A method of making a polarizing article having high polarization efficiency, low haze, and no visible micro-cracks. The article is made by applying an aqueous polarizing dye solution to a surface of a substrate. The polarizing dye solution comprises at least one ammonium salt of a polarizing azoic dye, an activator, and at least one of an acid and a non-polarizing azoic dye.
