Abstract: Curing agents for epoxy resins are provided in which an imidazole is substituted on the nitrogen atom by a long chain group. This provides greater latexing (stability) at ambient temperatures without adversely affecting curing properties at temperatures of 50.degree. C. upwards. Those components in which the chain is substituted by a hydroxy group on the 2 position are particularly preferred and are novel compounds.
