Abstract
This invention relates to an improvement in a mixture which is polymerizable by radiation and contains, as the essential constituents, (a) a polymeric binder, (b) a polymerization initiator which can be activated by radiation, and (c) a compound of the formula I ##STR1## in which R.sub.1 is a divalent aliphatic group having 1 to 15 carbon atoms which also can be partially replaced by hetero-atoms, a divalent cycloaliphatic group having 3 to 15 carbon atoms, or a mixed aliphatic-aromatic group having 7 to 15 carbon atoms, and A is an electron-attracting radical. The invention also relates to a radiation-sensitive resist material using the improved radiation-polymerizable mixture.
