Highly concentrated, storage stable aqueous dispersions of a light stabiliser or of a mixture of a light stabiliser with an antioxidant contain more than 47 % by weight active substance, at least one non-ionic crosslinking agent as dispersing agent and a polyglycol as solubiliser, as well as 0.2 to 5 % by weight oleic acid as fluidising agent. Other components may be anionic crosslinking agents and biocides. The claimed dispersions can be easily incorporated into coating masses, such as an aqueous dispersion, an aqueous emulsion or an aqueous solution of a binder based on crosslinkable alkyd resin, acrylic resin, polyester resin or polyurethane resin.
