Patent ID: 8530559

Claim:
A composite of an organic compound and copper nanoparticles, the composite comprising a thioether-containing organic compound (A) represented by a general formula (1) below and copper nanoparticles (B) X—(OCH 2 CHR 1 ) n —O—CH 2 —CH(OH)—CH 2 —S—Z (1) [in the formula (1), X represents a C 1 to C 8 alkyl group; R 1 represents a hydrogen atom or a methyl group; n represents a repeating number, an integer of 2 to 100; R 1 is independent between repeating units and may be the same or different; and Z represents a C 2 to C 12 alkyl group, an allyl group, an aryl group, an arylalkyl group, —R 2 —OH, —R 2 —NHR 3 , or —R 2 —(COR 4 ) m (where R 2 represents a C 1 to C 4 saturated hydrocarbon group; R 3 represents a hydrogen atom, a C 2 to C 4 acyl group, a C 2 to C 4 alkoxycarbonyl group, or a benzyloxycarbonyl group that may optionally have, as a substituent on the aromatic ring, a C 1 to C 4 alkyl group or a C 1 to C 8 alkoxy group; R 4 represents a hydroxy group, a C 1 to C 4 alkyl group, or a C 1 to C 8 alkoxy group; and m represents 1 to 3)].
