In this way (for example), it will have the property of absorbing near infrared rays (which are heat rays) Films or coatings used in PDPs The required function. For example, the screen in near infrared & Qing or the like emits it and acts on a device near the PDP and uses the near red, the next remote control device, or the instrument, or is Some other electronic devices cause its wrong operation. Therefore, a near-infrared absorbing layer that can absorb near-infrared rays and pass visible light is formed to shield the near-infrared rays emitted from the screen. Such a film may be coated The layer is generally formed by '11 kinds of near-infrared absorbing resin compositions. In this pDps of 2, °, the PDPs are expected to lighten the weight of the PDPs and simplify the manufacturing process to save costs. So, in order to save costs For the purpose of reducing costs, research was conducted to reduce the number of layers in the front panel. At the same time, as for the conventional pressure-sensitive adhesive, 'there is already a cohesive group 200418949', it was revealed that it includes a subtraction Polymers, cross-linking co-catalysts, and further include volatile acids (see, for example, Japanese Patent No. 2002-241 732 (page 142)).

It is not a material that can be used to form pressure-sensitive adhesive layers in electronic equipment or devices, such as PDPs. In addition, these also have other problems ’when used in the formation of pressure-sensitive adhesives Lu and other electronic devices or devices in PDPs’ dyes will degrade and fade to maintain their near-infrared ray absorption time. x Therefore, a technology is needed to obtain the basic performance characteristics of PDPs and similar ones, and reduce the number of layers of the arrow ^^ panel to reduce costs. ο [Summary of the invention] Summary of the invention _ IF + goods cut, and wood The purpose of Ming is to provide a kind of money adhesive composition, in which the near-infrared absorbing dye is relatively less deteriorated and deteriorated by ultraviolet rays, and: used in Qicheng sensation agent layer and the like to be used to form even = Layers of similar materials are bonded together, which can make the electric core: the function of the individual layers in other panels is formed by _ 着 剂 " ^: In the-, it can absorb near infrared rays and ultraviolet rays, two : Has the function of adjusting color tone.歩 Study the inventor's research on the pressure-sensitive adhesive composition and learned that when the near-infrared absorbing dye is added various kinds of research, a kind of shoe-sensitizing agent including 10 200418949: and = The sound in the composition) :: The final composition is used to form the sticky coffee (pressure-sensitive adhesive agent / 一 4 # used to form the plasma display and its similar layered materials) At the beginning, it is possible Will reduce the stratification of plasma displays or the like, and achieve a reduction in weight and simplification of the manufacturing process. In addition, near-infrared absorbing dyes in electronic instruments or devices such as electrical appliances are subject to electron emission, etc. The emitted ultraviolet light is degraded, and is easily deteriorated in the pressure-sensitive adhesive polymer, which leads to a reduction in its near-infrared absorbing ability ', but they found that the use of ultraviolet absorbers and / or a hindered amine light stabilized Agent can avoid degradation caused by ultraviolet light: and improve the durability of near-infrared absorbing dyes' and pressure-sensitive adhesives used in electronic instruments or devices It is possible to maintain satisfactory near-infrared absorption capabilities, such as for Denso displays.

In this example, the ultraviolet reduction suppressing effect on the near-infrared absorbing dye (B) is significantly improved. Each of these necessary ingredients may include a single kind, or two kinds, or a plurality of kinds. In a preferred case, the composition further includes an antioxidant (E), and therefore, it is preferable to use a combination of an ultraviolet absorption state (C), the hindered amine light stabilizer (D), and an antioxidant ( E) By this, the effect of the present invention can be more satisfactory.

The pressure-sensitive adhesive polymer (A) pre-used in the practice of the present invention preferably has a glass transition temperature of 80 to 20 ° C, so it is a monomer component that forms a polymer compared to 200418949 (especially). So that the glass transition temperature of the polymerization: can fall into the above range. When the glass transition / plate temperature is lower than 80 C, the high-temperature cohesive strength tends to weaken, and when it exceeds -20 ° C, it does not show transitional adhesion at normal temperature. Regardless of 5I5 kinds of f-month conditions', good stickiness may not be achieved. The glass transition temperature Tg V can be easily calculated according to the formula provided below.

When Mw is less than 250,000, it will be difficult to improve its supporting force (cohesive strength), even when cross-linking, and it will reduce its removability, so it will also make it It is difficult to balance the various physical properties that conflict with each other. When it exceeds 2,00,00, the polymerization stability may become worse. More preferably, it is not less than 20 200418949 but not less than 400'000 but not more than 150,000.

When the acid value is too high, the near-infrared absorbing dye may be deteriorated, or the polymerization may misreact with the reactive ultraviolet absorber (c) or the hindered amine photo-regulating agent, and thus lose its viscosity. The base value of the hardener polymer u) is preferably not more than 10 mg KOH / g, more preferably more than 5 mg KOΗ / g, and more preferably not more than 25 邶 邶 / g. Higher hydroxyl values cause degradation of the near infrared absorbing dye. The base value is the number of milligrams of gas required to neutralize the hydroxyl-bonded acetic acid in the sample of acetic acid. It can be measured by the method described in the JIS-K_〇 predicate, or it can be based on a charge composition (charge c〇mp〇siti〇n) = different and different as its theory value. The acid value is the number of milligrams of potassium hydroxide required to neutralize the acid contained in a 1 gram sample, and its y is determined by the method described in the above, or by the charge composition (Charge comP0sition) is calculated for beauty. , 讦 、, the pressure-sensitive adhesive polymer (A) mentioned above is preferably used in an amount of not less than 3 weights but not more than 99.9% by weight, and its 21 200418949 is relative to _ A weight% adhesive composition.

When the dye is soluble in an organic solvent, it can be easily dissolved in the pressure-sensitive adhesive polymer (a), thereby facilitating the preparation of a coating agent. Conversely, when the solubility of the dye is poor, it becomes difficult to mix the dye with the pressure-sensitive adhesive polymer ⑴ because of the preparation of the A 'coating agent. As for the solubility in an organic solvent, it is appropriate to use a near-infrared absorbing dye having a solubility of not less than 0.01 in a 100% by weight organic solvent.
