After, electrode pattern formed on a protective film forming, and forming a protective layer number 1 and number 2, number 2 on a protective film forming acrylic adhesive layer, thickness of 50 micro m to attach and hold the polycarbonate substrate, film touch sensor was under trillion number.

Experiment e.g.

(1) bending crack evaluation

In the embodiment and comparison the first deoxygenator film touch sensor 100 mm x 10 mm cutting and bending tester (jIRBT-210, Juniltech) mounted on the 1 after undergoing flexing of hopeless and, flexible substrate corresponding advertisement based on the shown list evaluated as typical for inserted crack, described to result to the computer of the table 2.

< Evaluation criteria >

○: crack american occurrence

Δ: of micro cracks in generating

X: film touch sensor rupture

(2) transmittance evaluation

In the embodiment and comparison the first deoxygenator the post cure applied over the glass protective layer after a visible-light transmittance haze measuring equipment (hM-150, Murasaki yarn) as measured by corresponding advertisement based on the shown list, described to result to the computer of the table 2.

Said table 2 refers to surface, film a touch sensor in the embodiment 1 to 6 having improved strength excellent Zn and flex, and at the same time having the electrodes play in. capable of confirming the.

Just, of nanoparticles in the embodiment 6 in the case of a dimensioned to be slightly larger particle diameter, different transmittance been lowering slightly than in the embodiment, a excess slightly content of nanoparticles in the case of in the embodiment 4, different transmittance been lowering slightly than in the embodiment, aggregation of the nanoparticles strength is slightly a reduction in the inner pressure of was capable of confirming the.

While, compared e.g. film touch sensor 1 to 3 completely off or meting of bending evaluation in, crack corresponding advertisement based on the shown list size, the height, it is confirmed that ground to transmittance in addition in the embodiment can be.

(3) labelling evaluation

Number 1 in the embodiment 1 and comparison example 1 of integrated in on a protective film forming ITO layer thickness 0. 05 micro m 230 in convection oven ohmic metal layer so that the road 20 minutes annealing observing the corresponding advertisement based on the shown embodiment, the comparison was also Image e.g. shown in 5.

Also 5 reference to an surface, in the case of the present invention according to in the embodiment 1, having wrinkles, a diffusion prevention film comprising a thermal expansion properties excellent was capable of confirming the. However, compared e.g. in the case of 1, number 1 of the consensus pattern and the electrode protective layer based on variations in thermal expansion rate of ITO, surface between the load station and corrugations can be of confirming the.
