Dye system or ink jet record medium for pigment type ink jet ink

摘要

The coating composition which this invention regards the medium seat for ink jet printing which from in order that the medium backing material and ink reception layer is formed is formed to the medium backing material is applied. Ink reception layer, half the sum being attached or the particulate of metallic oxide, at least can include the water soluble coating compound additive, and the binder of 5wt%. In addition as for the medium seat, it possesses the washing conductivity under approximately 80 micro siemens/centimeter, here, particular washing conductivity, while agitating the medium seat sample of 100cm2 in deionization underwater, is decided 45 second infix after being, by measuring the conductivity of 50mL bath of the said deionized water at room temperature. Selective figure It is not
