    Abstract: s-Triazine compounds which can be used as sunscreen agents are prepared in a technically simpler manner by a process in which an ester of a branched alkanoic acid with a saturated aliphatic alcohol or, if appropriate, a mixture of such alcohols is used as the solvent in the reaction of a cyanuric halide with a p-aminobenzoate.
