Abstract
The present invention provides a process for producing phenol-dicarbonyl condensates high in fluorescence by reacting a phenolic compound with a 1,2-dicarbonyl compound in the presence of a catalyst selected from one or more carboxylic acid(s) or one or more carboxylic acid precursor(s). The present invention further provides phenol-dicarbonyl condensates, epoxy resins, epoxy resin systems and laminates prepared using these phenol-dicarbonyl condensates.
