The invention relates to a method for producing a grain-orientated electric steel which is coated with a phosphate layer and in which there is applied to the electric steel a phosphate solution which contains a colloid component and at least one colloid stabilizer (A) and/or at least one pickling inhibitor (B), the phosphate solution containing at least one compound which has chromium in the oxidation stage III (chromium (III) compound). Grain-orientated electric steel produced with the method according to the invention is distinguished by excellent optical properties and a high tensile stress.
