1. A heatable laminated side pane for an openable side window of a vehicle, with an upper edge, a lower edge, a front edge, and a rear edge, at least comprising an outer pane and an inner pane, which inner and outer panes are bonded to one another via a thermoplastic intermediate layer,
and a transparent, heatable coating, which is arranged between the outer pane and the inner pane and which is electrically contacted by a first collecting rail and a second collecting rail and which has, for guiding a heating current flowing between the first and second collecting rails, a plurality of decoated isolating lines that run between the first and second collecting rails,
wherein the first collecting rail and the second collecting rail are arranged along the front edge or the rear edge,
wherein heating power increases, at least in one or more sections, from the rear edge to the front edge,
wherein a distance between adjacent isolating lines decreases, at least in one or more sections, from the rear edge to the front edge from a maximum distance in a range between 55 mm and 110 mm to a minimum distance in a range between 10 mm and 55 mm.
