The composite coating comprises a dielectric layer (5) over the ironing plate (4) that has a surface resistance more than 109 ohms; and a static dissipative layer (6) for being in contact with a garment or fabric during ironing disposed on the dielectric layer (5) and in direct contact with the ironing plate (4). The static dissipative layer (6) has a surface resistance less than 109 ohms so that the charges generated on the static dissipative layer (6) during ironing are more easily dissipated from the static dissipative layer (6) through the ironing plate (4) compared to the dissipation of charges from the dielectric layer (5) through the ironing plate (4) in the absence of said static dissipative layer (6). ## Claims ### Claim 1 A coated ironing plate comprising: an ironing plate; and a composite coating applied over the ironing plate, wherein the composite coating comprises: a dielectric layer over the ironing plate, the dielectric layer having a surface resistance more than 109 ohms; and a static dissipative layer for being in contact with a garment or fabric during ironing disposed on the dielectric layer and in direct contact with the ironing plate, the static dissipative layer having a surface resistance less than 109 ohms so that the charges generated on the static dissipative layer during ironing are more easily dissipated from the static dissipative layer through the ironing plate compared to the dissipation of charges from the dielectric layer through the ironing plate in the absence of said static dissipative. ### Claim 2 (depends on 1) The coated ironing plate according to claim 1, wherein the dielectric layer is on the ironing plate. ### Claim 3 (depends on 1) The coated ironing plate according to claim 1, wherein the dielectric layer is selected from a group consisting of an organic-inorganic hybrid polymer layer, a polytetrafluroethylene layer, a porcelain enamel layer, and any combination thereof. ### Claim 4 (depends on 1) The coated ironing plate according to claim 1, wherein the static dissipative layer comprises one or more suitable metal oxides. ### Claim 5 (depends on 4) The coated ironing plate according to claim 4, wherein the one or more suitable metal oxides are transparent conductive metal oxides. ### Claim 6 (depends on 4) The coated ironing plate according to claim 4, wherein the one or more suitable metal oxides are selected from a group consisting of tin oxide, antimony-doped tin oxide, zinc oxide, aluminum-doped zinc oxide, indium tin oxide, indium oxide, cadmium oxide, cadmium tin oxide, and indium-doped cadmium oxide. ### Claim 7 (depends on 1) The coated ironing plate according to claim 1, wherein the ironing plate comprises one of aluminum and stainless steel. ### Claim 8 (depends on 1) The coated ironing plate according to claim 1, wherein the static dissipative layer is in direct contact with one or more edges of the ironing plate. ### Claim 9 (depends on 1) The coated ironing plate according to claim 1, wherein: the ironing plate comprises a steam vent defined by a wall; and the static dissipative layer is in direct contact with the wall defining the steam vent. ### Claim 10 (depends on 1) An electrical appliance for treating garment, the electrical appliance comprising a coated ironing plate according to claim 1. ### Claim 11 A method of forming a coated ironing plate, said method comprising: providing an ironing plate; forming an dielectric layer over the ironing plate, the dielectric layer having a surface resistance more than 109 ohms; and forming a static dissipative layer for being in contact with a garment or fabric during ironing on the dielectric layer and in direct contact with the ironing plate, the static dissipative layer having a surface resistance less than 109 ohms so that the charges generated on the static dissipative layer during ironing are more easily dissipated from the static dissipative layer through the ironing plate compared to the dissipation of charges from the dielectric layer through the ironing plate in the absence of said static dissipative layer. ### Claim 12 (depends on 11) The method of forming the coated ironing plate according to claim 11, wherein forming the dielectric layer comprises applying dielectric material over the ironing plate by spray coating. ### Claim 13 (depends on 11) The method of forming the coated ironing plate according to claim 11, wherein forming the static dissipative layer comprises applying static dissipative material on the ironing plate uncovered by the dielectric layer. ### Claim 14 (depends on 11) The method of forming the coated iron plate according to claim 11, wherein forming the static dissipative layer comprises applying static dissipative material on the dielectric layer and allowing the dissipative material to spread to the ironing plate uncovered by the dielectric layer.
