Claim Text:
1. A method for forming a conductive metal pattern, comprising: forming a pattern of a titania sol-gel formed from a titania precursor composition that comprises: (a) a titanium alkoxide or titanium aryloxide, (b) a R(O) contacting the pattern of titania sol-gel with electroless seed metal ions to form a pattern of electroless seed metal ions deposited within the pattern of titania sol-gel on the substrate, exposing the pattern of electroless seed metal ions to electromagnetic radiation to reduce the electroless seed metal ions, thereby forming a pattern of electroless seed metal nuclei within the pattern of titania sol-gel on the substrate, and electrolessly plating the pattern of electroless seed metal nuclei with a metal that is the same as or different from the electroless seed metal nuclei.
