Title:
LIGHT REFLECTING FILM, LIGHT REFLECTING LAMINATED BODY, AND LIGHT REFLECTING CIRCUIT BOARD
Document Type and Number:
WIPO Patent Application WO/2011/118449
Kind Code:
A1
Abstract:
Disclosed are a light reflecting film which exhibits excellent light reflecting properties and which is ideal for use as a circuit board, and a light reflecting circuit board and a light reflecting laminated body which use the film. The light reflecting laminated body is formed from at least a light reflecting film, and a circuit board layer or a conductive layer bonded via an adhesive layer to at least one surface of the light reflecting film. The light reflecting film is formed from a thermoplastic liquid crystal polymer film wherein a crystal domain is present in an amorphous matrix; the crystal domain being present at a rate of 8-40 parts for each 10μm in the thickness direction of the film. The light reflecting film can have a light reflection rate of 60% or more for a wavelength of 470nm.
