Patent number: 10303053Abstract: Diazo-resin-containing photoresist compositions and methods of preparing the same are provided for solving the problem that existing diazo-resins cannot be applied in LCD photoresists because the storage periods of the diazo-resins themselves and the printed boards made thereby are both short due to poor thermal stability of the diazo-resins. The diazo-resins of the present invention have excellent thermal stability and exhibit strong resistance to dry etching when being used in negative photoresists, while high resolution can be achieved.

Patent number: 6861196Abstract: The present invention includes an imageable element, which can be: (a) an imageable element comprising an imaging layer which comprises: an aromatic diazonium salt containing compound having an alkoxy substituent and an aromatic diazonium salt containing compound free of an alkoxy substituent; a polyvinyl acetal binder; and a sheet substrate; or (b) an imageable element comprising an imaging layer which comprises: an aromatic diazonium salt containing compound having an alkoxy substituent and an aromatic diazonium salt containing compound free of an alkoxy substituent; and a sheet substrate. The imaging layer includes a total aromatic diazonium salt containing compound content of at least 10 weight percent. The molar ratio of the aromatic diazonium salt containing compound having an alkoxy substituent to the aromatic diazonium salt containing compound that is free of an alkoxy substituent is from about 1.0:1 to 70:1. Upon imagewise exposure and development, an imaged element is obtained.Type: GrantFiled: September 17, 2003Date of Patent: March 1, 2005Assignee: Kodak Polychrome Graphics LLCInventors: Stephan J. Platzer, Maria T. Sypek, Paul Perron, Harald Baumann, Melinda Alden
