  • Patent number: 10357921
    Abstract: A process of utilizing a light generating microcapsule to cure a photo-curable material includes dispersing a microcapsule in an interface material that includes a photo-initiator and a photo-curable material. The process also includes applying a stimulus to the microcapsule to trigger a chemiluminescent reaction within the microcapsule. The chemiluminescent reaction generating a photon having a wavelength within a particular emission range that is consistent with an absorption range of the photo-initiator. The photon generated within the microcapsule exits the microcapsule into the interface material to trigger the photo-initiator to initiate or catalyze curing of the photo-curable material.

  • Patent number: 8221960
    Abstract: Images can be provided using a method comprising thermally imaging a negative-working imageable element to provide an imaged element with exposed regions and non-exposed regions, the exposed regions consisting essentially of coalesced core-shell particles, and developing the imaged element on-press to remove only the non-exposed regions using a lithographic printing ink, fountain solution, or both. The imageable element comprises a single thermally-sensitive imageable layer consisting essentially of an infrared radiation absorbing compound and core-shell particles that coalesce upon thermal imaging. The core of the core-shell particles is composed of a hydrophobic thermoplastic polymer, the shell of the core-shell particles is composed of a hydrophilic polymer that is covalently bonded to the core hydrophobic thermoplastic polymer, and the thermally-sensitive imageable layer comprises less than 10 weight % of free polymer.

  • Patent number: 8173346
    Abstract: Affinity transitions from hydrophobic to hydrophilic states, rather than ablation mechanisms, facilitate the creation of an imagewise lithographic pattern on a printing plate. In various embodiments, a lithographic printing member comprises a topmost “imaging” layer that undergoes, in response to heat, a transition from a hydrophobic and oleophilic state to a hydrophilic state (which may or may not also be oleophilic); and a substrate disposed below the imaging layer. The affinity change in the imaging layer may be due essentially to a foaming agent therein. The foaming agent decomposes upon heating, creating a gas that foams the surface of the imaging layer. The resulting spongelike texture enables the surface to retain water, i.e., renders it hydrophilic.
