An attachment film for an electronic display, which film is used for adjusting the optical transmissivity in a variety of electronic displays and adjusting color shades. It permits the simple and easy adjustment of the reflection of a fluorescent lamp and sunlight in and from the screen thereof and can prevent the formation of air bubbles in an adhesive layer thereof. The attachment film includes a transparent substrate and an adhesive layer which contains carbon black dispersed therein and formed on one surface of a transparent substrate.

Attachment film for electronic display device

There are provided a photosensitive resin film which can eliminate the step of development and the like, that is, can simplify the process, and in addition can form an even fluorescent substance layer in intimate contact with the surface of cells, and a back plate for PDP using the film. The photosensitive resin film comprises a substrate film and a pressure-sensitive adhesive, photosensitive resin layer provided on one side of the film, wherein the photosensitive resin layer comprises a photosensitive resin that contains a fluorescent substance and, upon exposure, causes the tackiness of exposed areas to be lowered.

Photosensitive resin film and use thereof

A lighting lamp having a display sheet laminated on the surface of a bulb thereof, said display sheet comprising a support having laminated thereon a light-susceptible layer including an active layer containing at least one of a dye and a pigment capable of coloring, fading, or discoloring by the action of an active light and an adhesive layer formed on the surface of the light-susceptible layer such that the portion corresponding to at least the display portion thereof is exposed, and being laminated on the surface of the bulb by the adhesive layer.

Lighting lamp

A lighting lamp is disclosed, comprising a lamp having laminated on the surface of a bulb thereof a display sheet, said display sheet comprising a support having thereon an active layer containing a pigment which is faded by the action of an active light and an active light-adjusting layer.
