    Patent number: 4530571
    Abstract: A mirror made of a synthetic plastics material in the shape of a shallow tray having a base which is metallized on its internal or external surface. The shallow tray has a rim integral with the periphery of the base. The shape of the cross-section of the rim enables the peripheral edge at the front of the mirror to be convexly rounded to a required radius greater than the thickness of the base. The shape of the cross-section of the rim also serves to hold the base from distortion and so maintains the optical properties of the mirror.
