Abstract
The invention concerns a novel cross-linkable composition and its use for preparing novel polyurethane films. The cross-linkable composition comprises (a) 20 to 50 wt. % of polyisocyanate, (b) 50 to 80 wt. % of acrylic oligomer containing hydroxyl groupings whose content in weight relative to the acrylic oligomer is between 2.5 and 4.5% and (c) 1 to 10 wt. % of a silicon fluid of formula (1).
