| 摘要 |
There is described an aqueous coating composition for a plastic film which comprises (a) from 40% to 60% (by dry weight) of a binder resin (such as a PVdC:/ EEA copolymer; vinylidene chloride / vinyl chloride copolymer; vinyl acetate / ethylene copolymer; and/or a vinyl acetate / ethylene / vinyl chloride terpolymer); and (b) from 60% to 40% (by dry weight) of ink receptive filler particles (such as PVC, precipitated silica, calcium carbonate, sodium aluminosilicate and/or sodium magnesium aluminosilicate) and has a mean particle size of 10 nanometres (0.01 microns) to about 5 microns. Preferably the filler particles are at least partially soluble in the binder resin. Films (such as primed BOPP) which are top coated with such compositions are printable with solvent piezo ink-jettable inks. |
