  • Waterborne photoresists having polysiloxanes
    Patent number: 5387494
    Abstract: A waterborne photoimageable composition or photoresist comprises a latex binder polymer having sufficient carboxylic acid functionality to render it developable in alkaline aqueous solution, a photopolymerizeable monomer fraction, a photoinitiator chemical system and a poly(siloxane(s)).
    Type: Grant
    Filed: March 30, 1994
    Date of Patent: February 7, 1995
    Assignee: Morton International, Inc.
    Inventors: Robert K. Barr, Gene A. Derrico
  • Process of using a flexible, fast processing photopolymerizable composition
    Patent number: 4610951
    Abstract: A photopolymerizable composition comprised of an addition polymerizable material, a photoinitiator, a thermal addition polymerization inhibitor and a polymeric binding agent. The addition polymerizable material is comprised of a defined monoethylenically unsaturated acrylate and one or more non-gaseous compounds having at least two terminal ethylenic groups. The photopolymerizable composition displays superior flexibility and develops and strips more efficiently when compared to a like composition but in the absence of the acrylate. The photopolymerizable composition may be in the form of sheet or roll on a film support which can be laminated to a substrate and can be used in the preparation of printed circuit boards.
    Type: Grant
