Abstract
This invention relates to novel water-soluble esters of oxalic acid, and to compositions that are useful for generating chemiluminescent emission by reacting said esters of oxalic acid with hydrogen peroxide in the presence of water and a fluorescent compound, and to a process for generating chemiluminescent emission by using said compositions.
