  • Coating composition and its use and process for its preparation
    Patent number: 6274660
    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 R1R2C═[═CH—R—CH═]n—CR3R4  (I) in which R=—(—CH2—)m—, in which the index m is an integer from 2 to 6, or in which X=—CH2— or an oxygen atom R1,R2,R3 and R4 independently of one another=hydrogen atoms or alkyl; and the index n=an integer from 1 to 15; 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.
