Filed:

Feb 3, 1992

Appl. No.:

7/829371

Inventors:

George R. E. Daniels - Mattapan MA
Michael J. Oddi - Springhill FL
Kevin J. Cheetham - Millbury MA
Stephen S. Rodriguez - Monument Beach MA

Assignee:

Shipley Company Inc. - Marlborough MA

International Classification:

G03C 1725

US Classification:

430280

Abstract:

A photoimageable composition and process for use of the same. The composition comprises a binder that is a mixture of a phenolic resin and a multifunctional epoxy or vinyl ether pound and a curing system comprising a photoactive compound capable of generating a curing catalyst capable of crosslinking the binder components. The process for use of the composition comprises application of the composition to a substrate, drying of the same, exposing the dried coating to activating radiation, curing the binder in light exposed areas, developing the coating and thermally curing the developed image. The composition is especially useful as a solder mask.

G03F 740

US Classification:

430311

Abstract:

A light sensitive composition and process for using said composition. The light sensitive composition comprises a phenolic resin, a multifunctional epoxy or vinyl compound, a photoinitiator and a thermal crosslinking agent. The process for using the same comprises application of the light sensitive composition to a substrate, drying of the same, exposing the dried coating to activating radiation, partially heat curing the coating, developing the coating and thermally curing the developed image. The composition is especially useful as a solder mask.
