ABSTRACT:
A microporous material substrate is coated with a coating composition comprising a volatile aqueous liquid medium and binder dissolved or dispersed in the volatile aqueous liquid medium, wherein the binder comprises film-forming organic polymer comprising: (a) water-soluble poly(ethylene oxide) having a weight average molecular weight in the range of from 100,000 to 3,000,000, and (b) water-soluble or water-dispersible crosslinkable urethane-acrylate hybrid polymer. Finely divided substantially water-insoluble filler particles may optionally be present in the coating composition. After drying and crosslinking, the peel strength between the coating and the microporous material substrate is high. The coating may be inkjet printed. The printed coating may be coated by or laminated to a substantially transparent protective layer.
