USE OF TITANIA PRECURSOR COMPOSITION PATTERN

A conductive metal pattern can be formed using a titania sol-gel obtained from a titania precursor composition having (a) a titanium alkoxide or titanium aryloxide, (b) a R(O).sub.mCOCH.sub.2CO(O).sub.nR' compound wherein R and R' are independently alkyl and m and n are independently 0 or 1, (c) water, (d) either an acid having a pK.sub.a less than 1 or a source of a halogen, and (e) a water-miscible organic solvent, on a substrate, wherein the molar amounts of (a) through (d) are sufficient to form a pattern of a titania sol-gel upon drying on the substrate. This pattern is contacted 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, which electroless seed metal ions are exposed to electromagnetic radiation to reduce the electroless seed metal. The article is then subjected to electroless metal plating.

FORMING CONDUCTIVE PATTERN USING TITANIA SOL-GEL 

A conductive metal pattern is formed using a layer of a titania sol-gel formed from a titania precursor composition of (a) a titanium alkoxide or titanium aryloxide, (b) R(O).sub.mCOCH.sub.2CO(O).sub.nR' wherein R and R' are independently alkyl having at least 1 carbon atom, and m and n are independently 0 or 1, (c) water, (d) either an acid having a pK.sub.a less than 1 or a source of a halogen, and (e) a water-miscible organic solvent, on a substrate, to form a layer of a titania sol-gel on the substrate. The layer is contacted with electroless seed metal ions to provide a layer of electroless seed metal ions, imagewise exposed to form non-exposed regions and exposed regions. The electroless seed metal ions in the non-exposed regions are removed and the electroless seed metal nuclei within the titania sol-gel in the exposed regions are then electrolessly plated with a conductive metal.
