Abstract
A process for preparing a reflexible pigment consisting of a metal deposition layer and resinous coating layer on at least one side thereof and having a length and width of 0.1 to 500 .mu., a thickness of 0.1 to 4 .mu. and a true specific gravity of 1 to 2, which is characterized by providing on a base film a metal leaf consisting of a metal deposition layer and a resinous coating layer on at least one side thereof, peeling the metal leaf out of the base film by elongating the base film and crushing up the metal leaf. According to the process, a reflexible pigment in a dry state can be prepared with a remarkable simplicity and a high efficiency. The coating composition including the pigment prepared by the process has improved properties such as beautifulness, reflection property, application property, weather-proofing and abrasion resistance, and is useful for printing ink, writing ink or paint.
