Problems solved by technology

Photolithography, however, is a complex, multi-step process that is too costly for the printing of electronic devices on plastic substances.
SAM printing is capable of creating high resolution patterns, but is generally limited to forming metal patterns of gold or silver for example using thiol chemistry.
The industry has been pursuing these goals for many years with limited success and continued research is being done to achieve th

invention example 1

[0184]PChem PFI-722 ink was applied two times as described above with an eight second wait between applications. The plate was then inked with the water based Performa SP4C Process Black XGL044113 Black ink that had been modified for flexibility by mixing it 1:1 with “Versaflex 9”. This ink was also allowed to dry at least 8 seconds before the resulting multilayer structure was transferred onto a Carboset® 525-coated receiver element. After the third application noted above, the plate cylinder with the attached elastomeric relief element containing the multilayer structure was removed and impressed against a provided heated receiver element to provide a printed pattern of the multilayer structure.

invention example 2

[0188]PChem PFI-722 ink was applied as described above twice with an eight second wait between applications. Versaflex 9 was then applied to the elastomeric relief element over the PChem PFI-722 ink, and was allowed to dry at least 8 seconds before the resulting multilayer structure was transferred to provide a printed pattern of the multilayer structure on an uncoated PET receiver element as described above.

invention example 3

[0192]PChem PFI-722 ink was applied as described above two times with an eight second wait between applications. The elastomeric relief element was then inked with Versaflex 9 that had been mixed 1:1 with Performa SP4C Process Black XGL044113 Black ink. The resulting latex ink mixture is also allowed to dry at least 8 seconds after its application. The resulting multilayer structure was then transferred to form a printed pattern on an uncoated PET film receiver element as described above. This Example demonstrates the ability to transfer a black grid (printed pattern) onto an uncoated PET film. However, the resulting grid lines were less continuous and it was not possible to measure pattern conductivity of the grid. The grid lines, when viewed through the backside of the PET film were less visible.

Abstract

A multilayer structure having at least two different print materials pattern is formed on a receiver element using an elastomeric relief element having a relief pattern. Multiple different printable material compositions are sequentially applied only to the uppermost relief surface of the elastomeric relief element and at least at least 50 weight % of a carrier liquid is removed from each printable material composition. During contact of the multilayer structure on the uppermost relief surface and the receiver element, the elastomeric relief element is compressed by at least 10 μm of its original thickness. The elastomeric relief element is then separated from the receiver element to leave a pattern of the multilayer structure on the receiver element, wherein at least 70 weight % of the multiple print materials is transferred to the receiver element.

RELATED APPLICATIONS[0001]Reference is made to the following copending and commonly assigned patent applications, the disclosures of which are incorporated herein by reference:[0002]U.S. Ser. No. 14 / 150,118 filed Jan. 8, 2014 by Zwadlo, Fohrenkamm, and Simpson as a Continuation-in-part application of U.S. Ser. No. 13 / 759,092, filed Feb. 2, 2013, now abandoned; and[0003]U.S. Ser. No. 14 / 134,085 filed on Dec. 19, 2013 by Fohrenkamm, Simpson, and Zwadlo.FIELD OF THE INVENTION[0004]This invention relates to a method for forming or printing a print material in a printable material composition onto a suitable receiver element to provide a printed pattern. This printing method is carried out using an elastomeric relief element to apply (for example, laminate print) at least two different print materials in different printable material compositions to a receiver element after at least some of the volatile carrier liquid is removed from the multiple printable material compositions.BACKGROUND...
