The present invention relates to an ink composition, a kit comprising components of the ink composition, a method of manufacturing a deformable conductor utilizing the ink composition, a deformable conductor obtainable by the method, an electronic device, in particular a wearable and/or stretchable electronic device, comprising the deformable conductor, a method of manufacturing a conductor, a conductor obtainable by the method and an electronic device comprising the conductor. The ink composition comprises a source of transition metal ions, a reducing agent and a polymer and/or a polymer precursor, the polymer precursor comprising a polymerizable terminal multiple bond. The method of manufacturing a deformable conductor comprises the steps of applying the ink composition on at least a part of a surface of a deformable substrate and thermally treating and/or irradiating the ink composition.
