ABSTRACT:
Disclosed is a stabilizer composition effective to protect PVC resin against heat-mediated deterioration, comprising a mixture of barium and zinc salts of aliphatic C.sub.6 -C.sub.20 carboxylates and aromatic C.sub.7 -C.sub.12 carboxylates, organic triphosphites of the formula R.sub.1 OP(OR.sub.3)OR.sub.2 wherein each of R.sub.1, R.sub.2 and R.sub.3 is C.sub.6 -C.sub.12 alkyl or phenyl, and organic acid phosphites of the formula R.sub.4 OP(OH)OR.sub.5 wherein each of R.sub.4 and R.sub.5 is C.sub.6 -C.sub.12 alkyl or phenyl, or R.sub.4 can be hydrogen. PVC film compounded with this stabilizer composition also exhibits improved wettability and adherence to water-based inks applied to such films.
