    • The invention provides an improved unsaturated polyester prepared from the polycondensation of unsaturated diaeid monomers or unsaturated acid anhydride mononers and polyol monomers and. optionally, one or more saturated aliphatic or aromatic diacld monomers or anhydride monomers thereof. The improvement comprises 0.5 to 50 weight percent, based on the total monomer weight, of an hydroxyalkyl-fiinctional siloxane of formula ( 1 ) below. The invention also relates to a UV curable coating formulation containing a siloxane- functional unsaturated polyester resin, a vinyl ether functional diluents and a photoinitiator. The invention further provides a method of preparing an article with a low-surface energy coating. According to the method, at least one surface of an article with a coating formulation of the invention; and the coating is then cured as described above with UV light to form a low-surface energy coating on the surface. The invention also relates to articles having a low-surface energy coating according to the invention.
    • 本发明提供了由不饱和双酸单体或不饱和酸酐单体和多元醇单体的缩聚制备的改进的不饱和聚酯, 任选地,一种或多种饱和脂族或芳族二羧酸单体或其酸酐单体。 改进包括基于总单体重量0.5至50重量%的下式(1)的羟烷基官能化硅氧烷。 本发明还涉及含有硅氧烷官能不饱和聚酯树脂,乙烯基醚官能稀释剂和光引发剂的UV可固化涂料配制剂。 本发明还提供了制备具有低表面能涂层的制品的方法。 根据该方法,具有本发明的涂层制剂的制品的至少一个表面; 然后如上所述用UV光固化涂层以在表面上形成低表面能涂层。 本发明还涉及具有根据本发明的低表面能涂层的制品。
