  A process for preparing an aldol ester of the formula (I), wherein at least one carboxylic anhydride of the formula (II) is reacted with at least one aldol of the formula (III) with heating in the presence of a basic catalyst with a pKa of the conjugate acid of at least 8, and the reaction product obtained from the process. The process provides a light-coloured and low-odour reaction product which has a high content of aldol ester content of the formula (I) and can be used, without elaborate purification steps, particularly without overhead distillation of the aldol ester, as a blocking agent for primary amines. The resultant blocked amines have a long storage life together with polymers containing isocyanate groups, and cure rapidly and reliably on contact with moisture to form mechanically high-grade and robust elastomers.
