摘要：
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.
