▎ 摘　　要

NOVELTY - Light-shielding ink composition comprises graphene, polyester binder resin, and ketone solvent. The polyester binder resin has glass transition temperature of 60-100 degrees C. The specific surface area of the graphene is 300-750 m2/g. USE - The composition is useful in film of optical component for optical device (all claimed). ADVANTAGE - The composition has physical properties i.e. light-shielding property, chemical resistance, and adhesion without applying carbon black or matting agent particulate component. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for light-shielding film comprising a substrate made of synthetic resin film, and a light shielding film formed on at least one surface of the both surfaces of the substrate, where the light shielding film is formed by attaching graphene to the one surface by a polyester binder resin.
