Abstract
Abstract A colored plastic sheet is interposed between a pair of metallic luster plastic sheets having metallic luster pigment dispersed therein and sandwiched between a pair of transparent plastic sheets to form a metallic luster plastic card. The metallic luster plastic card has good and homogeneous luster with the use of a relatively small amount of a metallic luster pigment without entailing an increase of the total thickness of the card and also has a high optical transmission density which is required for positional recognition of the card.
