In the present invention, under conductive layer 6 situation, also can be with black layer conductive layer 2 in the part formation except that power supply of conductive layer 6 for layer with the conductive pattern that possesses power supply.
Under the situation that will form as linear pattern such as wiring circuit or antenna pattern with black layer conductive layer 2, the line width of preferred black layer 5 is wideer than the live width of conductive layer 6.The pattern width of preferred black layer 5 is than more than the wide 0.2mm of the pattern width of conductive layer 6.Under the situation of not enough 0.2mm, consider from the problem of printing precision or positioning accuracy, think can produce conductive layer 6, but be not limited to above-mentioned preferred range from problems such as black layer 5 expose.
For slug type transfer film of the present invention, through in the stacked on top of one another of band black layer conductive layer 2 by the resin bed that forms through the removable organic matter of sintering, can further improve transfer printing property.As resin bed, can be provided for the adhesive linkage 8 of substrate bonding such as glass, be used to prevent that adhesive linkage 8 from immersing the intermediate layer 7 of conductive layers 6 or black layer 5 etc., being used to prevent protective layer 4 that the mechanicalness of conductive layer 6 and black layer 5 after the transfer printing construction is damaged etc.
As the used adhesive linkage 8 of the present invention, not special the qualification, but so long as to baseplate-laminating the time, have the organic matter that the sintering of the cementability of appropriateness removes and get final product, can use bonding agents such as the acrylic acid series that has cementability at normal temperatures, rubber system.In addition, under the situation of constructing, also can use the organic matter that under laminating temperature, softens through heat lamination etc.Adhesive linkage 8 also can be according to the mode of cover tape black layer conductive layer 2, on whole of the film substrate with fissility 1, forms, also can form with the identical pattern of black layer conductive layer 2.
Adhesive linkage 8 can be that the mode of 1～20 μ m, preferred 2～10 μ m forms according to thickness.Think when thickness less than 1 μ m, bonding force deficiency and the reduction of transfer printing property, when thickness during greater than 20 μ m, the generation of thermal decomposition gas increases, and therefore, band black layer conductive layer 2 is easy to generate defective, makes sintering bad easily, but is not limited to above-mentioned preferred range.The thickness of adhesive linkage 8 preferably in the scope that can keep bonding force, forms film as far as possible.
The present invention can be provided with intermediate layer 7 between band black layer conductive layer 2 and adhesive linkage 8.The effect to the immersion of band black layer conductive layer 2 of solvent that the employed bonding agent of the formation that prevents adhesive linkage 8 contains and organic matter can be taken in intermediate layer 7.

Among the present invention, on the band black layer conductive layer 2 before the sintering on being transferred to substrate, to prevent to adhere to foreign matter damage etc. taking place is purpose, and protective layer 4 can be set.Band black layer conductive layer 2 before the sintering because be mostly conductive material or the content of the inorganic pigment composition that black pigment, frit are such is many, organic bond contain proportional few situation, therefore, hard, the crisp trend of membranous existence that sintering is preceding.Therefore, when making transfer film crooked, crackle takes place in band black layer conductive layer 2 easily.Therefore, protective layer 4 also can be taken on the effect of the generation that prevents with film the crackle when crooked etc.
As the material that protective layer 4 uses, not special the qualification, but so long as the organic matter that sintering is removed get final product, can from the organic matter identical materials of conductive layer or black layer use select.
Protective layer 4 also can be according to the mode of cover tape black layer conductive layer 2, on whole of the film substrate with fissility 1, forms, also can form with the identical pattern of black layer conductive layer 2.The thickness of protective layer 4 is preferably 3～6 μ m.
According to an embodiment of the present invention, seize the formation of being with black layer conductive layer 2 on both sides by the arms, therefore, improved bendability, improved construction operation property to the applying of substrate or transfer printing etc. owing to can be set at protective layer 4 and intermediate layer 7.In addition; Even form the situation of band black layer conductive layer 2 with shapes such as fine rule or round dots, also can have the mode of 1 whole of the film substrate of fissility according to covering, form protective layer 4 or intermediate layer 7, adhesive linkage 8; Thus; Do not rely on the pattern form or the size of band black layer conductive layer 2, can increase the contact area with substrate, can keep bonding force fully.In addition, because the present invention is the technology of having utilized the transfer printing type film, therefore, having also can a plurality of band black layer of primary transfer conductive layer 2, can also improve advantages such as positional precision.
Among the present invention,, can use application pattern such as mode of printing such as serigraphy or hectographic printing or gravure coating as the method for each layer that on the film substrate with fissility 1, forms transfer printing layer 3.Under the situation that forms pattern, suitably use printing process.In addition, under the situation that forms same layer on the broad area, also suitably use coating method.
When on the film substrate with fissility 1, forming each layer of transfer printing layer 3, can make and use inorganic pigment that each layer contained or organic matter to disperse or dissolve in the solvent and the coating liquid (cream) that forms.As solvent; Consider inorganic pigment dispersed and organic dissolubility, be suitable for the boiling point of printing process etc.; Can be separately or mix that to use water system, alcohol system, ketone system, fat system, ether system, hydrocarbon be equal solvent; As required, bubble countermeasure and viscosity when printing in order to regulate also can be used additives such as antifoaming agent or tackifier.Solvent or additive can use volatilization when on the film substrate with fissility, forming each layer of transfer printing layer, or can volatilize or decompose the material of removing through sintering.
