|20140234587||Methods of Producing Flat Top Dots on Flexographic Printing Plates, and Laminates Therefor - 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.||08-21-2014|
|20140162192||Photopolymer Imaging from Solvent Ink Film Images - 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.||06-12-2014|
|20140080042||Printable Laminates for Flexo Plates, Methods of Making, and Methods of Using - 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.||03-20-2014|
|20130255517||Solvent-Based Inkjet-Printed Negatives for Making Flexo Plates - 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.||10-03-2013|
|20080311323||Cyanoacrylate Adhesive Compositions and Devices and Process for Sterilization Thereof - 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.||12-18-2008|
