ANISOTROPIC LIGHT DIFFUSION ADHESIVE LAMINATE, MULTILAYER SHEET, OPTICAL LAMINATE AND LIGHTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an anisotropic light diffusion adhesive layer that combinedly has an anisotropic light diffusing function and an adhesive function. SOLUTION: The anisotropic light diffusion adhesive laminate is an adhesive laminate having two or more adhesive layers containing an adhesive. At least one adhesive layer contains acicular fillers having a refractive index different from that of the adhesive, the acicular fillers are oriented nearly in the same direction and diffused. In addition, the anisotropic light diffusion adhesive laminate may be provided with two adhesive layers having a mutually different orientation of the acicular fillers. COPYRIGHT: (C)2004,JPO&NCIPI
