Abstract
In production of solid films (e.g. a floor covering wear layer) from vinyl chloride polymer plastisols, good physical properties of the plastisols and films are provided by use of a plasticizer containing 50-90% prime ester at least about 40 parts per hundred parts by weight of which is aromatic diester selected from alkyl benzyl succinates, glutarates and mixtures thereof, up to 20% hydrocarbon boiling at 200.degree.-325.degree. C. and 10-50% non-aromatic diester having a molecular weight of 230-300. Using such a plasticizer, the plastisols and films can be conveniently plasticized with relatively small amounts of prime ester, and the films containing such small amounts of prime ester have unusually high stain resistance.
