Abstract
A vinyl resin composition is obtained by mixing the vinyl resin with plasticizer in combination with three surfactants, namely, a partial aliphatic glycerine ester, a partial aliphatic ester of sorbitan and a polyalkoxylated alkyl phenol to produce a composition which has excellent antifogging and antiblocking properties and is more readily sheeted in the film than compositions without these three surfactants.
Claims1
A vinyl resin composition containing 100 parts of vinyl resin, 10 to 80 parts of plasticizer and in combination 0.5 to 50 parts of a partial ester of glycerine and an aliphatic, saturated or unsaturated, monocarboxylic acid containing 8 to 18 carbon atoms, 0.5 to 50 parts of a partial ester of sorbitan and an aliphatic, saturated or unsaturated, monocarboxylic acid containing 8 to 18 carbon atoms and 0.5 to 50 parts of a polyethoxylated alkyl phenol, where the alkyl group contains 8-12 carbons, with an average of 4-20 moles of ethylene oxide.
