Abstract

An object of the invention is to provide a fishhook for fishing or the like, the fishhook being easily stuck to a fish or the like and being also excellent in durability. The surface of a fishhook is treated with a compound selected from the group consisting of a metallic surfactant having at least one or more hydroxyl groups or hydrolyzable groups, a fluorine-based surface treating agent, a thiol compound and a disulfide compound.

First claim

The invention claimed is:

1. A fishhook subjected to a surface treatment with a compound selected from the group consisting of:
a metallic surfactant represented by formula (I):
R 1 n MX m-n   (I),

wherein:
R 1 represents a hydrocarbon group having 1 to 30 carbon atoms and optionally having a substituent, a halogenated hydrocarbon group having 1 to 30 carbon atoms and optionally having a substituent, a linking group-containing hydrocarbon group having 1 to 30 carbon atoms, or a linking group-containing halogenated hydrocarbon group having 1 to 30 carbon atoms,
M represents at least one metal atom selected from the group consisting of a silicon atom, a germanium atom, a tin atom, a titanium atom, and a zirconium atom,
X represents a hydroxyl group or a hydrolyzable group,
m represents an atomic valence of M, and
n represents any positive integer of 1 to (m-1), wherein
when n is 2 or more, each R 1 is the same or different, and
when (m-n) is 2 or more, each X is the same or different, provided that at least one of X represents a hydroxyl group or a hydrolyzable group,

a fluorine-based surface treating agent,
a thiol compound, and
a disulfide compound.

2. The fishhook according to claim 1 , wherein the fishhook is a fishhook preliminarily subjected to a surface treatment with a thin film-forming composition containing:
(a) an epoxy group-containing trialkoxysilane hydrolysis condensate;
(b) an alcohol having 1 to 5 carbon atoms, and/or an organic acid whose pKa at 25° C. is in the range of 2.0 to 6.0; and
(c) a polyamine.
