    Abstract: A coating composition includes a flexible hyperbranched polyol preparable by (a) reacting a polyol comprising at least three hydroxyl groups with an aliphatic dicarboxylic acid having from 6 to 36 carbon atoms or an esterifiable derivative of the aliphatic dicarboxylic acid to form a hydroxyl-functional first intermediate product; (b) reacting the first intermediate product with a cyclic carboxylic acid anhydride to form a carboxylic acid-functional second intermediate product; and (c) reacting the second intermediate product with an epoxide-functional compound having one epoxide group to form the hyperbranched polyol. The coating composition may be cured to a coating layer having excellent flexibility.

    Abstract: A material for a surface modifying agent with which the problems of insufficient durability as abrasion and chemical resistances of surface modification effect in polyurethane surface modification by the prior surface modifying agent are resolved, and is immobilized in a matrix resin firmly and improved in durability. A reactive fluorine-containing highly branched polymer obtained by: polymerizing monomer A having in a molecule two or more radically polymerizable double bonds, monomer B having in a molecule a fluoroalkyl group and at least one radically polymerizable double bond, and monomer C having in a molecule an alcoholic hydroxy group and minimum, one radically polymerizable double bond, in presence of a polymerization initiator D in an amount of 5% to 200% by mole with respect to the number of moles of the monomer A; a curable composition containing the reactive fluorine-containing highly branched polymer; and a cured film obtained from the composition.

    Abstract: A topcoat having a polyfunctional scaffold in the form of a hyperbranched polymer (HBP) with a buoy group coupled to the HBP. The HBP can also have a “delivered” group and/or an anchor group coupled thereto. The buoy group can be a fluorinated chain end, one or more fluorinated and aliphatic chain ends and/or one or more wholly aliphatic chain ends. The “delivered” group can contain at least one of an ionic species, a fluorescent tag, a bioreactive site, a catalyst and the like, and the anchor group an epoxy, a (meth)acrylate or an isocyanate. The water-disbursable topcoat can also include a solubilizing group such as 2-butanone or 4-methyl-2-pentanone coupled to the HBP.
