Abstract: A sheet-shaped matched-type electromagnetic wave absorber can obtain electromagnetic wave absorption performance with a relatively small thickness but has a problem that particularly a dimensional change in an electromagnetic wave absorption layer (resin composition layer) has a large influence on the electromagnetic wave absorption performance when being exposed to a high temperature. By laminating a resin composition layer in which a filler with an aspect ratio of 5 or more and a filler with an aspect ratio of less than 5 are dispersed and fixed with an electromagnetic wave reflection layer in a cured product of a resin composition containing an acrylic polymerizable resin and a polymerization initiator, it is possible to provide a matched-type electromagnetic wave absorber having high heat resistant dimensional stability and high electromagnetic wave absorption performance.

Abstract: A composite magnetic material has sufficient flexibility and can be produced with a high producing ability without having inferior form. The composite magnetic material contains soft magnetic metal powder and resin composition containing an A component, which is an acryl copolymer with an epoxy group, and a B component, which is phenol resin, in which the soft magnetic metal powder is dispersed in the resin composition, and a mass ratio denoted by the A component/the B component is 4 to 99. It is preferable that the mass ratio denoted by the soft magnetic metal powder/the A component+the B component) be 1 to 49.

Abstract: 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.

Abstract: An attachment film for an electronic display, which film is used for adjusting the optical transmissivity depending upon a variety of electronic displays and adjusting color shades, permits the simple and easy adjustment of the reflection of a fluorescent lamp and sun light in and from the screen thereof and can prevent the formation of air bubbles in an adhesive layer thereof.

Abstract: 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.
