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.
