Patent ID: 7955528

Claim:
A method for preparing a metal-containing film comprising the steps of: coating a conductive ink composition comprising a metal complex compound obtained by reacting at least one metal or metal compound represented by the formula 1 below with at least one ammonium carbamate- or ammonium carbonate-based compound represented by the formula 2, 3 or 4 below and an additive: M n X (1) “M” is a metal or metal alloy, n is an integer from 1 to 10 and X is nonexistent or at least one substituent selected from the group consisting of hydrogen, ammonium, oxygen, sulfur, halogen, cyano, cyanate, carbonate, nitrate, nitrite, sulfate, phosphate, thiocyanate, chlorate, perchlorate, tetrafluoroborate, acetylacetonate, mercapto, amide, alkoxide, carboxylate and derivatives thereof; and where each of R1, R2, R3, R4, R5 and R6 is independently selected from hydrogen; substituted or unsubstituted C 1 -C 30 aliphatic alkyl, cycloaliphatic alkyl, aryl or aralkyl; polymer compound; heterocyclic compound; and derivatives thereof, wherein R1 and R2 or R4 and R5 may be connected with each other to form an alkylene ring with or without a heteroatom, wherein in Formula (2), at least one of R1-R5 is not hydrogen; in Formula (3), at least one of R1-R6 is not hydrogen; and in Formula (4), at least one of R1-R3 is not hydrogen; and treating the same by oxidation, reduction, heat treatment, IR treatment, UV treatment, electron beam treatment or laser treatment.
