Provided is a metal foil laminate that: has heat resistance; has high reflectance in the visible light range; has little decrease in reflectance in environments with a high-temperature thermal load; is compatible with large surface areas; and can be used for printed circuit boards for mounting LEDs that have excellent adhesion with metals. The metal foil laminate is characterized in that: a laminate has metal foil on at least one side of a resin layer (A) containing a polyorganosiloxane and an inorganic filler; the 90&#xb0; peel strength between said resin layer (A) and said metal foil is at least 0.95 kN/m, and the mean reflectance at wavelengths of 400 to 800 nm on the surface that is exposed when the resin layer (A) is exposed by peeling and removing said metal foil is at least 80%; and the decrease in the reflectance at a wavelength of 470 nm after being treated with heat for 10 minutes at 260&#xb0; C. is not more than 5%.

Metal foil laminate, substrate for mounting LED, and light source device

An information recording-displaying card, includes: a core sheet; and an over sheet bonded to the core sheet, including: a support including an amorphous polyester resin, and a reversible thermosensitive recording layer disposed on the support, including: an electron-donating coloring compound, and an electron-accepting compound. The reversible thermosensitive recording layer is capable of relatively forming a coloring state and a decolorizing state, with a difference in at least one of heating temperature, and cooling rate after heating. The over sheet is embossable in an upper portion thereof, functions as an image displaying section, and meets the following condition (A) and condition (B): (A) (the over sheet's upper limit temperature for erasing &#x2212;30&#xb0; C.)&#x2266;(temperature of a storage elasticity E' (1.0 E+08) Pa)&#x2266;200&#xb0; C., and (B) 1.0 E+04 Pa&#x2266;(the storage elasticity E&#x2032; of the over sheet at 180&#xb0; C.)&#x2266;5.0 E+07 Pa.
