Abstract

The present invention relates to a coating composition featuring increased solids contents, which comprises at least one polyol I obtainable by subjecting at least one oligomer of the general formula I EQU R.sup.1 R.sup.2 C.dbd.[.dbd.CH--R--CH.dbd.].sub.n --CR.sup.3 R.sup.4 (I) in which R=--(--CH.sub.2 --).sub.m --, in which the index m is an integer from 2 to 6, or ##STR1## in which X=--CH.sub.2 -- or an oxygen atom PA1 R.sup.1,R.sup.2,R.sup.3 and PA1 R.sup.4 independently of one another=hydrogen atoms or alkyl; and the index n=an integer from 1 to 15; PA1 to hydroformylation and reducing the resultant aldehyde-functional products I to give the polyols I, which, if desired, are subjected to partial or complete hydrogenation.
