A material coated with a release agent such as a fluorine compound or a fluorine compound is used. As the adhesive, various types of adhesives such as rubber-based, acrylic-based, vinyl ether-based emulsions, and solvent or solvent-free adhesives are used.

After drying, it is manufactured by bonding the surface base material together. For example, an acrylic copolymer resin is dissolved in a solvent such as toluene or ethyl acetate, or an emulsion is prepared, and various auxiliaries are added as necessary. It is manufactured by a method in which a pressure-sensitive adhesive layer is formed by blending an agent, coating it on a release base material, drying it, and then laminating a surface base material thereon to transfer the pressure-sensitive adhesive onto the surface base material.

Since increasing production speed is highly desirable from the standpoint of operational efficiency, attempts are often made to increase the dryer temperature during the drying process.

儀なくされているのが実情である。However, when the temperature of the dryer is raised, the moisture evaporates rapidly, which tends to cause blisters to form on paper and the adhesive layer.
Moreover, printing on an adhesive sheet with blisters results in uneven printing, so in reality, the process is forced to operate at low speeds.

A release agent layer is used which is coated in a range of about 5 to 3 g/nr and is cured by heat curing, ionizing radiation, or the like.
而して、本発明の方法では前述の如く、粘着剤層の乾燥
手段として近赤外線を使用するところに極めて重大な特
徴を存するものである。As mentioned above, the method of the present invention has an extremely important feature in that near-infrared rays are used as a means for drying the adhesive layer.
従来から、粘着剤層を乾燥する方法としては、蒸気加熱
、熱風加熱、ガスヒーター、電気ヒータ、赤外線ヒータ
ー、高周波、レーザー、電子線等の各種加熱方式が使用
されており、赤外線乾燥もよく知られている。Conventionally, various heating methods such as steam heating, hot air heating, gas heater, electric heater, infrared heater, high frequency, laser, and electron beam have been used to dry the adhesive layer, and infrared drying is also well known. It is being

学同人／１９７９年４月２０日発行参照）が、従来から
使用されている赤外線乾燥機では、波長が２．５μｍ以
上の中間赤外領域や遠赤外領域の赤外線が専ら使用され
ており、本発明で使用するような近赤外領域の赤外線乾
燥は比較的新しい乾燥方式である。In addition, infrared rays generally include near infrared rays with wavelengths of 0.75 to 2.5 μm, mid-infrared rays of 2.5 to 25 μm, and wavelengths of 25 to 200 μm.
It is broadly classified into far infrared rays with a wavelength of 0 μm (see Instrumental Analysis Tebiki Kagaku Dojin / published on April 20, 1979), but conventionally used infrared dryers are capable of producing far infrared rays with a wavelength of 2.5 μm or more. Infrared rays in the outer and far infrared regions are exclusively used, and infrared drying in the near infrared region as used in the present invention is a relatively new drying method.
本発明の方法では、この近赤外領域の赤外線を利用する
ものであり、波長が０．７５〜２．５μｍ、より好まし
くは１．０〜２．０μｍである近赤外線を使用するもの
である。The method of the present invention utilizes infrared rays in this near-infrared region, and uses near-infrared rays with a wavelength of 0.75 to 2.5 μm, more preferably 1.0 to 2.0 μm. .
波長が０．７５μｍより短くなると、粘着剤層の乾燥の
ための水分の蒸発に対する効果が極端に少なくなり、そ
の目的を達成することが出来ず、また波長が２．５μｍ
より長（なると、単なる水分の蒸発、乾燥には有効であ
るが、本発明の所望の効果を得ることは出来ない。If the wavelength is shorter than 0.75 μm, the effect on moisture evaporation for drying the adhesive layer will be extremely reduced, and the purpose cannot be achieved.
If the duration is longer, it is effective for mere evaporation of moisture and drying, but the desired effects of the present invention cannot be obtained.
近赤外線による乾燥によって、粘着剤層がブリスターを
発生することな（均一に乾燥される理由は明らかではな
いが、恐らく近赤外線は粘着剤層に対する透過力が強く
、且つエネルギー密度が高いために、高速での粘着シー
トの製造においても粘着剤層が瞬時に、しかも均一に乾
燥されるためではないかと推測される。By drying with near-infrared rays, the adhesive layer does not generate blisters (the reason why it dries uniformly is not clear, but it is probably because near-infrared rays have a strong penetrating power through the adhesive layer and a high energy density). It is speculated that this is because the adhesive layer dries instantly and uniformly even in the production of adhesive sheets at high speeds.
