Other additives: (methyl) acrylic ester monomer 0.8 % by weight, acetone, 2,4,6-trimethylbenzoic acid, 1-spicy thioalcohol, diphenylphosphine are (although these compounds observe the peak in gas chromatographic analysis, below quantitation limit.）
The mensuration of＜contact angle 〉
Drip as the surface of the membranaceous optics of determination object the commentary valency of going forward with bonding agent 5ml after, placed 5 minutes, then, the Contact Angle System " OCA30L " that produces with DataPhysics company has measured the contact angle of this optics and this evaluation use bonding agent.
The mensuration of＜the maximum shear stress 〉
After the aforementioned evaluation of the surface-coated that is fitted in advance the optics on glass plate is with bonding agent, then glass plate is overlapped on the surface that has been coated with bonding agent.At this, make the length of bonding agent coated film of the direction of stress application be about 12.5mm, the thickness of bonding agent coated film is adjusted into approximately 150 μ m.
Then, use UV irradiation unit (Shinko chemical company product), with accumulated light 5000mJ/cm
2Carry out the ultraviolet ray irradiation, the aforementioned adhesion agent is solidified, form adhesive phase.
To the mensuration sample of making like this, the Autograph(AG-1 that uses company of Shimadzu Seisakusho Ltd. to produce) make on direction relative between glass plate, namely on the direction of pulling open adhesive phase from optics with certain speed (5mm/min) stress application, obtain the maximum shear stress.
The evaluation that＜bubble occurs 〉
To having or not bubble to carry out following evaluation between optics and transparency protected parts.
At first, use glass plate as transparency protected parts.Then, aforementioned evaluation is acted on the bonding agent conversion bonding agent that forms the adhesive phase between between optics and transparency protected parts.
Particularly, after the surperficial central portion coating adhesive of the optics of indulging 9cm * horizontal 9cm, glass plate is overlapped on it, estimate the expansion situation of bonding agent.Do not launch good to be designated as zero with entraining into bubble, bonding agent, with being designated as of entraining into that part bubble, bonding agent well do not launch *.If do not entrain into bubble, bonding agent and launch well overlapping the glass plate stage, even be cured processing, also still have good outward appearance, and if entrain into bubble, even be cured processing, bubble still can be residual, bad order.

Table 1
Embodiment and comparative example
Sample No.3 has been carried out aforementioned bubble estimated, consequently, do not entrained into bubble, bonding agent launches good.On the other hand, sample No.9 has also been carried out aforementioned bubble estimated, consequently, entrained into the part bubble, bonding agent does not launch well.
＜sample estimates 2 〉
It is that 25 °, the maximum shear stress are that the adhesion promotion of 160N is processed that the surface of PET base material film can make contact angle.
Estimate if aforementioned optics is carried out aforementioned bubble, it is expected to not entrain into bubble, bonding agent launches good.
Reference example
The maximum shear stress of TAC base material film is 55N.
