INFRARED FLUORESCENT COATINGS
The present invention provides for a composition comprising a pigment, wherein the composition is suitable for coating a surface that is, or is expected to be, exposed to the sun. The pigment comprises particles that fluoresce in sunlight, thereby remaining cooler in the sun than coatings pigmented with non-fluorescent particles. The particles comprise solids that fluoresce or glow in the visible or near infrared (NIR) spectra, or that fluoresce when doped. Suitable dopants include, but are not limited to, ions of rare earths and transition metals. A coating composition includes: (i) a film-forming resin; (ii) an infrared reflective pigment; and (iii) an infrared fluorescent pigment different from the infrared reflective pigment. When the coating composition is cured to form a coating and exposed to radiation comprising fluorescence-exciting radiation, the coating has a greater effective solar reflectance (ESR) compared to the same coating exposed to the radiation comprising fluorescence-exciting radiation except without the infrared fluorescent pigment. A multi-layer coating including the coating composition, and a substrate at least partially coated with the coating composition is also disclosed. A method of reducing temperature of an article includes applying the coating composition to at least a portion of the article.
Near infrared-reflecting/transmitting azo pigment, method for manufacturing near infrared-reflecting/transmitting azo pigment, colorant composition using said azo pigments, item-coloring method and colored item
An azo pigment is provided which can be used as a coloring agent, etc. for use in paints, plastics, synthetic fibers, printing inks, and writing materials or for image recording or image displaying and which has performance of exhibiting high near infrared reflection/transparency, particularly when used as a heat-shielding paint, even in the case where the pigment has a dark color, and as a result, colored articles having the above-described properties are provided, and furthermore an article that is also useful as a printing ink in the security field is provided particularly when the pigment has a dark or black color. Specifically, an azo pigment is provided which is obtained through coupling reaction between a particular azo component and a particular coupling component, which has a plurality of chromophores of an azomethine group and of an azo group within a molecule, and in which the diazo component is a diazotized product of 3-(4-aminophenylimino)-1-oxo-4,5,6,7-tetrachroloisoindoline.
SCREEN FOR SCREEN GOLF AND MANUFACTURING METHOD OF THE SAME
The present invention may provide a screen used for screen golf, which can improve the brightness and clarity of the image projected on the screen by suppressing the light of the image from passing through the screen and increasing the reflectance of light from the front of the screen when an image is output by a projector on the screen. In addition, despite repeated golf shots of many users, the brightness and clarity of the image projected on the screen may not be damaged.
Anti-reflective film
The present invention relates to an anti-reflective film exhibiting one or more peaks (q.sub.max) at a scattering vector of 0.0758 to 0.1256 nm.sup.−1, in a graph showing a log value of scattering intensity to a scattering vector defined in small-angle X-ray scattering.
COATING COMPOSITIONS FOR APPLICATION UTILIZING A HIGH TRANSFER EFFICIENCY APPLICATOR AND METHODS AND SYSTEMS THEREOF
A system for applying a coating composition is provided herein. The system includes a first high transfer efficiency applicator defining a first nozzle orifice and a second high transfer efficiency applicator defining a second nozzle orifice. The system further includes a reservoir. The system further includes a substrate defining a first target area and a second target area. The first high transfer efficiency applicator and the second high transfer efficiency applicator are configured to receive the coating composition from the reservoir and configured to expel the coating composition through the first nozzle orifice to the first target area of the substrate and to expel the coating composition through the second nozzle orifice to the second target area of the substrate.
Blue inorganic colourants/pigments and process for preparation thereof
Nontoxic Near infra-red Reflecting (NIR) inorganic pigments, characteristically blue and well suited for the coloration of a wide variety of substrates, for example, plastics and concrete building roofing material, etc., comprise mixed metal silicate having the general formula: La.sub.xSr.sub.1-xCu.sub.1-yLi.sub.ySi.sub.4O.sub.10, where x is equal to 0 to 0.5 and y is equal to 0 to 0.5.
