Date Jun. 26, 1997To offer thermosetting paint compositions resistant to yellowing to brass, which give paint films of excellent resistance to yellowing due to brass, low-temperature curability, weather resistance, resistance to yellowing after stoving, acid resistance, scratch resistance, solvent resistance, adhesion and appearance. Thermosetting paint compositions, which are thermosetting paint compositions which are resistant to yellowing due to brass, characterized in that the paint-film-forming components include (A) a compound which has per molecule at least 2 functional groups which can react with an isocyanate group, at 49.6-90 wt %, (B) a blocked isocyanate which has par molecule at least 2 isocyanate groups blocked by an azole blocking agent, at 9.6-50 wt %, (C) an ultraviolet absorber and / or free radical scavenger, at 0.2-5 wt %, (D) an organotin compound at 0.1-3 wt %, and (E) an amino resin at 0.1-30 wt %.
