example 1
[0051] Experimental fluorosilicone obtained from Wacker Silicones (Wacker FS) was formulated into several crosslinked fluorosilicone elastomer samples. The formulation contains two parts (see below): Part A is a vinyl terminated trifluoropropylmethylsiloxane polymer; and Part B is a methylhydrogensiloxane-trifluoropropylmethylsiloxane crosslinked agent.
[0052]
[0053] The coating chemistry is based on platinum-catalyzed addition curing of two components (polymer containing vinyl groups and crosslinker containing Si-H groups) via a hydrosilylation reaction. The main variants of the experimental formulations were: 1. Wacker FS - unfilled fluorosilicone; 2. Wacker FS - 10% carbon black (CB); and 3. Wacker FS - 10% black iron oxide (black IO).
[0054] In a representative reaction, the indicated amount of IR filler material (iron oxide or carbon black) was dispersed in the solvent trifluorotoluene (TFT) and tumbled overnight in a ball mill jar. Then, Part A (polymer) and t...

Abstract
This disclosure is directed to a material composition that may be usable as a surface component in a plate design for use in variable data digital lithographic image forming devices. The disclosed material composition incorporates infra-red (IR) absorbing filler materials, including carbon black filler material particles in a fluorosilicone polymer or elastomer. The inclusion of the disclosed carbon black material compositions promotes precise heating in a patterning step for a layer of dampening fluid while minimizing harmful byproduct emissions including emissions of trifluoropropionaldehyde(TFPA) resulting from localized heating of a principally fluorosilicone imaging layer. The disclosed homogeneously-dispersed carbon black particles are particularly usable for improving operational characteristics of fluorosilocone-based reimageable surface layers of imaging members employed in the variable data digital lithographic image forming devices.
Description
technical field [0001] The present disclosure relates to carbon black-based additive formulations and methods for producing these formulations suitable for inclusion in intermediate transfer and reimageable surfaces of imaging members in digital lithographic image forming systems. In particular, the disclosed embodiments relate to the incorporation of carbon black filler materials into various marking and printing system components, such as imaging members or intermediate transfer members specifically formed for use in a new class of variable data digital lithographic image forming devices . Background technique [0002] Lithographic and offset image formation is generally understood as a printing process for preforming high quality multicolor images on a wide variety of image receptor media substrates. For the purposes of this disclosure, the terms "printing," "marking," and "imaging" are used interchangeably. In a typical lithographic image forming process, the image tra...
