ABSTRACT:
A method wherein a hologram is transferred from a transfer foil formed with a surface relief pattern and having a reflecting layer, and information, e.g., an image or a character, other than information originally recorded on the hologram is added to the transferred hologram. The method comprises preparing a transfer foil having a reflection relief hologram comprising a resin layer having a surface relief pattern, e.g., a relief hologram, a relief diffraction grating, etc., formed on the surface thereof, and a reflecting layer formed on the relief surface of the resin layer, transferring at least a part of the hologram to the surface of an object, and heating a part of the transferred portion with a heating device, thereby destroying the reflecting layer to record another information. Also disclosed are a method which enables a fine hologram pattern to be readily transferred to a large area, a transfer foil having a reflecting layer which enables a surface relief pattern to be transferred precisely with excellent foil breaking characteristics, and a method of producing a surface relief pattern transfer foil.
