Abstract

PROBLEM TO BE SOLVED: To provide a transfer material, for preventing foil burrs from falling away, by which a neatly molded product free from fallen-away fragments of foil burrs and without dents can be manufactured during continuous transfer processing. SOLUTION: This transfer material has a transfer layer formed on a base sheet having release properties. The transfer layer is tested by the test method that a test load of 5 to 1,000 mN is forcibly applied into the surface of the transfer layer, then maintained as it is and removed to break away a triangular spindle indenting tool from the transfer layer, using the triangular spindle indenting tool made of a diamond with an interarris angle of 100 to 117 deg. at an environment temperature of 20 deg.C and a velocity of 0.005 mm/s. When the plastic deformation value of the obtained transfer layer is given as x1 and the elastic deformation value of the transfer layer as x2 , the transfer layer shows an established relationship of 0.05<=x1 /x2 <=10.

The plastic deformation value and the elastic deformation value are within the specified numerical ranges.
The material of the transfer layer 6 is selected so that The transfer material for preventing the burr from falling off according to the present invention is constructed.
Transfer layer 6 is formed by a transfer roll 7 or the like in a transfer method.
Pressing (see Fig. 5) and mold clamping in simultaneous molding transfer method
(See Fig. 6)
So that the non-transferred portion is
Resilient so that no debris from the foil 12
It has deformability, and the peeling of the base sheet
The boundary between the transfer portion and the non-transfer portion or the foil burr 12 occurs.
In the case where
It must also have sexual deformability. However, such an article
Even if you select a material that meets the requirements,
Depending on the condition, that is, storage temperature, storage humidity, etc.
Marks may or may not have formed. Cause
If the transfer layer is made of a curable material,
It is considered that the material was altered and became hard and brittle. However,
It is difficult to keep all storage conditions constant, and in appearance
Since there is no difference and sorting cannot be performed,
A large number of good products were generated. Therefore, a triangle having a tip shape as shown in FIG.
Attach the weight indenter 13 and push the transfer layer 6 to deform it.
And then unload the mechanism (see Fig. 1)
Is used to calculate the deformation value-load curve data as shown in FIG.
And then the plastic deformation value x ₁And elastic deformation value x₂Total
Whether or not the foil burr 12 will fall off
Is determined before performing the transfer processing. To obtain the plastic deformation value and the elastic deformation value,
Specifically, this is performed as follows. That is, a commercial tensile

3 by removing the transfer layer from the transfer layer.
Can be Here, the reason why the environmental temperature is set to 20.degree.
Processing is often carried out in a normal room temperature atmosphere.
It is unlikely that the temperature will be significantly different from 0 ° C.
You. In the transfer process, heating is performed, but instantaneous
It is. The mechanism of bonding the transfer material 1 is as follows.
The layer is heated and softened and melted to become tacky, then cooled and solidified.
The adhesive material comes out when it is made
When stripping off, it is almost at room temperature. Also,
If a considerable amount of heat remains after bonding,
Leave it for a while to obtain adhesive properties, then peel it off and immediately
Do not peel off the transfer material on the seat. A diamond having an angle between ridges of 100 to 117 °
Using a triangular pyramid indenter made of Mondo
By pushing the load to one point,
This is because the accuracy of the test can be improved. The ridge
The angle between 100 and 117 ° is the angle α between the edges of the tip of the indenter,
β and γ have a relationship of 100 ° ≦ α = β = γ ≦ 117 °
(See FIG. 3). Further, the test load is applied at a speed of 0.005 mm / s.
The weight is applied to the range where reproducible data can be obtained
And pursued conditions that can be measured as quickly as possible.
At this time, a speed of 0.005 mm / s was obtained. The test load is limited to 5 to 1000 mN.
The reason is as follows. First, the plastic deformation value is finally 0.01 μm.
m to 0.1 mm. Data positive
Accuracy is better if you push in as deeply as possible
You. However, since the plastic deformation value itself becomes large,
If there is a plastic deformation mark exceeding 0.1 mm even if
0.1 mm at most
You only need to measure it. On the other hand, the plastic deformation value becomes 0.01 μm
If not, the measurement error will increase and the accuracy of the data will increase.
Is considerably lower. That is, a test load exceeding 1000 mN
And finally the plastic deformation value does not reach 0.01 μm.
When examining a good transfer layer, the surface does not deform very hard
Or almost elastic like rubber
In this case, the transfer layer is made of such a material.
I couldn't find it. When the test load is less than 5 mN,
Investigate the transfer layer whose plastic deformation value exceeds 0.1mm
And the surface is quite easy to dent,
If it is a material, after transfer, the abrasion resistance required for the transfer layer,
There was no resistance such as chemical resistance. Therefore, the test load is 5 to 1000 mN
It suffices if it is done in the range of. In the present invention, 0.05 ≦ x
