    • A thermosetting composition is provided comprising: (a) a crosslinking agent having at least two functional groups that are reactive with epoxides; and (b) a non-gelled, epoxy functional polymer prepared by atom transfer radical polymerization, in the presence of an initiator having at least one radically transferable group. The polymer contains at least one of the following polymer chain structures: —{(M)p—(G)q}x— or —{(G)q—(M)p}x— wherein M is a residue, that is free of epoxy functionality, of at least one ethylenically unsaturated radically polymerizable monomer; G is a residue, that has epoxy functionality, of at least one ethylenically unsaturated radically polymerizable monomer; p and q represent average numbers of residues occurring in a block of residues in each polymer chain structure; and p, q, and x are each independently selected for each structure such that the epoxy functional polymer has a number average molecular weight of at least 250. Also provided by the present invention are methods of coating a substrate using compositions of the present invention and substrates coated by such methods, as well as color-plus-clear composite coatings.
    • 提供一种热固性组合物,其包括:(a)具有至少两个与环氧化物反应的官能团的交联剂; 和(b)在具有至少一个可自由基转移基团的引发剂的存在下通过原子转移自由基聚合制备的非胶凝的环氧官能聚合物。 聚合物含有至少一种以下聚合物链结构:或其中M是不含环氧官能团的至少一种烯属不饱和自由基聚合单体的残基; G是具有至少一个烯属不饱和自由基聚合单体的具有环氧官能度的残基; p和q表示在每个聚合物链结构的残基块中发生的残基的平均数目; 对于每种结构,p,q和x各自独立地选择,使得环氧官能聚合物的数均分子量至少为250.本发明还提供了使用本发明的组合物涂覆底物的方法和 通过这些方法涂覆的基材,以及彩色 - 透明复合涂层。
