发明名称 LIGHT-SHIELDING COATED FILM AND OPTICAL ELEMENT
摘要 <P>PROBLEM TO BE SOLVED: To provide a light-shielding coated film having both of light resistance over a long period and properties of preventing inner face reflection. <P>SOLUTION: The light-shielding coated film includes a modified silicone resin selected from an epoxy-modified silicone resin, an alkyd-modified silicone resin and an acryl-modified silicone resin and having a silicone-introduced rate of &ge;30 and &le;70%, a black inorganic pigment and inorganic fine particles having a reflection index of &ge;1.75 and &le;2.92, and is regulated so that the content of the inorganic fine particles in the light-shielding coated film may be &ge;10 and &le;40 vol.%, the surfaces of the black inorganic pigment and the inorganic fine particles may be treated with a surface-treating agent containing a silanol group, and both of the surface modified rate of the surface of the black inorganic pigment, and the surface-modified rate of the inorganic fine particles may be &ge;48%. <P>COPYRIGHT: (C)2012,JPO&INPIT
