Abstract
A multilayer film includes a substrate layer; a surface protective layer integrally laminated on a first surface of the substrate layer, the surface protective layer containing a polyurethane which is a reaction product of a polyol (P) having a hydroxyl value of 25 to 380 mgKOH/g and a content of fluorine atoms of 0.01 to 20% by mass and a polyisocyanate (I); and an adhesive layer integrally laminated on a second surface of the substrate layer. Also described is a two-liquid curable coating agent for forming the surface protective layer.
