ABSTRACT:
An improved process is provided for attaching layers of hydrophilic, photosensitive materials onto hydrophobic plastic substrates, which comprises forming a layer of a polycrystalline, optically transparent, moisture barrier material on the substrate, followed by depositing thereon a layer of a hydrophilic, polar material, prior to depositing the photosensitive layer thereon. The process is especially suitable for the fabrication of pre-holographic elements and holograms. Holograms are fabricated by exposing and developing latent images in the photosensitive layer of pre-holographic elements and attaching to the photosensitive layer by an optical adhesive a protective cover layer comprising a plastic substrate coated with the moisture barrier material and the hydrophilic material. Additional moisture barrier protection may optionally be provided by forming a combination of moisture barrier layers and hydrophilic layers on the outer surfaces of the plastic substrates.
