摘要：The present invention provides a reaction product of reactants comprising: a) a polyisocyanate; b) a hydroxyalkyl carbamate; c) an aldehyde; and d) at least one monohydric alcohol. Additionally provided is a composition of matter comprising the structure: where Q is a multi-valent organic moiety containing urethane linkages; X is H, -CH2OH, or -CH2OR'; R' is an alkyl or aryl group having from 1 to 12 carbon atoms; and y is at least 2. The reaction product described above may have the structure (i). The reaction product and composition of matter are suitable for use as crosslinking agents in a variety of curable compositions further comprising at least one polymer having functional groups that are reactive with the crosslinking agent. Such curable compositions may be used as film-forming compositions.
