Abstract (en)
[origin: WO9849214A1] Novel nitrogen-containing epoxy resin compositions suitable for photoimageable coating applications such as solder mask coating formulations are prepared by advancing an epoxy resin such as epoxy novolac resins with a nitrogen-containing compound such as diphenylmethane diisocyanate; then acrylating the advanced epoxy resin with an acrylation material such as acrylic acid, and then esterifying the advanced acrylated epoxy resin such as a novolac acrylate with an anhydride such as methylhexahydrophthalic anhydride.
