Abstract (en)
A light-transmitting material which is used as an outer surface member of a device having a light source therein and which is illuminated with light from the light source when turned on comprises a light-transmitting layer which transmits light and which is lightly tinted, and a light-shielding layer provided on or adjacent the reverse surface of the light-transmitting layer. The light-shielding layer is composed of a light-shielding portion which transmits substantially no light and a light-transmitting portion which is defined by minute apertures, slits or the like provided at a predetermined density. Accordingly, when the light source is not turned on, the exterior of the light-transmitting material appears to be a composite color which is composed of the color of the light-shielding portion and the color of the light-transmitting layer.
