Abstract: The object of the present invention is to provide an optical information medium having a colored glossy effect which is single- or multi-colored in regions where a reflective layer is present, but colorless in regions where the reflective layer is absent. The optical information medium of the present invention includes a bonding part (receiving layer), at least one image part, and an adhesive layer (protective layer) covering the at least one image part, wherein each of the image part includes a micro-protrusion/depression structure including part having a micro-protrusion/depression structure on at least a part of the surface opposite to the bonding part, a reflective layer, and a mask layer, in the order from the bonding part (receiving layer), the micro-protrusion/depression structure including part is colorless or colored in one or more translucent or opaque color, and at least one of the micro-protrusion/depression structure including part of the image part is colored in one or more translucent or opaque color.

Abstract: An object of the present invention is to provide a laminated transfer medium (1) that can manufacture a printed matter or the like which includes a fine relief structure with a high non-defective rate. The laminated transfer medium can form a transfer laminate which contains a fine relief structure section having a fine relief shape onto a transfer target by using a hot stamp, and characterized in that the laminated transfer medium includes a carrier base (2), a bonding layer (3) formed on the carrier base, a fine relief structure section (4) having a fine relief shape being disposed on the bonding layer, and an adhesive layer (6) formed on the fine relief structure section, wherein the fine relief structure section is made up of separate discrete pieces positioned to be contained in area to be transferred by using the hot stamp.
