摘要: A method of forming the aqueous-based shellac dispersion includes dissolving a solution in basic aqueous solvent to form and subsequently combining with an acidic solution, whereby precipitates dispersion. film can be formed by applying suitable surface exposing conditions which cause substantial portion particles fuse, thereby on surface. The does not include any organic for or amine-containing salt. plasticizer employed continuous coating substrate at significantly reduced temperatures.
