Title:
FLUORINATED POLYAMIC ACID RESIN COMPOSITION FOR OPTICAL MATERIAL
Document Type and Number:
Japanese Patent JP2007084794
Kind Code:
A
Abstract:
To find a compound capable of reducing a light absorption at 1.49 μm and a light absorption extending from 1.35 μm to visible light, even if the baking temperature is ≤340°C and to provide a fluorinated polyamic acid resin composition for optical materials containing the compound.
A fluorinated polyamic acid resin composition for optical materials contains a fluorinated polyamic acid and a non-polycondensable compound (A) with an aromatic ring having a boiling point of ≤340°C, and the resin composition is used for obtaining a fluorinated polyimide membrane by a baking process.
