Abstract
A method for forming a composite vapor-deposited film one side of which suitable for vapor-deposition on a phosphor surface of a CRT, such as a color television picture tube, has high light reflectivity, and the other side of which has a property to absorb radiant heat, and a composite vapor-deposition material suitable for vacuum deposition are disclosed. The composite vapor-deposition material has a high vapor-pressure metal envelope and a low vapor-pressure metal in the core region of the envelope. Low vapor-pressure metal powder should preferably be dispersed and held by high vapor-pressure metal powder in the core region. Vacuum deposition using this composite vapor-deposition material yields a composite deposited film having a composition comprising almost 100% of the high vapor-pressure metal formed in the initial stage of evaporation, and a composition comprising 100% of the low vapor-pressure metal formed in the final stage of evaporation.
