Abstract: An anti-fouling paint comprising a self-polishing copolymer which contains at least one side-chain bearing an organic half-ester at one terminal group exhibits an improved anti-fouling property, storage stability, and resists the cracking, peeling, and flaking problems which usually occur in paint film during long-term exposure. In particular, the use of such paint shows excellent adhesion properties on pre-coated, tin-based anti-fouling paint.

Abstract: A color electroluminescence(EL) display element and the manufacturing method thereof which can improve an RC-time delay phenomenon and the contrast of the EL display element. According to the EL display element, an auxiliary metal electrode is formed on a transparent electrode. The auxiliary metal electrode is formed by forming on the transparent electrode a metal film having a high melting point and a low resistivity, such as molybdenenum, with a thickness of about 1000 .ANG., and then by selectively etching the metal film so that it remains on the boundary between each of R, G, and B color filters with a width of about 5 to 30 .mu.m. The color filters are formed on a circular polarizing plate and sealed up with the auxiliary metal electrode, and thus the circular polarizing plate absorbs an external light incident to and reflected from a metal electrode.

Abstract: Disclosed is a thin film electroluminescent device of this invention comprising a transparent substrate, a transparent electrode, a fluorescent layer emitting a light when being charged with a certain voltage, a first and second insulating layer being laminated on the top and the bottom of the fluorescent layer to make a dopant be excited and emit a light efficiently, a first light absorbing layer being laminated on the second insulating layer to improve the function of contrast of the device of electroluminescence, a rear electrode formed on the first light absorbing layer at regular intervals, a rear insulating layer being laminated on the rear electrode to prevent the current from leaking from the rear electrode, and a second light absorbing layer being laminated on the rear insulating layer to blacken the etched portion of the first light absorbing layer. A method of fabrication is also disclosed.

Abstract: A thin-film EL display having a high-contrast ratio comprising a transparent ceramic substrate. A background electrode is formed on the lower surface of the ceramic substrate. A photochromism layer is formed on the upper surface of the ceramic substrate. The photochromism layer is black-colored when exposed to a required wavelength of light of 3,500 .ANG. to 5,100 .ANG.. Therefore, it is possible to avoid decrease in the contrast of the display device which may be caused by external light or light emitted from the fluorescent layer itself.
