  • Patent number: 10384441
    Abstract: An apparatus and method of manufacturing a fluorosilicone composite for a variable data lithography imaging member surface layer. Examples of the fluorosilicone composite include a first part and a second part, the first part having fluorosilicone, carbon black, silica and butyl acetate, the second part having a platinum catalyst, a crosslinker, butyl acetate and an inhibitor. The first part may also include a dispersant (e.g., a polyoxyalkylene amine derivative) that removes a need for shaking the dispersion by paint shaker and instead allows a more manufacture friendly roll ball milling process. The dispersant will also help in stabilizing the fluorosilicone composite for scaled up production.

  • Patent number: 8820541
    Abstract: A method for producing a curable composition for imprints includes the step of passing a curable composition containing a polymerizable monomer (A) and a polymerization initiator (B) through a filter having an effective filter area of 200 cm2 or more at least one time. The method suppresses pattern-peeling when peeling the mold employed in forming a pattern using the curable composition for imprints, and thus provides excellent patternability.
