摘要:
A water-insoluble electroconductive coating, which will allow subsequent coatings such as ZnO or dielectric resins to be applied from an aqueous-based system, is applied to a substrate as a double coating; a strong cationic polymer followed by a strong anionic polymer or vice versa. This results in the formation of a polysalt at the interface that is both water-insoluble and electroconductive.
摘要:
Cellulosic fibrous material impregnated with ink, e.g. newprint, is deinked by stirring it with water in the presence of an admixture of a non-ionic surfactant and ethylene glycol.
摘要:
Electroconductive articles such as paper have a coating consisting essentially of (1) a barrier coating comprising a copolymer of ethylene and vinyl acetate, a styrene- butadiene latex, sodium alginate or a fluorocarbon with starch or a modified starch; and (2) an electroconductive coating. Such articles are made by applying the barrier coating to a substrate, allowing it to dry, applying the electroconductive coating over the barrier coating and allowing it to dry.
摘要:
An electroconductive polymer composition contains from 90 to 99.9 percent of a water-soluble electroconductive polymer and from 0.1 to 10 percent of an organic silicone component, the percentages being by weight based on the total weight of the polymer composition, the silicone component being present to impart improved tack properties to paper coated with the composition.
