<p>A polymer-based color changing article manufactured by injection, extrusion or similar methods that comprises transparent polymer matrix, polymeric color changing enhancer additive distributed within the polymer matrix that does not change its optical properties and a chemical compound capable of reversible changing its original color due to a photochemical reaction. The polymer-based color changing article can be used for applications such as lenses, color changing protective shields or sheets for controlling the intensity of light irradiation within a room, car, greenhouse, games, toys, memorabilia, packages for light sensitive food, beverages, and drugs.</p> |
