Claim Text:
1. A method for preparing silver nanoparticles comprising reduction treatment of a silver-containing composition comprising: silver compound (A) represented by formula (1): amine compound (B) having a primary amino group; and polymer (C) obtained by polymerization of a monomer composition comprising diol (meth)acrylate compound (c1) having a urethane bond represented by formula (2): wherein R 1 is a hydrogen atom or a methyl group, R 2 is —(CH 2 ) n —, and n is an integer of 1 to 4 , and at least one monomer (c2) selected from (meth)acrylate monomers, acrylamide monomers, vinyl monomers, vinyl ether monomers, or monomers having an epoxy group; wherein a content of said amine compound (B) is 1 to 50 mole equivalent of silver elements in said silver compound (A), and a content of said polymer (C) is 0.1 to 0.9 parts by mass with respect to 100 parts by mass of silver elements in said silver compound (A).
