Abstract
Articles for recording a holographic image are described. The articles include a holographic recording medium having a plurality of surfaces, having a transparent polymeric binder and a photochemically active dye, the holographic recording medium having a holographic image recorded therein formed by exposed areas of the photochemically active dye and unexposed areas of the photochemically active dye; and a first light-blocking layer or material over a first surface of the holographic recording medium from which surface the holographic image is viewed, the light blocking layer or material absorbing light in the wavelength range to which the photochemically active dye is sensitive and allowing transmission of light in a different wavelength range for viewing the holographic image.
