A display board has a substrate, a transparent photopolymerization resin layer formed on the substrate, and a picture layer formed in a surface of the transparent photopolymerization resin layer. The picture layer is composed of at least one dots-shaped colored photopolymerization resin. This display board is produced by exposing a colored photopolymerization resin film supported by a support member through a negative having a predetermined picture pattern to form a dots-shaped colored photopolymerization resin layer on the support member, transferring the dots-shaped colored photopolymerization resin layer to a surface of a transparent photopolymerization resin layer formed on a substrate to form a picture layer in the surface of the transparent photopolymerization resin layer, and setting the transparent photopolymerization resin layer in which the picture layer is formed to fix the picture layer.

Display board and method for producing the same

A peel-off developable pattern sheet comprising a transparent flexible substrate having thereon a pattern comprising a photopolymerizable color image-forming material layer and a process for producing a monochromatic or multi-color patterned display element by making use of the pattern sheet(s) are disclosed. A patterned display element can be produced in a continuous manner in an organic solvent-free working environment. The formed pattern has excellent sharpness and well-controlled surface properties.

Process for producing display element, pattern sheet therefor, and

A display such as meter panel and advertising display comprises a color image forming layer provided on a light-transmitting permanent support via a photo-polymerizable adhesive layer, and a photo-polymerizable image-receiving layer closely adhered to the color image forming layer. The display can be effectively produced by a process comprising the steps of forming a color image on a photo-polymerizable image-receiving layer of a photosensitive image-receiving material, placing it upon a photo-polymerizable adhesive layer formed on a light-transmitting permanent support to form a laminate so that the photo-polymerizable image-receiving layer and the photo-polymerizable adhesive layer face each other and then exposing the laminate to light so as to closely adhere the photo-polymerizable image-receiving layer and the photo-polymerizable adhesive layer to their adjacent layers, respectively, by the photo-polymerization. By this method, the adhesion between the photo-polymerizable image-receiving layer and the light-transmitting permanent support is improved.

Display and process for production thereof

A heat-resistant insulated electric wire and cable which comprises an electric conduction; the first coating layer thereon consists of a mixture of a binder and a finely ground and unmelted inorganic substance; and the second organic insulating coating layer formed on the first coating layer. Said heat-resistant insulated electric wire can advantageously be used for a coil of a magnet or a motor.

Process for production of heat resistant insulated electric wire and

Electrical elements for a voltage regulator are put on a printed-circuit board and disposed in an aluminum case. The electrical elements on the printed-circuit board are coated with a resilient material, with a sealing material which is composed of a resin of a low viscous and a minute granular insulating material being filled in the case, whereby the resin-sealed electrical device becomes much resistive against severe environmental changes.

Resin-sealed electrical device

Electrical elements constituting an electrical device are embedded into at least one layer of a finely divided insulating material which is formed within a case by filling the case with the insulating material. A low viscosity resin is poured into the case to be impregnated into said at least one layer of the insulating material and to form a cover layer covering the free surface of the top insulating cover layer. The resistances to moisture, vapor, shocks, vibration, cycling temperature change and so on are remarkably improved so that the highly reliable performances of the enclosed electrical device under severe environmental conditions may be ensured.
