Abstract: A chemical indicator or ink, and methods for manufacture thereof, comprises at least one carbon dioxide-sensitive reactive dye which is capable of detecting changes in carbon dioxide concentration in a fluid under fluid and/or gas phase pressure of carbon dioxide above approximately (1) bar. The present chemical indicators or inks are useful in the monitoring of relatively high carbon dioxide pressure environments, such as in carbonated drinks. The present invention also relates to containers for holding a carbonated liquid, and closures therefore, comprising a carbon dioxide indicator or a carbon dioxide-sensitive ink, wherein the carbon dioxide indicator and/or the ink comprises at least one carbon dioxide-sensitive reactive dye which is capable of detecting changes in carbon dioxide concentration in a fluid under fluid and/or gas phase pressure of carbon dioxide above approximately (1) bar.

Abstract: A chemical indicator comprises a particulate inorganic substrate, and at least one reactive dye or ink coated on and/or impregnated within the particulate inorganic substrate. Coating and/or impregnating at least one reactive dye or ink on or within a particulate inorganic substrate improves the storage stability and/or thermal stability of the at least one reactive dye or ink, which typically comprises relatively unstable compounds. This allows the present indicators to be incorporated into thermoplastic polymer materials and processed conventionally while maintaining the efficacy and stability of the new indicators. The indicators provide simple, reliable, and cost effective detection means for detecting analytes such as ammonia, carbon dioxide, and oxygen, and may find use in applications such as food packaging and medical applications.

Abstract translation: 化学指示剂包括无机颗粒颗粒和至少一种涂覆在颗粒状无机基材上和/或浸渍于无机颗粒颗粒内的活性染料或油墨。 在颗粒状无机基材上或其内部涂覆和/或浸渍至少一种活性染料或油墨改善了至少一种活性染料或油墨的储存稳定性和/或热稳定性，其通常包含相对不稳定的化合物。 这允许将本指标并入热塑性聚合物材料中并且在保持新指标的功效和稳定性的同时进行常规加工。 这些指标提供简单，可靠和经济有效的检测手段，用于检测氨，二氧化碳和氧气等分析物，并可用于食品包装和医疗应用等应用。
