Abstract (en)
Paper printed with ink is covered with a protective coating whose composition essentially consists of water, 15-45 wt% (preferably 20-30 wt%) of at least one emulsified acrylic (co)polymer of the air-drying or UV-curing type, and when using an air-drying acrylic (co)polymer 0.8-2.0 wt% (preferably 1.2-1.6 wt%) of wax (preferably polyethylene wax), in addition to the usual additives. Said composition is applied on printed paper (particularly on thin paper, i.e. 100 g/m2 or lower, generally 75 to 95 g/m2) in an amount such as to obtain a dry film weight of 1.5-5 g/m2 (preferably 2-3 g/m2) then subjected to air-drying followed where applicable by UV-curing. Acrylic (co)polymers of the UV-curing type are preferred because they provide more resistant coatings.
