<P>PROBLEM TO BE SOLVED: To provide a metal foil laminate having high heat resistance, high reflectance in a visible light region and small decrease in reflectance under a high temperature heat load environment, while being compatible to large area increase, excellent in metal adhesive property and usable for a printed circuit board for mounting an LED. <P>SOLUTION: A metal foil laminate is a laminate comprising a metal foil at least on one side of a resin layer (A) containing polyorganosiloxane and inorganic filler. In the metal foil laminate, 90 degrees peel strength between the resin layer (A) and the metal foil is equal to or more than 0.95 kN/m, average reflectance at wavelength 400-800 nm is equal to or more than 80% on an exposed surface when the metal foil is peeled off to expose the resin layer (A), and a reduction rate of reflectance at wavelength 470 nm is equal to or less than 5% after a heat treatment in 260°C for 10 minutes. <P>COPYRIGHT: (C)2012,JPO&INPIT |
