Title:
屈折率分布型光学樹脂材料
Document Type and Number:
Japanese Patent JP4132282
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an optical resin material which is improved in heat resistance and is low in light transmittance loss by consisting this material of specific fluorine contained polymers and specific fluorine contained polycyclic compds. SOLUTION: One or more fluorine contained polycyclic compds. having a refractive index higher than 0.005 are distributed into the non-crystalline fluorine contained polymer substantially free of C-H bonds by having a concn. gradient at which the concn. decreases from the center toward the peripheral part. The fluorine contained polycyclic compds. are the fluorine contained non-condensed polycyclic compds. in which >=2 pieces of fluorine contained rings i.e., carbon rings or heterocycles having fluorine atoms or perfluoroalkyl groups are bonded by the bond including >=1 kind selected from a group of a triazine ring, oxygen atom, sulfur atom, phosphorus atom and metal atom and the C-H bonds are substantially not contained. The compds. are otherwise the fluorine contained condensed polycyclic compds. which comprise >=3 pieces of the carbon rings or heterocycles and do not substantially have the C-H bonds.
