  • Method and composition for reducing waste in photo-imaging applications
    Patent number: 8871133
    Abstract: Waste reduction, including hazardous waste reduction in photoimaging processes can be accomplished by improving diffusional resolution of cationic curable compositions. The addition of fluorinated polymers including fluorinated surfactants provides improved diffusional resolution in cationic and/or radical based photoimaging formulations allowing for image accuracy improvements, and reduced product and process waste quantity and disposal cost. These fluorinated surfactants also allow for increased cure speed, and non-hazardous constituent formulations that result in less wasted material and time.
    Type: Grant
    Filed: March 20, 2012
    Date of Patent: October 28, 2014
    Assignee: DSM IP Assets B.V.
    Inventors: John Lawton, Jigeng Xu, John Southwell, Gordon Smith, Willem D. Weenink
