1. a method of making Thinfilm pattern, comprising:

  • Solution against corrosion is injected in the blanket in print roller, and wherein said solution against corrosion comprises printing solvent, the described printing solvent 6>


    that satisfies condition solventor δ


    11, wherein δ

    solventthe solubility parameter of described solvent, or the 6<


    that satisfies condition solvent<

    11 and μ


    2 (D), the dipole moment that wherein μ

    is described solvent;

    Rotate described print roller so that described solution against corrosion is evenly coated on described blanket;

    On forme, roll and be coated with the described print roller of described solution against corrosion, thereby so that described solution composition against corrosion is formed to corrosion-resisting pattern;

    Described corrosion-resisting pattern is transferred to substrate from described print roller, and described substrate has a metal level;

    Described corrosion-resisting pattern hardens;

    AndUse the described metal level on described this substrate of corrosion-resisting pattern etching and remove described corrosion-resisting pattern to form required Thinfilm pattern on this substrate;

    Wherein said solution against corrosion comprises;

    Based polyalcohol, wherein said based polyalcohol comprises at least one in xylenols and pseudocuminol, wherein said xylenols is described pseudocuminol is and the molecular wt of described based polyalcohol is in 2000 to 100000 scopes;

    Printing solvent, wherein, described printing solvent comprises any or its combination in 1-methyl 1-2-pyrrolidone, diphenyl ether and propylene carbonate;

    Carrier solvent, described carrier solvent is any or its combination in methyl alcohol, ethanol, isopropyl alcohol and butanols;

    By stearic acid, palmitic acid, 12 (alkane) acid, octadecenic acid, dioctyl (2-ethyl) sulfosuccinate, phosphate, CF 3(CF 2) 4(CH 2cH 2o) 10or CF 3(CF 2) 5cH 2cH 2o) 14in at least one surfactant of making;

    By based on two (4-N-N-dimethylamino-phenyl)-2-fluorophenyls)-methane and/or two (4-N-N-dimethylamino-phenyl)-2-fluorophenyl) dyestuff made of acetyl;

    The content of wherein said based polyalcohol is 30wt%, the content of described printing solvent is in 10vol% arrives the scope of 50vol%, the content of described carrier solvent is in 50vol% arrives the scope of 90vol%, the content of described surfactant is at 0.01wt% in the scope of 3wt%, and the content of described dyestuff is in 0.01wt% arrives the scope of 1wt%.
