Patent number: 8388870Abstract: Provided are a composite of nanoparticles of a metal such as gold, silver, a platinum metal, or copper, and a polymer, the composite allowing formation of a metal film having a sufficiently low resistivity in terms of practicality simply by drying at room temperature without requiring any special heating-baking step or any step of removing a protective agent with a solvent; a dispersion liquid of the composite; methods for producing the foregoing; and a plastic substrate formed from the dispersion liquid. The composite comprises a (meth)acrylic-based copolymer having, as side chains, a polyethylene glycol chain and a phosphate residue represented by —OP(O)(OH)2 and having, at at least one end of the molecular chain, —SR (where R represents an alkyl group or the like).Type: GrantFiled: September 6, 2010Date of Patent: March 5, 2013Assignee: DIC CorporationInventors: Yoshiyuki Sano, Nobuhiro Sekine, Ren-Hua Jin, Hiroshi Yonehara, Masafumi Uota
