    Abstract: A curable resin composition includes an acetoacetyl functional unsaturated polyester with a branched molecular skeleton containing olefinically unsaturated functional groups therein and acetoacetyl functional groups chemically bonded to the branched molecular skeleton. The acetoacetyl functional unsaturated polyester contains at least 2 wt % of the olefinically unsaturated functional groups, relative to the total weight of the acetoacetyl functional unsaturated polyester, and at least 20 wt % of the acetoacetyl functional groups, relative to the total weight of the acetoacetyl functional unsaturated polyester. The curable resin composition can be used to formulate coating compositions.
