State.
In addition, the first hard conating 12 and/or the second hard conating 22 are embedded with multiple particles 15 backwards to the surface of base material 11, with
Multiple raised 16 are formed on the surface of the first metal layer 14 and/or second metal layer 24.The particle diameter of particle 15 is the first hard conating
12 or second hard conating 22 the thickness of flat site 17 5% to 25%.Wherein, flat site 17 is the first hard conating 12 or the
Two hard conatings 22 are not provided with the region of particle 15.
Specifically, particle 15 can irregularly, can also preset rules (as equably) be distributed in the first hard conating 12
And/or second in hard conating 22.Particle 15 can be spheric granules, or unsetting particle.For spheric granules when, particle 15
Particle diameter be its diameter；During without amorphous particles, the particle diameter of particle 15 is equal to the arithmetic mean of instantaneous value of the size in its all directions.
Particle 15 is embedded at the surface of the first hard conating 12 and/or the second hard conating 22, is not contacted directly with base material 11.
Therefore, still can be in the first metal layer 14 and/or second metal layer 24 when the particle diameter of particle 15 is less than the thickness of flat site 17

Illustrated by taking the first hard conating 12 as an example：
Particle 15 protrudes from the surface of the first hard conating 12, so that the surface of the first hard conating 12 forms the area of evagination
Domain, and the region that the first hard conating 12 is not provided with particle 15 then forms flat site 17.Due to the first transparency conducting layer 13 and
One metal level 14 is cascading the surface with the first hard conating 12, therefore both surface configurations and the table of the first hard conating 12
Face shape is identical.Therefore, in the first metal layer 14 and 14 corresponding region of particle, multiple raised 16 can be formed.
Similarly, when containing particle 15 in the second hard conating 22, the surface of second metal layer 24 can also form multiple raised 16.
When using volume to volume technique (roll to roll process) to manufacture the transparent conductive film 10 of strip, by
The surface of the first metal layer 14 and/or second metal layer 24 is set to form multiple raised 16 in particle 15.Therefore, transparent lead is being crimped
During electric thin film 10, multiple raised 16 can make to form point contact between two neighboring metal level, so as to prevent its inter-adhesive, pressure
Connect.
Existing with the conducting film for preventing adhesion function, the thickness that the particle diameter of particle must be more than hard conating could be in metal
The surface of layer forms projection.Therefore, the particle size of particle is limited to the thickness of hard conating, can not further reduce.However,
Grain particle diameter is bigger, then the haze value increase of conductive film, light transmission rate reduce, and then influence the optical effect of conductive film.
And in transparent conductive film 10, because particle 15 is embedded at the first hard conating 12 and/or the second hard conating 22
Surface, and the particle diameter of particle 15 is the thickness of flat site 17 of the first hard conating 12 or the second hard conating 22 (being collectively referred to as hard conating below)
The 5% to 25% of degree, much smaller than the thickness of hard conating.Therefore, the particle diameter of particle 15 is not limited by hard coat layer thickness, particle 15
Particle diameter can further be reduced relative to the particle diameter of particle in existing resist blocking and that conducting film, so as to reduce haze value, lifting light it is saturating
Rate is crossed, finally improves optical effect.
In the present embodiment, the surface of the first hard conating 12 and the second hard conating 22 is embedded with particle 15, so that first
The surface of metal level 14 and second metal layer 24 is each formed with multiple raised 16.
That is, the two-sided of resulting transparent conducting film 10 is each formed with multiple raised 16.Therefore, crimping
During transparent conducting film 10, the point position that contact is put between adjacent two metal levels is increased, therefore the effect that its resist blocking and that, resistance to compression connect
Fruit is more preferable.
Referring to Fig. 3, in another embodiment, the surface of any of the first hard conating 12 and second hard conating 22 is embedding
Provided with particle 15, so that the surface of the first metal layer 14 or second metal layer 24 is formed with multiple raised 16.
That is, the resulting only one side of transparent conducting film 10 has projection 16.Resist blocking and that, resistance to compression can played
While connecing effect, moreover it is possible to avoid the shade of two layers of particle 15 from being overlapped mutually, further to mitigate mist degree, so as to lift transparent lead
The optical effect of electric thin film 10.
