摘要:
The present invention is directed, at least in part, to methods for imagewise patterning of a surface. Such patterned surfaces can be used, e.g., in microfluidic devices. Accordingly, the present invention is also directed, at least in part, to nanopatterned devices which include a microchannel structure and methods for forming such devices.
摘要:
Non-conductive real images are formed on substrates by depositing reducible metal salt compositions thereon and exposing the coated substrates to radiant energy or a chemical reducing agent to reduce the metal salt to metallic nuclei and to produce a real image of metal, which is made clearer and built up by electroless metal deposition. The metal salt composition can either be selectively deposited and then exposed, or uniformly deposited and then selectively exposed, to produce the real image.

摘要:
A non-reversal imaging process wherein a recording element having a layer of a photosensitive composition which upon light exposure produces light-generated nuclei of a metal more noble than silver, i.e. Pd, Pt, Au, is exposed to an image. The exposed element is treated with a solution of trimethylamine borane, triethylamine borane, t-butylamine borane, pyridine borane, morpholine borane, sodium borohydride, lithium aluminum hydride or hydrazine to generate in the unexposed areas of the layer chemically reduced metal nuclei which are more highly catalytic to the electroless deposition of a non-noble metal than the light generated nuclei. Non-noble metal is then electrolessly plated selectively on the chemically reduced nuclei to produce a nonreversed image.
摘要:
Processes for producing images by photoexposure, and stable physical developers employing borane reducing agents for use in such processes are described.
