  • Publication number: 20180004081
    Abstract: Negatives and laminates containing negatives for exposing liquid photopolymers in UV flexographic plate making are created by printing opaque images directly onto the protective or release cover films used in plate making processes. Combining negatives and cover films in this way eliminates two layers and two interfaces in the exposure process, reducing cost and improving quality.

  • Patent number: 9703198
    Abstract: Negatives, and laminates containing negatives, for exposing liquid photopolymers in UV flexographic plate making are created by printing opaque images directly onto the protective or release cover films used in plate making processes. Combining negatives and cover films in this way eliminates two layers and two interfaces in the exposure process, reducing cost and improving quality. By bringing the negative images as close as possible to the liquid photopolymer, printed dots of “digital quality” are created.

  • Publication number: 20160213593
    Abstract: A laminate of an artificial nail bound to a natural nail with a layer of a cyanoacrylate adhesive formulation containing a thickener, a stabilizer, and a plasticizer is as strong and durable as similar laminates but is flexible and pliable enough to bend without cracking.

  • Publication number: 20150321462
    Abstract: Flexography relief images are produced in currently-available sheet photopolymers by printing them with one inkjet printer pass using solvent-based inks without the need for an inkjet-receptive coating. A solvent ink that will adhere to the surface of the photopolymer slip film with no coating is used and, in embodiments, quick-dried to maximize image quality by heating the inked surface up to about 50° C. In embodiments, sheet photopolymer plates so masked and exposed can then be exposed to UV light in a modified printer that, in effect, transforms a batch process to a continuous one.

  • Patent number: 9023591
    Abstract: A flexography substrate for making I-plates with liquid photopolymers has, in addition to the tie-coat applied to one side to hold the photopolymers in place on the substrate, a micro-porous coating applied to the other side, enabling a masking image to be applied to it using an inkjet printer. In this way, one single sheet of film performs the dual role of substrate and I-plate masking film. By eliminating a sheet of film, the invention provides cost, quality, and environmental benefits.

  • Publication number: 20150097889
    Abstract: The UV opacity from 0 to 100% in one inkjet pass, and the visual color, of solvent-based inks is controlled by the amounts of pigments, dyes, UV blockers and UV brighteners in the inks. The depth-of-cure in photopolymers is controlled by these factors and the % laydown of the ink in one pass.

  • Publication number: 20140318398
    Abstract: An indexing image for craft stamps that is opaque to the eye but transparent to UV light is produced by printing a wavelength-specific solvent-based ink on the stamp substrate. This eliminates the step of printing a separate adhesive-backed indexing image sheet and applying it to the substrate.

  • Publication number: 20140234587
    Abstract: Two methods using two respective laminates produce flexographic printing plates with flat top dots from sheet photopolymers. The methods use a preliminary laminate to isolate the photopolymer surface from the ambient air. A third method enables images to be transferred to non-porous surfaces.

  • Publication number: 20130255517
    Abstract: Solvent-based inks for inkjet printers are prepared by adding UV-absorbers and/or reflectors. These inks, when printed on uncoated or untreated polymeric films which may be either clear or dyed, produce negatives with sufficient opacity to make photopolymer-based flexographic printing plates.

  • Publication number: 20080311323
    Abstract: Disclosed are processes for sterilization of cyanoacrylate adhesive compositions; the compositions, comprising 2-cyanoacrylate ester monomers, so produced and a method for assaying the effectiveness of the sterilization process. A typical process comprises heating the adhesive composition to from about 70° C. to about 140° C. for an effective amount of time. The effectiveness of a process can be assayed by disposing bacterial spores in the cyanoacrylate monomer, exposing the composition to a dry heat sterilization process, transferring the cyanoacrylate composition to a sterile aldose solution, transferring and exposing the sample to a nutrient medium which supports germination and growth of viable spores, incubating the samples, and determining the presence or absence of growth.

  • Patent number: 7309550
    Abstract: This disclosure relates to a photosensitive composition useful in preparing water-developable, relief printing plates and other photosensitive articles. The compositions comprise an unsaturated polyurethane pre-polymer, which is the reaction product of at least one polyether diol, at least one aliphatic diisocyanate, at least one hydroxyl-functionalized mono-, di- and tri-(meth)acrylate, and a particular photoinitiator. The resulting photosensitive resin compositions have reduced rates and levels of yellowing if subjected to additional UV-light or sunlight after processing.
