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.

A display board has a light transmitting substrate illuminated by a light source at the back side, a illuminance adjusting layer having a plurality of light reflective dots and formed on the surface at the front side of the substrate, and a colored light transmitting image layer formed on the illuminance adjusting layer. This display board is manufactured by forming a illuminance adjusting layer and image layer sequentially on the same side of the substrate.

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

The present invention relates to an insulating coating material for an electronic circuit board, an insulating coating layer for an electronic circuit board, and a method for forming such insulating coating layer, and the insulating coating material is a solution comprising a thermoplastic resin and a solvent containing a low boiling solvent, which solution can be prevented from dropping after its application onto the electronic circuit board, and the insulating coating layer is formed using the coating material on the surface of the electronic circuit board having edge portions thereon so that the coating thickness at the edge portions and that at the other portion than the edge portions are almost equal to each other, further, the method for forming such insulating coating layer is characterized by forming the coating layer using the above insulating coating material according to a spray method or a dipping method.

Method for forming insulating coating material for electronic circuit

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.
