Claims11
A method of treating the surface of a frame of spectacles which comprises coating a surface treating composition comprising a metal complex on part or the whole of the surface of the frame of spectacles and then subjecting the frame of spectacles to a heat treatment wherein the heat treatment is carried out by heating and maintaining the frame of spectacles at 100-250° C. and then further heating and maintaining it at 280-450° C.
A method of treating the surface of a frame of spectacles which comprises coating a surface treating composition comprising a metal complex on part or the whole of the surface of the frame of spectacles and then subjecting the frame of spectacles to a heat treatment not exceeding 450° C., wherein, for the heat treatment, the frame of spectacles coated with the surface treating composition is set on a mesh-type jig.
A method of treating the surface of a frame of spectacles which comprises coating a surface treating composition comprising a metal complex on part or the whole of the surface of the frame of spectacles and then subjecting the frame of spectacles to a heat treatment not exceeding 450° C., wherein two or more species of the metal complex are used for color modulation.
A method of treating the surface of a frame of spectacles which comprises coating a surface treating composition comprising a metal complex on part or the whole of the surface of the frame of spectacles and then subjecting the frame of spectacles to a heat treatment not exceeding 450° C., wherein at least one gold complex and at least one metal complex of a metal selected from the group consisting of cobalt, copper, zinc, ruthenium, rhodium, palladium, manganese, silver, tin, platinum, iridium and bismuth are used as the metal complex.
