Methods of adhering a castable urethane to a substrate, using the provided adhesives, are also provided.

The present technology provides a reactive hot-melt adhesive including a urethane prepolymer formed from a polyol and a polyisocyanate; and a thermoplastic poly (meth)acrylic resin; the polyol including a bifunctional polyol including polypropylene glycol and polyethylene glycol, a trifunctional polyol, and a polyester polyol having a glass transition temperature of from 20 to 60° C.

The present invention provides polymer blends that can be used in a multilayer structure and to multilayer structures comprising one or more layers formed from such blends. In one aspect, a polymer blend comprises an ionomer of a copolymer comprising ethylene and at least one of acrylic acid and methacrylic acid having a melt index (I.sub.2) of 1 to 60 g/10 minutes, wherein the total amount of ionomer comprises 50 to 99 weight percent of the blend based on the total weight of the blend, and a polyolefin having a density of 0.870 g/cm.sup.3 or more and having a melt index (I.sub.2) of 20 g/10 minutes or less, wherein the polyolefin comprises 1 to 50 weight percent of the blend based on the total weight of the blend, wherein the polymer blend meets the following equation: 3.5<2.76−60*I.sub.2(PO)+308*RVR+0.023*A<4.5 wherein I.sub.2(PO) is the melt index (I.sub.2) of the polyolefin, RVR is the relative viscosity ratio of the polyolefin to the ionomer (I.sub.2(PO)/I.sub.2(ionomer)), and A is the weight percent of ionomer in the polymer blend based on the total weight of the blend.

The present application relates to an optical film and a method for producing a polarizing plate. The present application can provide an optical film satisfying optical and mechanical durability required in a polarizing plate effectively and capable of forming a polarizing plate without causing bending when applied to a display device, and a method for producing a polarizing plate to which the optical film is applied. The present application can provide an optical film capable of realizing the required optical and mechanical durability without causing bending even in a polarizing plate applied to a thin display device and/or a thin polarizing plate, and a method for producing a polarizing plate to which the optical film is applied.
