BIREFRINGENT PATTERN BUILDER AND LAMINATED STRUCTURE MATERIAL FOR PREVENTING FORGERY

摘要

PURPOSE: A birefringence pattern manufacturing material and a forgery protection laminate structure supplied in a simple manufacturing material are provided to supply the laminate structure with the birefringence pattern capable of preventing misuse of the laminated structure. CONSTITUTION: A birefringence pattern manufacturing material includes an optically anisotropic layer(12) on a support material(11). The birefringence pattern manufacturing material has an alignment layer. The birefringence pattern manufacturing material has a reflecting layer(35). The birefringence pattern manufacturing material has the reflecting layer under the supporter. The birefringence pattern manufacturing material has a bonding layer and a stripping layer. The birefringence pattern manufacturing material has a transfer bonding layer between the supporter and optically anisotropic layer.
