Claim:
1. A method comprising: a. providing a hot melt composition comprising one or more non-aromatic cyclic (alkyl)acrylates, one or more waxes chosen from candelilla waxes, esterified montan waxes, ozokerite waxes, ceresin waxes, synthesized hydrocarbon waxes and hydrogenated waxes comprising an acid number of 0 to 30 mg KOH/g, wherein the one or more waxes are in amounts of 5 wt % to 30 wt % and one or more radical initiators; b. selectively depositing the hot melt composition on a substrate; c. applying actinic radiation to the hot melts composition to cure the composition; d. etching sections of the substrate not covered with the cured hot melt composition; and e. removing the cured hot melt composition from the substrate with a base comprising a pH of 11 or greater to form a patterned article.
