(3) coating of active energy ray curable adhesive composition
The coating method of active energy ray curable adhesive composition is applied to seperation film 10 using applying device 50 There is no particular restriction, for example, can use slot die mould (slot die) method, reverse gravure coating process, micro- intagliotype, dipping Method, rolling method, flexible printing method etc..The thickness of overlay 11 comprising active energy ray curable adhesive composition so that The thickness of the adhesive phase 12 of seperation film 20 with adhesive phase reaches the mode of scope described later to adjust.
As shown in figure 1, more specifically, working procedure of coating can be the separation in the strip continuously rolled out from the 1st releasing roller 1 The process of one face continuously coating active energy ray curable adhesive composition of film 10.Now, as shown in figure 1, can be with side Seperation film 10 is wound in the side coating active energy ray curable adhesive composition of painting application roller 60.
[exposure process]
This process is following process：The seperation film 15 with overlay 11 is continuously transported on side, while being irradiated to the overlay 11 Active energy beam, so as to implement pattern exposure, obtains (the reference picture of seperation film 20 with adhesive phase with adhesive phase 12 1 and Fig. 3).By this process, it is continuously manufactured by the intermediate of the optical component with seperation film, there is the band of adhesive phase 12 The seperation film 20 of adhesive phase.Active energy beam is preferably ultraviolet.
The 1st exposed region is formed on adhesive phase 12 using based on the pattern exposure that active energy beam irradiates The 12a and light exposure 2nd region 12b (Fig. 3) smaller than the 1st region 12a.2nd region 12b can be unexposed region, but excellent Elect as in the case where making light exposure be less than the 1st region 12a limit through exposing and having carried out to a certain extent to a certain extent based on work The region of the curing reaction of performance amount radiation exposure.
The 1st region 12a and the 2nd region 12b of adhesive phase 12 configuration pattern can be according to the Flexible Displays applied The bending shape of device is selected.The example of the bending shape of flexible display is as shown in Figure 4.Fig. 4 (a) can be wound Flexible display, Fig. 4 (b) is the flexible display that can be folded.
As shown in figure 1, the adhesive phase 12 comprising the 1st region 12a and the 2nd region 12b can be utilized across 81 pairs of mask The irradiation of overlay 11 comes from the method for the active energy beam of exposure device (active energy beam irradiation unit) 80 to be formed. The irradiation of active energy beam repeatedly to overlay 11 can be carried out.By the slit shape for suitably selecting used mask 81 Shape, characteristic, across illuminating method of active energy beam of mask 81 etc., can matching somebody with somebody the 1st region 12a and the 2nd region 12b Placing graphic pattern is formed as required pattern.If the configuration pattern to the 1st region 12a and the 2nd region 12b, the activity across mask 81 Illuminating method of energy-ray etc. shows concrete example, then exemplified by as shown below.
A) Fig. 5 irradiates the diagrammatic top of the state of active energy beam for expression across shadow mask 81a to overlay 11 Figure.Arrow represents the carriage direction of the seperation film 15 with overlay 11.Shadow mask 81a has along with overlay 11 Seperation film 15 length direction (carriage direction) direction on multiple slits (through-Penetration portion) 85 for extending, these multiple slits 85 Arranged along film width.Exposure device (active energy beam irradiation unit) 80 is fixed relative to shadow mask 81a. If irradiating the active energy beam from exposure device 80 to the seperation film 15 with overlay 11 across shadow mask 81a, The 1st region 12a and the 2nd region 12b adhesive phase 12 can be obtained for example being configured with as Fig. 6 (a).The configuration pattern pair It is favourable in the flexible display that can be wound as shown in Fig. 4 (a), by alternately configuring as shown in Fig. 6 (a), With the 1st region 12a and the 2nd region 12b extended in coiling direction generally perpendicular direction, so as to relax during winding should Power, it is possible thereby to maintain the adaptation between adhesive phase 12 and the component being adjacent well.
If b) other parts to be all made to the mask 81 of through-Penetration portion (slit) using reservation width central portion, The 1st region 12a and the 2nd region 12b adhesive phase 12 can be obtained for example being configured with as Fig. 6 (b).The configuration pattern pair It is favourable in the flexible display that can be folded shown in Fig. 4 (b), by setting the 2nd region in position corresponding with folding part 12b, so as to relax stress during folding, it is possible thereby to maintain well between adhesive phase 12 and the component being adjacent Adaptation.
If c) irradiating 1 active-energy using the shadow mask with slit as mask 81a as shown in Figure 5 to penetrate Line, the then region being blocked turns into the 2nd region 12b for not being exposed (light exposure is zero).On the other hand, if as shown in fig. 7, adopting Used in across with slit 85 shadow mask 81a irradiation active energy beam after (Fig. 7 (a)), not across mask and to coating (Fig. 7 (b)) multiple irradiation of the whole face irradiation active energy beam of layer 11, then it is exposed area that can make the 2nd region 12b Domain.The order of Fig. 7 (b) process and Fig. 7 (a) process can also be overturned.
If d) as shown in figure 8, irradiating active energy beam across half-tone mask 81b, can be formed using 1 irradiation The 2nd exposed region 12b.Half-tone mask 81b refer to the larger region 82 of the transit dose of active energy-ray and compared with The mask in small (being not zero) region 83.
E) another example of 1st region 12a and the 2nd region 12b configuration pattern is shown in Fig. 9~Figure 12.1st region 12a And the 2nd the directions of region 12b extensions can be with the carriage direction of film (or when the optical component 40 of seperation film is made into monolithic body Such as short side direction) parallel (Fig. 9).
There is no particular restriction for 1st region 12a and the 2nd region 12b width, these regions exist it is multiple in the case of, Can be with mutually the same (Figure 10 (a)), can also difference (Figure 10 (b)).1st region 12a is shared by the surface of adhesive phase 12 Also there is no particular restriction for ratio, and the distance (spacing) between the 1st adjacent region 12a can shorten (Figure 11 (a)), can also increase (Figure 11 (b)).In addition, as shown in figure 12, the 1st region 12a and/or the 2nd region 12b light exposure can along some direction by Gradually change.If with such a gradual change, the adhesive phase on the 1st region 12a and the 2nd region 12b border can be reduced The change (poor) of 12 storage modulus, it is possible thereby to improve the durability in the adhesive phase 12 in knee.Light exposure gradually becomes The 1st region 12a and/or the 2nd region 12b changed can be formed by irradiating active energy beam across gradual change mask.Gradual change The mask that mask gradually changes for the transit dose of active energy beam along some direction.
The light source of the active energy beam irradiated to overlay 11 is not particularly limited, but preferably in below wavelength 400nm Ultraviolet with luminous distribution, specifically, can use low pressure mercury lamp, medium pressure mercury lamp, high-pressure sodium lamp, ultrahigh pressure mercury lamp, Chemical lamp, black light lamp, microwave-excited mercury lamp, metal halide lamp, LED type ultraviolet lamp etc..
Exposure intensity to the active energy beam of overlay 11 is, for example, 1~1000mW/cm2.In addition, strong with light irradiation The product of degree and light irradiation time are, for example, 10~5000mJ/cm come the accumulated light represented2。
