<p>THE PRESENT INVENTION PROVIDES A PRECOATED METAL SHEET, FOR LIGHT REFLECTORS, HAVING A HIGH DIFFUSE REFLECTANCE OF VISIBLE LIGHT, AND ALSO PROVIDES THE ELECTRIC OR ELECTRONIC APPARATUS USING IT. THE PRECOATED METAL SHEET COMPRISES A METAL SHEET OR PLATED METAL SHEET (1), A VISIBLE LIGHT REFLECTIVE UNDERCOAT (2) HAVING A THICKNESS OF 3 TO 30 MICROMETERS PROVIDED ON AT LEAST ONE SURFACE OF THE METAL SHEET OR PLATED METAL SHEET (1), AND A VISIBLE LIGHT REFLECTIVE OVERCOAT (3) HAVING A THICKNESS OF 10 TO 40 MICROMETERS PROVIDED ON THE VISIBLE LIGHT REFLECTIVE UNDERCOAT (2). THE VISIBLE LIGHT REFLECTIVE UNDERCOAT (2) COMPRISES A BINDER RESIN AND A TITANIUM OXIDE, A CONTENT OF THE TITANIUM OXIDE IN THE VISIBLE LIGHT REFLECTIVE UNDERCOAT (2) BEING 40 TO 150 PARTS BY WEIGHT BASED ON 100 PARTS BY WEIGHT OF A SOLID CONTENT OF THE BINDER RESIN, AND THE VISIBLE LIGHT REFLECTIVE OVERCOAT (3) COMPRISES A FLUORORESIN-CONTAINING BINDER RESIN AND A TITANIUM OXIDE, A CONTENT OF THE TITANIUM OXIDE IN THE VICIBLE LIGHT REFLECTIVE OVERCOAT (3) BEING 40 TO 150 PARTS BY WEIGHT BASED ON 100 PARTS BY WEIGHT OF A SOLID CONTENT OF THE BINDER RESIN.</p> |
