This invention provides a thermosetting organic solvent paint comprising (A) a compound having at least two alicyclic epoxy groups in one molecule and having a number average molecular weight of less than 2000, (B) a secondary amino group-containing compound and (C) a thermolatent cationically polymerizable catalyst and further, under circumstances, (D) colloidal silica, and capable of forming a rigid coating film which is hard, tough and excellent in stain resistance, and from which pollutants, if adhered, are easily removed. This invention further provides a method to form a multi-layered top coating film which comprises applying, to a material to be coated, one or more species of colored paint and one or more species of clear paint in order, said method being characterized in that the above-mentioned paint is used as a clear paint which is to be applied on the uppermost layer.

Coating composition and method for coating therewith

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.

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.

The invention provides a non-aqueous polymer dispersion wherein a particulate polymer is dispersed in an organic solvent containing a dispersion stabilizer resin, the polymer being insoluble to the organic solvent and containing a fluoroalkyl group-containing (meth)acrylate as a monomer component. The invention further provides a curable composition comprising the non-aqueous polymer dispersion, a hydroxyl group containing resin and at least one crosslinking agent selected from the group consisting of amino resins, tris(alkoxycarbonylamino)triazines, polyisocyanate compounds and blocked polyisocyanate compounds. A highly stain-resistant coating film can be formed using the dispersion or composition of the invention.
