    摘要: The invention provides a way of using cellulose triacetate (CTA) made from softwood pulp to make films suitable for use in liquid crystal displays (LCDs). It has been surprisingly found that a combination of certain additives in the film casting dope and of metal and sulfur content of the CTA allow a softwood CTA to exhibit peeling characteristics from the casting substrate that are similar to those of lint-based CTA of similar sulfur content. The additives include a combination of acid scavengers and chelating agents.
