    • A progressive power lens 10 for spectacles has a distance portion 11 and a near portion 12 of different powers. A surface power OMHP in a horizontal direction on an object-side surface along a principal meridian 14 or a vertical reference line passing through a fitting point Pe, a surface power OMVP(y) in a vertical direction of the object-side surface, the absolute value IMHP of a surface power on an eye-side surface, and the absolute value IMVP of a surface power in a vertical direction on the eye-side surface satisfy the following condition. OMHP(y)>OMVP(y) IMHP(y)>IMVP(y) OMHP(y)−OMVP(y)=IMHP(y)−IMVP(y) In the conditions, y is a coordinate along the principal meridian or the vertical reference line.

    • An aqueous polyurethane resin dispersion is a dispersion of a polyurethane resin in an aqueous medium, the polyurethane resin being obtained by reacting (A) a polyurethane prepolymer obtained by reacting (a) a polyisocyanate compound, (b) a polyol compound including a polycarbonate polyol with a number average molecular weight of 400 to 3000, (c) an acidic group-containing polyol compound and (d) a blocking agent, with (B) a chain extender, the total content of urethane bonds and urea bonds being 7 to 15 wt%, the content of carbonate bonds being 15 to 40 wt%, the content of ether bonds being 0.5 to 5 wt%, the content of isocyanate groups bonded to the blocking agent being 0.2 to 2.0 wt%, each of these contents being based on solid contents, the acid value being 10 to 16 mg KOH/g. The aqueous polyurethane resin dispersion can form coating films which permit new application while exhibiting excellent water resistance and solvent resistance. A coating composition includes the dispersion. A polyurethane resin film is obtained by thermally drying a composition including the dispersion.
