The present invention provides a thermosetting organic solvent type coating capable of forming a cured coating film having a TUKON hardness at 20&deg; C. of 15 or more and the minimum value of dynamic modulus E&prime; at a frequency of 110 Hz in the temperature range of 150-200&deg; C., of 1&times;10,dyn/cm or more. The cured film formed from the coating, as compared with the cured films formed from conventional organic solvent type coatings used as a top coat for automobile (e.g. an organic solvent type coating containing, as main components, a hydroxyl group-containing acrylic resin and a melamine resin, or a carboxylic-epoxy type coating), is at least equivalent in weatherabiIity, finish appearance, acid resistance, etc. and superior in stain resistance.

Coating composition and method for application thereof

The present invention provides a thermosetting organic solvent type coating capable of forming a cured coating film having a TUKON hardness at 20&deg; C. of 15 or more and the minimum value of dynamic modulus E&prime; at a frequency of 110 Hz in the temperature range of 150-200&deg; C., of 1&times;10,dyn/cm,or more. The cured film formed from the coating, as compared with the cured films formed from conventional organic solvent type coatings used as a top coat for automobile (e.g. an organic solvent type coating containing, as main components, a hydroxyl group-containing acrylic resin and a melamine resin, or a carboxylic-epoxy type coating), is at least equivalent in weatherability, finish appearance, acid resistance, etc. and superior in stain resistance.

The present invention provides a thermosetting organic solvent type coating capable of forming a cured coating film having a TUKON hardness at 20.degree. C. of 15 or more and the minimum value of dynamic modulus E' at a frequency of 110 Hz in the temperature range of 150-200.degree. C., of 1.times.1O.sup.9 dyn/cm.sup.2 or more. The cured film formed from the coating, as compared with the cured films formed from conventional organic solvent type coatings used as a top coat for automobile (e.g. an organic solvent type coating containing, as main components, a hydroxyl group-containing acrylic resin and a melamine resin, or a carboxylic-epoxy type coating), is at least equivalent in weatherability, finish appearance, acid resistance, etc. and superior in stain resistance.
