the light-blocking composition.
