Transfer foil having reflecting layer with surface relief pattern recorded thereon
First Claim
1. A transfer foil comprising a releasable base film, a resin layer, a reflecting layer, and a heat-sensitive adhesive layer which are stacked in the mentioned order, and having a surface relief pattern formed on the resin layer on the side thereof where the reflecting layer is provided, said transfer foil being partially heated by a thermal head from the said releasable base film so that said surface relief pattern enables transfer of a precise region, wherein:
- the peel strength (A) between said releasable base film and said resin layer is larger than the film breaking strength (B) of said resin layer, and the initial bond strength of said heat-sensitive adhesive layer is larger than said peel strength (A).

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.