In the present embodiment, particle 15 is identical with the material of the first hard conating 12 and the second hard conating 22.
Because particle 15 is identical with the material of the first hard conating 12 and the second hard conating 22 (being collectively referred to as hard conating below), therefore its
Optical parametric is also identical.Therefore, in the linkage interface of particle 15 and hard conating, it is impacted smaller that light propagates institute, particle 15 with
It is an entirety that hard conating is closer.During when light through the first hard conating 12 and the second hard conating 22 containing particle 15, its
Distortion is smaller caused by round.Therefore, transparent conducting film 10 reach resist blocking and that, purpose that resistance to compression connects simultaneously, also
It is avoided that its optical property is adversely affected.
Further, in the present embodiment, the material of particle 15 is silica, organosilicon polymer, acrylic polymer
Compound or styrene polymer.
Above material has the advantage that translucency is good, is easily obtained, and can meet the premise of performance requirement for particle 15
Decline low cost.Certainly, also other suitable materials can be selected according to the performance and cost needs of reality.
In order to realize, more preferably resist blocking and that, resistance to compression connect effect and optical effect, have for the dense degree of projection 16
It is corresponding to require.
In the present embodiment, the first metal layer 14 and/or the surface of second metal layer 24, the distribution density of projection 16 is 100
~3000/mm2。
When the distribution density of projection 16 is excessive, it can cause that the haze value of transparent conducting film 10 is excessive, light transmission rate drop
It is low, and then have a strong impact on the outward appearance and optical effect of transparent conducting film 10.And if the distribution density of projection 16 is too small, then
The effect of resist blocking and that is limited.In above-mentioned roughness and density range, transparent conducting film 10 can preferably take into account resist blocking and that
And optical effect.
In addition, more preferably resist blocking and that, resistance to compression connect effect and optical effect in order to realize, for the first hard conating 12 i.e. the
The thickness of two hard conatings 22 and the height of projection 16 have corresponding requirement.
In the present embodiment, it is multiple on edge on the direction on the first metal layer 14 and/or the surface of second metal layer 24
The height of projection 16 is 0.1~0.5 μm.Further, in the present embodiment, the thickness of flat site 17 is 0.5~2 μm.
The height of projection 16, refer to that projection 16 protrudes from the height on the first metal layer 14 and/or the surface of second metal layer 24
Degree.Because the size of particle 15 is smaller, therefore it is difficult to be accurately controlled each raised 16 height.Therefore, by projection 16
Highly control is in above-mentioned altitude range.It is pointed out that in actual production, due to being difficult to each particle 15
Accurately controlled, therefore the height for having the projection 16 that few partial particulate 15 is formed being difficult to avoid that is located above range
Outside.But influenceed caused by part projection 16 negligible.Moreover, above-mentioned height also may refer in preset range
The arithmetic mean of instantaneous value of interior a number of raised 16 height.
In general, the height of projection 16 is higher, then resist blocking and that effect is better.But with the rise of height,
The size of grain 15 so as to cause the haze value of transparent conducting film 10 also to increase therewith, and reaches one mutually in requisition for increase
Determine will to have a strong impact on after degree the optical effect of transparent conducting film 10.And in above-mentioned altitude range, transparent conductivity
Film 10 can preferably take into account resist blocking and that and optical effect.
Wherein, the height of projection 16 can be changed by adjusting the insert depth of the size of particle 15 and particle 15.
Above-mentioned transparent conducting film 10, particle 15 form the first metal layer 14 and/or the surface of second metal layer 24
Multiple raised 16, so as to play a part of preventing adhesion.It is additionally, since particle 15 and is embedded at the first hard conating 12 and/or second
The surface of hard conating 22, and the particle diameter of particle 15 is the thickness of flat site 17 of the first hard conating 12 or the second hard conating 22
5% to 25%, much smaller than the thickness of hard conating.Therefore, it is above-mentioned transparent compared with traditional conducting film with the function that prevents adhesion
The particle diameter of particle is substantially reduced in conductive membrane 10.The particle diameter of particle 15 is smaller, and the effect of blocking to light is weaker.Therefore, may be used
