GAS BARRIER FILM HAVING EXCELLENT WEATHER RESISTANCE |
摘要 |
Provided is a weather-resistant gas barrier film capable of keeping a high delamination strength and an excellent gas barrier property in a high-temperature high-humidity environment and in a UV radiation environment. The gas barrier film comprises a substrate film, a weather-resistant coating layer formed on at least one surface thereof, and an inorganic thin film layer formed on the surface of the coating layer, wherein the weather-resistant coating layer is selected from (1) a weather-resistant coating layer that contains an acrylic copolymer having at least one group selected from a UV-stabilizing group, a UV-absorbing group and a cycloalkyl group, (2) a weather-resistant coating layer formed by crosslinking a polycaprolactone-polyol and/or a polycarbonate-polyol as the essential ingredient, and (3) a weather-resistant coating layer formed by crosslinking a modified polyvinyl alcohol; and also provided is a method for producing the gas barrier film. |
