Zusammenfassung: | The present invention relates to a thin film composition using conductive metal ink capable of improving light absorption ability and easily performing light sintering. The present invention relates to the thin film composition using conductive metal ink which is formed on an upper end of a substrate. The thin film is formed by coating mixed ink of transition metal ink and silver ion ink on the upper end of the substrate, and provisional drying and light sintering the same. The transition metal ink includes: 5-80 parts by weight of a transition metal-glycol copolymer complex compound manufactured by reacting a transition metal precursor with a glycol copolymer; 10-40 parts by weight of a solvent; 0.05-1.0 part by weight of an oxidizing agent; and 0.1-5.0 parts by weight of a dispersant. The silver ion ink includes: 5-80 parts by weight of a silver ion-glycol copolymer complex compound manufactured by reacting a silver oxide with a glycol copolymer; 10-40 parts by weight of the solvent; 0.05-1.0 part by weight of the oxidizing agent; and 0.1-5.0 parts by weight of the dispersant. After the provisional drying, a thin film includes 5-50 wt% of a silver part of the ion ink based on the total weight, and the remaining is formed by a transition metal part.
