Multi-layer coating film with high infrared-light reflectivity and high visible-light transmissivity and forming method thereof

The present invention provides a coating composition which cures at low temperatures to form a cured film having high solvent resistance. The present invention provides a low-temperature-curable coating composition which comprises (A) a film-forming polymer having a hydrogen-donating functional group that has a heteroatom which bonds covalently to a hydrogen atom, (B) a film-forming polymer having a specific hydrogen-accepting functional group that has a heteroatom to which no hydrogen atom bonds covalently, and (C) a non-basic volatile solvent selected from the group consisting of a non-basic volatile solvent (C-1) having, in the molecule, both a heteroatom that bonds covalently to a hydrogen atom and a heteroatom that does not bond covalently to a hydrogen atom; a mixture of a non-basic volatile solvent (C-2) having, in the molecule, a heteroatom which bonds covalently to a hydrogen atom and a non-basic volatile solvent (C-3) having, in the molecule, a heteroatom to which no hydrogen atom bonds covalently; and combinations thereof.

Low-temperature-curable coating composition

It is an object of the present invention to provide a coating composition which can attain low friction performance without impairing the functions of a conventional coating composition, a coated film formed by using the same and a method of reducing friction in water. A coating composition containing an organic polymer particle, wherein said organic polymer particle has the solubility at 23&#xb0; C. in the artificial seawater specified in ASTM D1141-98 of 15 g/liter or less, the water-absorbing amount for the artificial seawater specified in ASTM D1141-98 of 0.01% by mass or more and a particle diameter of 0.05 to 100 &#x3bc;m.
