Bisphenol-carboxylic acid esters are prepared from definite phenols and acetoacetic acid esters by condensing the components in the presence of hydrogen chloride at a temperature of from -10.degree. to +15.degree.C, using ethyl mercaptan as catalyst; the obtained esters are useful for stabilizing plastic resins, as varnishing resins, and as fungicidal or bactericidal agents.
