Composition for reflective film, reflective film, and X-ray detector

摘要

Provided is a composition for reflective film comprising a polyvinyl acetal resin, an epoxidized vegetable oil, a solvent, a coupling agent and titanium oxide.

主权项

1. An X-ray detector comprising:
a substrate; a photoelectric conversion element which is formed on the substrate and which converts incident light to signal charges; a scintillator layer which is formed on the photoelectric conversion element and which converts incident X-ray to fluorescence; and
a reflective film which is formed on the scintillator layer using a composition for reflective film, and which reflects the fluorescence radiated from the scintillator layer, wherein the composition comprises a polyvinyl acetal resin; an epoxidized vegetable oil; a solvent; a silane coupling agent; and titanium oxide in an amount of at least 50% by weight of the total solids content, the solids content being components of the composition except the solvent.
