It can be seen from the above description that the above embodiments of the present invention realized the following chievements:
From the data in embodiment it is found that using composition provided by the invention, use cationic curing composition can be with
Pressure-sensitive adhesive layer surface formed it is good sprawl, and can quickly remove pressure sensitive adhesive glue-line, reach visbreaking effect.And from comparative example
Data it is found that using radical UV curing system, technique is required high, and cost input is big.Meanwhile radically curing composition
Spreadability is poor, can not be attached to pressure-sensitive adhesive layer surface, and whole visbreaking can not be accordingly carried out to pressure-sensitive adhesive layer.Group in comparative example 2
Object is closed although can sprawl on pressure sensitive adhesive, because that can not adhere to, can not equally play the role of visbreaking.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
