A glass frit for forming a black enamel coating comprising
- Si at 6.5 mol % to 6.9 mol %, B at 9.0 mol % to 9.3 mol %, Bi at 13.0 mol % to 13.4 mol %, Zn at 6.0 mol % to 6.3 mol %, and Al at 1.5 mol % to 2.0 mol %, and
- Co, Ni, and Fe, wherein a total amount of Co, Ni, and Fe is 2.9 mol % to 3.5 mol % of the glass frit in a molar ratio.
A coated article comprising:
- a transparent substrate, a multilayer thin film coating disposed on the transparent substrate, and a patterned portion having a black enamel coating formed on at least part of the transparent substrate as a predetermined pattern,
- wherein the multilayer thin film coating includes a first dielectric layer, a metallic functional layer having an infrared reflection function, and a second dielectric layer, which are sequentially disposed in a direction away from the transparent substrate, and
- the black enamel coating is formed from a glass frit comprising Si at 6.5 mol % to 6.9 mol %, B at 9.0 mol % to 9.3 mol %, Bi at 13.0 mol % to 13.4 mol %, Zn at 6.0 mol % to 6.3 mol %, Al at 1.5 mol % to 2.0 mol %, and Co, Ni, and Fe, wherein a total amount of Co, Ni, and Fe is 2.9 mol % to 3.5 mol % of the glass frit in a molar ratio.
A method for manufacturing a coated article, comprising:
- printing a composition for forming a black enamel coating so as to have a predetermined pattern on at least part of a transparent substrate having a multilayer thin film coating thereon;
- and
- forming a patterned portion including the black enamel coating by carrying out a heat treatment of the transparent substrate on which the multilayer thin film coating and the composition for forming the black enamel coating are formed,
- wherein the composition for forming the black enamel coating comprises a glass frit comprising Si at 6.5 mol % to 6.9 mol %, B at 9.0 mol % to 9.3 mol %, Bi at 13.0 mol % to 13.4 mol %, Zn at 6.0 mol % to 6.3 mol %, Al at 1.5 mol % to 2.0 mol %, and Co, Ni, and Fe, wherein a total amount of Co, Ni, and Fe is 2.9 mol % to 3.5 mol % of the glass frit in a molar ratio, and an organic vehicle, and
- the multilayer thin film coating comprises a first dielectric layer, a metallic functional layer having an infrared reflection function, and a second dielectric layer, which are sequentially disposed in a direction away from the transparent substrate.
