Complexes comprising at least one first polymer layer, and a second polymer layer on the first polymer layer formed on the base material, the first polymer layer and second polymer layer in the presence of a boron-containing compounds have poor interlayer adhesion. The improvement depends as containing a first polymer layer and the second first and second polymer cheungjung one or at least one boron-containing compound to both in an amount sufficient to improve the interlayer adhesion between the polymer layers. Further, there is provided an improved curable coating composition using at least one member to form a multi-layer composite coating of two or more cured coating layer formed from a thermosetting composition. Related methods and the coated substrate is also provided.
