    摘要： There is described an aqueous coating composition, the aqueous coating composition comprising an acrylic polyester resin, obtainable by grafting an acrylic polymer and a polyester material, the polyester material being obtainable by polymerizing: (i) a polyacid component, with (ii) a polyol component. At least one of the polyacid component and/or the polyol component comprises a functional monomer operable to impart functionality on to the polyester resin, such that an acrylic polymer may be grafted with the polyester material via the use of said functionality. The coating composition further containing a crosslinking material, wherein the crosslinking material comprises material according to formula (I)

    wherein R1 is selected from aryl (such as C4 to C24 aryl), or aralkyl (such as C5 to C25 aralkyl);
    R2 to R5 are each independently hydrogen, alkyl (such as C1 to C20 alkyl), aryl (such as C4 to C24 aryl), aralkyl (such as C5 to C25 aralkyl) or -CHR8OR9;
    wherein R8 and R9 are each independently hydrogen, alkyl (such as C1 to C20 alkyl), aryl (such as C4 to C24 aryl), aralkyl (such as C5 to C25 aralkyl), alkoxyalkyl (such as C2 to C40 alkoxyalkyl) or an alkaryl (such as C5 to C25 alkaryl);
    wherein at least one of R2 to R5, is -CHR8OR9, suitably all of R2 to R5, are -CHR8OR9.

    摘要： A composition for fixing wound items comprising A) 0 to 90 wt % of at least one alpha, beta-unsaturated polyester and/or polyester imide resin based on at least one unsaturated mono-, di- or tricarboxylic acids and/or mono-, di- or tricarboxylic acid group containing molecules, at least one polyol and/or, in case of an unsaturated polyester imide, at least one imide having 5-membered cyclic imide moieties, B) 0.1 to 80 wt % of at least one inorganic and/or organic-inorganic hybrid component having functionalities to react with component A) and C), C) 2 to 80 wt % of at least one monomeric and/or oligomeric unsaturated component to react with component A) and B), and D) 0 to 15 wt % of customary additives, the wt % being based on the total weight of the composition. The composition provides excellent thermal transfer properties and a high level of electrical insulation properties with excellent adhesion and thermal stability.
