A curable film-forming composition is provided comprising (i) 10 to 90 percent by weight based on the total weight of resin solids in the film-forming composition of a crosslinking agent; (ii) 10 to 90 percent by weight of a polymer containing a plurality of functional groups reactive with the crosslinking agent; and (iii) 5 to 85 percent by volume of particles having a mean particle size less than 100 nm. The particles comprise 1 to 99 percent by weight of at least one metal oxide wherein the metal is selected from zinc, titanium, cerium, manganese, bismuth, copper, zirconium and iron. A multi-component composite coating composition is also provided, comprising a pigmented basecoat and a clear coat. The basecoat and/or clearcoat may be derived from the curable film-forming composition described above. Also provided are coated substrates in which the curable coating compositions or the multi-component composite coating compositions described above are applied to a substrate and cured to form a cured coating.

2504591, 250302

A method for determining the thickness of a dryable or curable film-forming coating by incorporating a fluorescent component into the coating. The fluorescent component is either a resin solid of the coating, a fluorescent dye or a fluorescent dye attached to a resin solid of the coating. The coating is exposed to ultraviolet or visible light which causes the fluorescent component to fluoresce. The intensity of the fluorescence of the coating is measured and the thickness or weight of the coating is determined from a known mathematical relationship between the fluorescence intensity of the coating when exposed to the light and the thickness or weight of the coating. Additionally, a curable or dryable film-forming coating composition including a curable or dryable organic resin reacted with a fluorescent tag is provided.

A coating composition containing a resinous binder with colorants and reflective pigments. The colorants absorb visible light at a first wavelength and produce fluorescent light at a second wavelength band when exposed to visible light. When applied to a substrate, the coating composition appears as one color on face from the specular reflection of the colorants off the reflective pigments and a different color on flop from the fluorescent light produced by the colorants.

A curable film-forming composition is provided comprising in a medium (i) 10 to 90 percent by weight based on the total weight of solids in the film-forming composition of a crosslinking agent; (ii) 10 to 90 percent by weight based on the total weight of solids in the film-forming composition of a polymer containing a plurality of functional groups reactive with the crosslinking agent; and (iii) at least 20 percent by volume based on the total volume of the film-forming composition of particles having a mean particle size less than 100 nm. A cured composition comprising the crosslinking agent of (i) and the polymer of (ii) has a cured softening point of less than 30Â C. The particles of component (iii) further have a hardness value greater than 5 on the Moh hardness scale, and have an affinity for the medium sufficient to keep the particles suspended therein. The affinity of the particles for the medium is greater than the affinity of the particles for each other, thereby preventing agglomeration of the particles within the medium. Cured compositions having a film thickness of at least 5 microns demonstrate excellent chip resistance, superior sandability and resistance to scratching, water spotting and acid etch.

A coating composition for applying to a substrate and containing a resinous binder with fluorescent colorants in an upper layer and light-absorbing particles in a lower layer. The coating composition exhibits a first color when exposed to light of a first intensity, the first color being dominated by absorbance of light by the colorants and the light-absorbing particles. When exposed to light of a higher intensity, the coating composition exhibits a second color dominated by fluorescent light emitted by the colorants.

A protective and decorative coating composition including about 2 to 10 different colorants which in combination with a resinous composition produce a desired visible coating. A majority of the colorants has a maximum haze of about 10% and exhibits an absorbance peak in the visible spectrum wherein at least about 50% of the total absorbance in the visible spectrum occurs at wavelengths within about 50 nm of the wavelength of the peak absorbance.
