8l-81) 4 and polyester-based heat ray reflective film (Toshisha Lumisolar 38-EAI, 38
A photocrosslinking type EV with two types of functional films (μ thickness) 5
This is a laminate for a VDT filter in which 23 sheet-like adhesive films (EVA sheets A) are laminated and integrated as shown in the figure, and the method for making the same is as in Example 2.

れる。The functions of this filter include reducing externally reflected light with the anti-glare glass 6, adjusting visible light with a polarizing filter, improving contrast, cutting reflected light from inside the VDT, cutting ultraviolet rays, N with conductive film, magnetic shielding, and grounding. Various functions required for a VDT filter, such as preventing static electricity on the filter due to connections (reducing dust adhesion), etc., are achieved at a high level with a three-layer structure that has a total thickness of 3.

かえたものである。Note that Figure 1 shows a film-like filter that does not use any surface materials such as glass, but only functional films 1 and 3 and adhesive [2], and Figure 3 shows a filter that uses thermally crosslinkable EVA resin as an adhesive. An example in which layer 8 is used as an adhesive layer and transparent conductive glass 9 is used instead of a heat ray reflective film, FIG. 4 shows an example in which the glass on the operator side is removed and anti-glare hard coat treated polarizing film 10 is used as the surface material. This is an example in which a hard-coated polycarbonate plate 11 is used on the back side to reduce weight and simplify the structure.
The figure shows an example in which two of the CVA adhesive layers in FIG. 2 have been replaced with adhesives.

考えられる。In addition, when the degree of polarization as a filter was measured, a considerable decrease was observed, and eye fatigue was noticeable when a test was actually performed to attach the filter to a CRT. This is considered to be because the polarizing film deteriorated due to heat and the degree of polarization decreased.

In the filter of the comparative example, the reflected image appeared uneven, which was a concern for the user of the filter.
