Abstract An anti-staining additive comprising a higher unsaturated aliphatic acid ester-modified organosilicon compound that is produced by carrying out an addition reaction between(a) a higher unsaturated aliphatic acid ester that contains more than one aliphatically unsaturated bond in each molecule and(b) an organosilicon compounds that contains at least 1 silicon-bonded hydrogen atom in each moleculewith the aliphatically unsaturated bonds in component (a) present in molar excess over the silicon-bonded hydrogen in component (b). The additive can be used at 0.01 to 50 weight percent in a polyorganosiloxane composition that cures at room temperature by a condensation reaction.
