A method of manufacturing a transfer sheet with a color pattern having metallic luster comprising the steps of: (I) forming a mold-removing film layer on one side of a transparent or semi-transparent base film; (II) forming a semi-aqueous transparent coloring agent layer on said mold-removing film layer; (III) forming a vapor-coated aluminum layer on said transparent coloring agent layer; (IV) forming a protective film layer with an oily ink on said vapor-coated aluminum layer; (V) forming an adhesive layer with an oily paste on said oily protective film layer; and (VI) placing an original film in which the desired pattern is negative on said sensitizer layer in close contact therewith, irradiating light rays onto said original film for printing, and removing said original film; (VII) washing in water the base sheet obtained according to the steps (I) to (VI), thereby dissolving and removing unexposed portions of said aqueous sensitizer layer other than the exposed and solidified portions thereof; (IX) washing in an oily solvent said base sheet, thereby dissolving and removing portions of said oily adhesive layer and said oily protective film layer other than those portions thereof located under the exposed and solidified portions of said sensitizer layer; (X) removing the exposed and solidified portions of said sensitizer layer, and applying etching to said base sheet with the use of a suitable solvent, thereby dissolving and removing portions of said vapor-coated aluminum layer other than those portions thereof located under the remaining portions of said oily adhesive layer and said oily protective film layer.
