Title:
PRESSURE CASTING MATERIAL HAVING HOLOGRAM OR DIFFRACTION GRATING
Document Type and Number:
WIPO Patent Application WO/1991/010174
Kind Code:
A1
Abstract:
A pressure casting material having hologram or diffraction grating which is composed of a cross-linking polymer resin (2) having a relief of hologram or diffraction grating and a base material (1) made of a solid matter. This material can be obtained by bonding the cross-linking polymer resin (2) onto the surface of the solid matter (1) by pressure casting using a material having a relief of hologram or diffraction grating, and separating the material having the relief of hologram or diffraction grating from the resin layer after the resin layer is solidified. Furthermore, a metal layer (3) is formed on the pressure casting material and a protective layer (4) can be deposited thereon. Since this material has both corrosion resistance and aging resistance, it can be used suitably for the decoration of high class buildings, all industrial products and artistic handicrafts.
