Degree of polarization or monomer transmissivity be given range.In one embodiment, dip time is set, so as to obtain
The degree of polarization of polarizing coating is 99.98% or more.In another embodiment, dip time is set, so as to obtain
The monomer transmissivity of polarizing coating is 40%~44%.
(stretch processing)
Any suitable method can be used in the drawing process of laminated body.Specifically, can be fixing end stretch (for example,
Use the method for tentering stretching-machine), can also be free end stretch (for example, make laminated body pass through the different roller of peripheral speed it
Between and the method that carries out simple tension).Furthermore it is possible to be that synchronous bidirectional stretches (for example, using the side of synchronous bidirectional stretching-machine
Method), can also be gradually biaxial tension.The stretching of laminated body can a step carry out, can also multistep carry out.When multistep carries out,
The stretching ratio (maximum tension multiplying power) of aftermentioned laminated body is the product of the stretching ratio of each step.
Stretch processing can be stretching mode in making laminated body be impregnated in stretch bath and the water that carries out, can also be gas atmosphere
Enclose middle stretching mode.In one embodiment, at least implement stretch processing in 1 water, preferably by stretch processing in water and gas
Stretch processing is combined in body atmosphere.It, can be in the glass transition than above-mentioned resin base material, PVA resinoid layers by being stretched in water
It is stretched at temperature (representative is 80 DEG C or so) lower temperature, PVA resinoid layers can be inhibited to crystallize, and can be by it
High magnification stretches.As a result, the polarizing coating with excellent polarization characteristic can be manufactured.
As the draw direction of laminated body, any suitable direction may be selected.In one embodiment, along strip layer
The length direction of stack is stretched.It is its conveying direction (MD) specifically, laminated body is conveyed along its length.Another
In one embodiment, the width direction along strip laminated body is stretched.Specifically, laminated body is defeated along its length
It send, is the direction (TD) vertical with its conveying direction (MD).
The draft temperature of laminated body can be set to any suitable according to forming material, the stretching mode etc. of resin base material
Value.Using stretching mode in atmosphere, draft temperature is preferably the glass transition temperature of resin base material

On the other hand, the draft temperature of laminated body is preferably 170 DEG C or less.By being stretched at such temperatures, can inhibit
The crystallization of PVA resinoids is fast-developing, and the unfavorable condition caused by the crystallization can be inhibited (for example, interfering due to stretching
The orientation of caused PVA resinoids layer).
When using stretching mode in water as stretching mode, the fluid temperature of stretch bath is preferably 40 DEG C~85 DEG C, more
Preferably 50 DEG C~85 DEG C.As long as being such temperature, so that it may to inhibit PVA resinoid layers to dissolve, and can be with high magnification
It is stretched.Specifically, as noted previously, as relationship with the formation of PVA resinoid layers, the glass transition of resin base material
Temperature (Tg) is preferably 60 DEG C or more.In this case, when draft temperature is less than 40 DEG C, even if in view of the tree carried out using water
The plasticising of aliphatic radical material, there is also the hidden danger that can not be stretched well.On the other hand, the temperature of stretch bath is higher, PVA class trees
The dissolubility of lipid layer is higher, there is the hidden danger that can not obtain excellent polarization characteristic.
When using stretching mode in water, so that laminated body is impregnated in boric acid aqueous solution and stretched (in boric acid water
It stretches).By using boric acid aqueous solution as stretch bath, the tension applied when can assign resistance to Tensile to PVA resinoid layers
Rigidity and be not dissolved in the water resistance of water.Specifically, boric acid can generate tetrahydroxy borate anion in aqueous solution, and
