Abstract

Metallized paper whose metal layer has been deposited by evaporation in vacuo onto a cast-coated paper. The cast coating contains mineral pigments, latex binders and conventional additives, and at least 5 parts by weight of the pigment are a synthetic polymer pigment. The coating material has a pH value >7 and during the process of fabricating the metallized paper it is deposited in such an amount that, after the drying, 10-30 g/m.sup.2 of cast coating are present. The coating material deposited onto a paper web is dried until its moisture content is 5-15% and the web is then pressed with the coated paper surface against a drum with a highly polished surface at a temperature of 100.degree.-160.degree. C. by means of a roll with a nip >1000 N/cm.
