Process for producing cured coating film

摘要

There is provided a process for producing a cured coating film by crosslinking an aqueous resin containing in a molecule thereof, a group capable of being converted into an active hydrogen-containing group by the action of a proton, with a crosslinking agent reactive with active hydrogen in the active hydrogen-containing group in the presence of a crosslinking accelerator made of a water-soluble triazine compound capable of generating a proton upon reacting with water. According to the present invention, a cured coating film having a sufficient strength can be produced for a short period of time.
