Title:
OPEN TYPE POROUS REFLECTOR
Document Type and Number:
Japanese Patent JP2003004921
Kind Code:
A
Abstract:
To provide an open type porous reflector containing no pigment or metal and having excellent diffusion reflectance which can be easily manufactured with relatively low energy.
A open type porous reflector is obtained by uniformly mixing a solvent-free thermosetting resin (A), the hardening agent (C) for the resin and polyalkylene oxides or polyalkylene glycols (B) compatible with the solvent- free thermosetting resin, hardening the mixture and eluting the component (B) with a solvent (D) from the molded product. The obtained reflector has ≥75% diffuse reflectance in the region from 380 nm to 2500 nm.
