ABSTRACT:
This invention relates to polymerized polymeric vinyl films containing a minor portion of an anti-fogging and anti-tackifying agent, said agent comprising a partial ester of a water soluble C.sub.2-6 polyol with a C.sub.12-18 aliphatic monocarboxylic acid, a polyalkoxylated derivative of a partial ester of a water soluble C.sub.2-6 polyol with a C.sub.12-18 aliphatic monocarboxylic acid, the alkoxy groups therein having each 2-3 carbon atoms and the number of alkoxy groups being about 3-30 per molecule of said alkoxylated partial ester and in combination with both or each of the aforementioned partial esters, polyalkoxylated alkyl phenol, the alkoxy groups therein having each 2-4 carbon atoms and the number of alkoxy groups being about 3-50 per molecule.
