    摘要: The invention relates to a coating composition wherein orthoester groups block the hydroxyl groups of the poly(meth)acrylate wherein the orthoester groups can be removed through hydrolysis in order to facilitate cross-linking through reaction with isocyanate compounds. The invention also relates to a process for curing the aforementioned coating composition. The invention also relates to a process for coating substrates wherein a clear coat comprising the aforementioned coating composition is coated over a base coat. The invention also relates to a process for blocking the hydroxyl groups of a poly(meth)acrylate compound through reaction with an orthoester compound.
