The making of mould release membrance
By the coating agent of embodiment 1 commercially available polyethylene terephthalate film (trade name Le ミ ラ ー T60,50 μm
It is thick) on coat, it is 1 μm to make dried painting thickness, is dried 1 minute at 120 DEG C, has what is formed by the coating agent so as to make
The mould release membrance of cured film.For embodiment 10, dry 10 minutes at 120 DEG C, consolidated so as to make to have by what the coating agent was formed
Change the mould release membrance of film；For other embodiments and the coating agent of comparative example, operation similarly to Example 1 makes mould release membrance.
The solvent resistance of cured film
By the mould release membrance relevant with embodiment 1 after 23 DEG C are placed a night, the cotton by the cured film using impregnation MEK
When rod is embrocated, reciprocal even more than 100 times, cured film does not also dissolve.On the other hand, pair relevant with embodiment 9 release
When film is equally evaluated, at the 80th time, base material film exposes.Equally grasped for the mould release membrance relevant with other embodiments
Judge solvent resistance, however, reciprocal even more than 100 times, cured film does not also dissolve.On the other hand, pair with comparative example 1
When relevant mould release membrance is equally evaluated, at the 2nd time, base material film exposes.On the other hand, for relevant with comparative example 2
Film, reciprocal even more than 100 times, cured film does not also dissolve.As a result it is shown in table 2.
The evaluation of release
After the mould release membrance relevant with embodiment 1 is placed into a night, on its cured film surface, by polyester tape (Japanese day east
Electrician's (strain) 31B adhesive tapes processed：20mm is wide) it is bonded while being crimped using 2kg roller, placed 1 hour at 23 DEG C.
Then, will be foregoing using テ Application シ ロ Application universal testing machine (ProductName RTC-1250A, Japan (strain) オ リ エ Application テ ッ Network systems)
Adhesive tape is stretched (0.3m/min) in the horizontal direction with 180 ° of angle, and required power (N/20mm) is peeled off in measurement.Meanwhile
Similarly operated for the mould release membrance of other embodiments and comparative example, measure peeling force.It is relevant with comparative example 1 release evaluating
During film, it can not be measured because cured film aggegation destroys.As a result it is shown in table 2.
