摘要:
A conductive pattern is prepared in a polymeric layer that has (a) a reactive polymer comprising pendant tertiary alkyl ester groups, (b) a compound that provides an acid upon exposure to radiation having a λmax of at least 150 nm and up to and including 450 nm, and (c) a crosslinking agent. The polymeric layer is patternwise exposed to provide a polymeric layer comprising non-exposed regions and exposed regions comprising a polymer comprising carboxylic acid groups. The exposed regions are contacted with electroless seed metal ions to form a pattern of electroless seed metal ions. The pattern of electroless seed metal ions is then reduced to provide a pattern of corresponding electroless seed metal nuclei. The corresponding electroless seed metal nuclei are then electrolessly plated with a conductive metal.

Aqueous ink jet ink compositions can be used for ink jet printing colored or invisible images on receiver elements. These compositions contain a polymeric agent comprising core-shell polymeric particles. The core of the particles comprises a hydrophobic polymer having an acid number less than 10. The shell of the particles comprises a hydrophilic polymer having an acid number of at least 70. The weight ratio of the core to the shell is at least 50:50 and up to and including 90:10. Such compositions can be used in various ink jet printing systems including drop on demand and continuous ink jet printing systems.

摘要:
A conductive pattern can be formed using a polymeric layer that contains a reactive composition having a reactive polymer. This reactive polymer comprises (i) a backbone, and (ii) pendant photosensitive non-aromatic unsaturated heterocyclic groups comprising an amide group that is conjugated with a carbon-carbon double bond. The non-aromatic unsaturated heterocyclic groups are linked to the backbone at an amide nitrogen atom. The reactive composition can be patternwise exposed to suitable radiation to induce crosslinking within the reactive polymer. The reactive composition and reactive polymer in the non-exposed regions can be removed due to their aqueous solubility, but the exposed regions of the polymeric layer are contacted with electroless seed metal ions, which are then reduced, followed by electrolessly plating with a suitable metal to form the desired conductive pattern. Various articles can be prepared during this process, and the product article can be incorporated into various electronic devices.
