    摘要： A composition and method to reduce photolithographic residue and scum formation on a substrate or in a solution, and to reduce or prevent foam formation. The composition contains a diphenyl oxide compound in combination with an antifoam agent. The composition may be added to developer solutions and stripper solutions used in manufacturing printed wiring boards.

    摘要： A negative-acting photoimageable composition useful as a primary imaging resist in the manufacture of printed circuit boards comprises an acid-functional binder polymer, a photopolymerizable component, and a photoinitiator chemical system, in which the binder polymer has an anhydride functional backbone half-esterified with a meth(acrylate) functional hydroxy-terminated oligomer, wherein the meth(acrylate) functionality is separated from the half-ester linkage by at least two alkoxylate groups and at least one ring opened lactone group for improved stripping ability in strong alkaline aqueous stripping solutions, while maintaining good chemical resistance to other processing chemicals, such as alkaline developing solutions, acid etching solutions, and acid plating baths.

    摘要： A negative-acting photoimageable composition useful as a primary imaging resist in the manufacture of printed circuit boards comprises an acid-functional binder polymer, a photopolymerizable component, and a photoinitiator chemical system, in which all or a portion of the photopolymerizable component comprises a (meth)acrylate functional urethane oligomer, wherein the (meth)acrylate functionality is separated from the urethane linkage by at least two alkylene oxide groups and at least one ring-opened lactone group for improved flexibility, tenting strength, fine line adhesion, developer scumming, coupled with unexpectedly improved resistance to processing chemicals, such as alkaline developing solutions, acid etching solutions, and acid plating baths, and stripping ability in strong alkaline aqueous stripping solutions.
