Thermally initiated reactions that occur between a polyester resin and a hexamethoxymethyl melamine crosslinker, together with the segregation phenomenon of minor components such as flow agents, have been investigated by high‐resolution XPS. High‐resolution monochromated XPS C 1s spectra can be peak‐fitted by taking into account all functionalities of the respective components of the formulation. Uncured and cured coatings based on a mixture of hexamethoxymethyl melamine and a polyester resin exhibit minor differences in terms of surface composition and in the high‐resolution C 1s peak fitting. Examination of both the elemental and chemical surface compositions clearly demonstrates that the use of flow agents in the formulation leads to their preferential segregation towards the air/film interface.
