ABSTRACT:
Disclosed is a decorative material in which a metal layer (e.g., a radio-wave-transmitting metal layer) on a non-metallic-lustrous part can be removed readily and sufficiently even when the metal layer is formed partially by a process involving an etching treatment, and can decorate a molded article with a desired pattern readily and satisfactorily. Also disclosed is a method for producing the decorative material. Further disclosed is a molded article produced by using the decorative material. Specifically disclosed is a decorative material (1) which mainly comprises: a support (2) having a first main surface (S1) and a second main surface (S2) both of which are opposed to each other; a metal oxide layer (12) which is arranged on the first main surface of the support (2) and comprises aluminum oxide; a radio-wave-transmitting metal layer (14) which is arranged on the metal oxide layer (12) and contains at least one member selected from the group consisting of Sn and In as a constituent component; a mask layer (16) which is arranged on the radio-wave-transmitting metal layer (14) and comprises a synthetic resin; and an adhesive layer (20) which is arranged on the mask layer (16) and comprises a synthetic resin. In the decorative material (1), the mask layer (16), the radio-wave-transmitting metal layer (14) and the metal oxide layer (12) are so laminated that all of these layers have almost the same pattern when observed in an almost normal direction of the main surface of the support (2).
