A Study on the Effect of a Surfactanct Additive on the Performance of a Thermo-sensitive Imaging Material
Abstract:This paper is concerned with the improvement of the combined properties of a phenolic resin-based thermal imaging composition. A surfactant-like additive, stearamide, was introduced to the imaging material. When drying, the surfactanct material will move to the surface of the thermo-sensitive film to form a very thin layer due to the low surface energy. The thin layer was the so-called monolayer. It can be broken by the infrared laser and developed together with the resin of the exposed area. However, the unexposed area will be protected by this thin layer. As a result, the difference between the exposed area and unexposed area became larger, and the image tolerance and image quality were improved.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
