Abstract
Hot melt compositions include non-aromatic cyclic (alkyl)acrylates and low acid number waxes. Upon application of actinic radiation, the hot melt compositions cure to form resists. They may be stripped from substrates with high alkaline strippers. The hot melt compositions may be used in the manufacture of printed circuit boards and photovoltaic devices.
