Abstract: A coating composition comprises a film forming component including resin and 0.05 to 20% by weight, based on 100% by weight of the film forming component, of at least one hydroxide selected from among calcium hydroxide, aluminum hydroxide, magnesium hydroxide and zinc hydroxide. The coating composition gives excellent resistance to filiform corrosion to an article under high humidity and under a long term exposure.

Abstract: An ultraviolet-absorbing amino compound; a paint containing the aforesaid ultraviolet-absorbing amino compound; and a coated article having on its surface a coated film containing the aforesaid ultraviolet-absorbing amino compound are provided. The ultraviolet-absorbing amino compound is produced by reacting (a) a compound having a light absorption maximum within a wavelength region of 300 to 400 m.mu. and containing a mono-, di- or tetra-hydroxyphenyl group, (b) at least one compound containing a amino group and (c) formaldehyde, in the presence of at least one alcohol. The ultraviolet-absorbing amino compound of this invention is used in resin products which undergo photodegradation by ultraviolet light, for example, paints or molded articles of resins, and is especially effective for use in thermosetting synthetic resin paints.

Abstract: A pre-coated metal sheet is prepared by coating a metal sheet with an acrylic resin comprising a dispersion of a granular rubbery material in an acrylic-based resin matrix which acrylic-based resin matrix contains monomer units having functional groups which cross-link upon heating.
