Yet, in the invention of patent documentation 1 and patent documentation 2 records, because therefore the glass substrate of the film of use PET etc. or abrading glass etc. can be created in the such defective of reverse seal of adhering to printing ink on the planarizing unit as the planarizing unit of printing ink overlay film.
In addition, in the invention of patent documentation 3 records, though by utilizing separating film to cover printing ink overlay film integral body, and across silicon rubber with air pressurize (with reference to Fig. 1 of the document), thus printing ink overlay film surface is applied uniform pressure, yet owing to exert pressure with face, therefore be difficult to the gap that landfill produces between separating film and printing ink overlay film, thereby have the defective that can't obtain the planarization effect fully by pressurization in printing ink overlay film integral body.
In addition, in the invention of patent documentation 4～6 records, as planarizing unit, use has: with blanket cylinder (patent documentation 4); Silicon chips etc. have covered the roller with suitable hardness (patent documentation 5) on surface; Surface-coated the metallic roll (patent documentation 6) etc. of the lower non-tackiness material of the surface energy of polyflon etc.Therefore, though can suppress printing ink to the reverse of planarizing unit seal, and carry out planarization, alleviate the such technical matters of irregular colour of color filter integral body for solution, its effect is still insufficient.
In addition, in recent years, display panels is not only maximization but also to the high precision int development, therefore strong hope suppresses the irregular colour of color filter effectively.
Summary of the invention
Therefore, the objective of the invention is to: provide a kind of being used for to be formed on the planarizing unit of the flattening surface of the printing ink overlay film on the transparency carrier, a kind of reverse seal that prevents printing ink promptly is provided, and can be suppressed at seeing through of above-mentioned transparency carrier produces irregular colour in the light printing ink overlay film planarizing unit and printing ink overlay film planarization roller.
To achieve these goals, printing ink overlay film planarizing unit of the present invention, it is the surface that presses on the coloring printing ink overlay film that is formed on the transparency carrier, and make the planarizing unit that has an even surface of above-mentioned printing ink overlay film, it is characterized in that: possess: have flexible substrate layer, be laminated in the release layer of above-mentioned substrate layer one side surface and be laminated in the elastic layer on above-mentioned substrate layer opposite side surface, the arithmetic average roughness (R on the surface of a side opposite of above-mentioned release layer with above-mentioned substrate layer side
a) be 30～280nm, and limitation table surface tension (γ
c) be below the 30mN/m.
In addition, be preferably, the thickness of above-mentioned elastic layer is 100～5000 μ m, and elasticity of compression rate (E

With reference to Fig. 1, the printing ink overlay film possesses with planarizing unit 1: substrate layer 2, coincide with substrate layer 2 one side surfaces 3 release layer 4, coincide with the elastic layer 6 of substrate layer another side 5.
In addition, it is flexible to require substrate layer 2 to have.Because it is flexible that substrate layer 2 has, therefore can avoid the printing ink overlay film with planarizing unit 1, with printing surface contacting under flat state, can prevent between the printing ink overlay film is with planarizing unit 1 and printing ink overlay film, to produce the gap as the planarization object.And, owing to possess and have flexible substrate layer 2, for example, the printing ink overlay film can be wound on the outer peripheral face of cylinder with planarizing unit 1, formation roller shape and using.
In addition, because substrate layer 2 is supporting substrates of release layer 4,, and require to have suitable physical strength and to the good stickability of release layer 4 therefore for the damage that prevents release layer 4 with peel off.
The surfaceness of substrate layer 2 can suitably be set according to material, thickness and the release layer 4 desired surfacenesses etc. of release layer 4.Therefore, though the surfaceness of substrate layer 2 is not limited to this, yet with arithmetic average roughness R
aExpression is preferably 20～500nm.Arithmetic average roughness R when substrate layer 2
aWhen being lower than above-mentioned scope, then the surfaceness of release layer 4 may be lower than the numerical value of expectation.Otherwise, as the arithmetic average roughness R of substrate layer 2
aWhen being higher than above-mentioned scope, then the surfaceness of release layer 4 became thick.And in order to reduce the thickness of the just necessary thickening release layer 4 of surfaceness.
The thickness of substrate layer 2, flexible, the physical strength etc. of considering substrate layer 2 is suitably set and is got final product, though particular determination not, be preferably 50～500 μ m, 80～200 μ m more preferably.When the thickness of substrate layer 2 is lower than above-mentioned scope, then be difficult to handle.In addition, also physical strength might can't be guaranteed.Otherwise, when the thickness of substrate layer 2 is higher than above-mentioned scope, then might damage flexible.
As the formation material of release layer 4, can enumerate: for example the silicon class release agent that forms by silicon rubber, silicon elastic-like material, silicones etc., for example fluorine class release agent that forms by fluororubber, fluorine elastic-like material, fluororesin etc. etc.They are surface free energy (limitation table surface tension) materials with smaller, therefore printing ink are had superior release property.The material of release layer 4 especially preferably uses the silicon class release agent in the above-mentioned material, more preferably silicones.
The surfaceness of release layer 4 is with arithmetic average roughness R
aBe expressed as 30～280nm, be preferably 50～250nm.Arithmetic average roughness R when release layer 4
aWhen being in the above-mentioned scope, for example, with the candy strip planarization of the painted filtering layer of three looks in the color filter time, can form trickle concavo-convex on the surface of printing ink overlay film, and in the planarization of printing ink overlay film, can suppress the generation of the irregular colour of color filter.
The surface tension of release layer 4 can consider that the release property of 4 pairs of printing ink overlay films of release layer is set.Particularly, as the limitation table surface tension γ of release layer 4
c, below 30mN/m, be preferably 10～25mN/m.As limitation table surface tension γ
cWhen being higher than above-mentioned scope, then when planarization, produce the reverse seal that printing ink is attached to release layer 4.Limitation table surface tension γ

The spring rate of elastic body 6 can be abundant at resiliency, and suitably select in the scope that degree of the compressed distortion can be not excessive.Particularly, the elasticity of compression rate E of elastic body 6
cBe 0.5～20MPa, be preferably 1～10MPa, as the elasticity of compression rate E of elastic body 6
cWhen being lower than above-mentioned scope, then too small to printing ink overlay film applied pressure when planarization, thus can't bring into play the effect of planarization fully.Otherwise, as the elasticity of compression rate E of elastic body 6
cWhen being higher than above-mentioned scope, then can't absorbing the projection that causes because of the foreign matter that is attached to elastic body 6 surfaces, thereby when planarization, produce concavo-convex on the surface of printing ink overlay film.
