ABSTRACT:
Negative photoimageable compositions are disclosed which contain a radiation sensitive component for producing an acid when subjected to radiation at wavelengths of 320 to 420 nanometers, a resin binder and a reactive oligomer. The compositions are useful in constructing printed circuits and integrated circuit packages.
