  • Patent number: 5633105
    Abstract: A conformal mask permits the manufacture of precision frequency selective surfaces (FSS) that have patterns on complexly curved surfaces. These FSSs are used in precision radomes. The mask has a transparent substrate and a patterned opaque layer on the substrate. The layer may be patterned by laser ablation. Alternatively, the patterning of the opaque layer can be accomplished by applying a layer of photosensitive material over the opaque layer and then defining temporary and permanent areas thereof. The temporary areas of the photosensitive layer and the opaque layer are removed sequentially to define the transparent portions of the mask. Parts are made by intimately mating the mask and a part body to which a layer of metal and a layer of photosensitive material have been applied, and exposing the part to radiation through the mask.

  • Patent number: 5409800
    Abstract: A photosensitive transfer material comprises a temporary substrate having provided thereon an alkali-soluble thermoplastic resin layer, an intermediate layer, and a photosensitive resin layer in this order, the interlaminar adhesion in the transfer material being the smallest at the interface between the thermoplastic resin layer and the temporary substrate. The photosensitive resin layer can be transferred to a permanent substrate without involving failure due to fine dust, air bubbles or unevenness of the permanent substrate. An image can be formed with the transfer material by adhering the transfer material to a permanent substrate at least under heat and, after stripping the temporary substrate, imagewise exposing the photosensitive resin layer to light, and processing the transferred layers to develop the photosensitive resin layer.

  • Patent number: 5376501
    Abstract: Processes are disclosed for incorporating a water-insoluble substance in a diffusion resistant form into a hydrophilic colloidal layer of an element. In a first process A the water-insoluble substance is present during the polycondensation of diol(s) or polyol(s) and carboxylic acids, whereby at least 6 mole % of the reagents bear a water-solubilizing group, preferably a sulpho group in the salt form; the obtained mixture of polyester and water-insoluble substance is then dispersed in an aqueous medium. In an alternative process B the polyester is first prepared and then mixed homogeneously with the hydrophobe substance by melting in a reactor or extruder; the mixture is then similarly dispersed. The obtained latex is then incorporated in a hydrophilic colloidal layer which is coated on a support.The obtained element can serve as base for a reprographic image, e.g. a color proof image, or can form part of a complete photographic material.
