剤につき種々研究の結果、本発明に到達した。Conventionally, for example, when manufacturing household electrical appliances, etc., on the assembly line, adhesive is applied to the required parts of the parts necessary for assembly, and the parts are temporarily fixed and covers are temporarily attached. It is desired that the adhesive be turned into an adhesive instantly. Solvent-based adhesives are available as such adhesives, but those that generate organic solvents cannot be used in production lines. Furthermore, emulsion-based adhesives have thixotropic properties and have the advantage of being able to be applied to desired areas by screen printing, but since they are water-based emulsions, they require a lot of time to dry, making them unusable. In recent years, there have been ionizing radiation-curable adhesives that can be turned into adhesives in a short period of time, such as when irradiated with ionizing radiation for a few seconds, but none of them have properties suitable for screen printing, i.e., no stringiness, and they cannot be used in the required parts of the parts. It is difficult to use as an adhesive when applied only to surfaces. The inventors have arrived at the present invention as a result of various studies on ionizing radiation-curable adhesives that can be applied by screen printing.

Generally, the emulsion resin is a fine powder with a particle size of less than about 1/μ, and can be suitably used. Also usable are polyurethane acrylate resins, soft vinyl chloride resins, etc., which are made into fine powders of a predetermined particle size by freeze-pulverization or the like. If a resin fine powder that has the property of swelling with an ionizing radiation-curable adhesive component is used, the adhesive component absorbed by the resin fine powder and the adhesive component outside the resin fine powder are connected to each other. The fine resin powder in the curable pressure-sensitive adhesive containing the fine resin powder after curing can be more stably held.

Next, we recognized the separated adhesive fine particles 3-Of-hydroxyethyl acrylate sot and 2-ethylhexyl acrylate-11-01.
and stirred to make a homogeneous mixture, which was left overnight to swell the adhesive particles with the acrylic monomer, and stirred to uniformly disperse the particles. A screen printing pressure-sensitive adhesive of the present invention was obtained which was in the form of a colorless and transparent paste without any stringiness as a whole. The paste-like adhesive thus obtained was coated on a polyester film having a thickness of 2 .mu.m by a screen printing method using 200 meshes of gold copper in a conventional manner. There was no stringing at all, and the wire mesh ran very well. In addition, this adhesive could be easily applied partially (bang coating). The paste-like sticky polyester film obtained by screen printing as described above was cured by irradiation with jMrad electron beam in a nitrogen stream, and the following adhesive properties (adhesive force, probe tack, ball tack) was obtained.

The above-mentioned raw materials were mixed well, and the fine powder of polyurethane resin was uniformly dispersed; the screen printing pressure-sensitive adhesive of the present invention was obtained. Using the obtained adhesive, the same screen printing apparatus as in Example 2 was used to coat the surface of a polyester film with a thickness of 2 μm (layer thickness of 230 μm). There were no problems in the coating process.

Saeh Pole Tack // Example: Methanol is added to a non-adhesive acrylic emulsion (Nipole, Nippon Zeon Co., Ltd. trade name) for salting out, and microparticles (microparticles smaller than /μ obtained by emulsion polymerization) are agglomerated. A small lump of material was obtained. The resulting nodules were 30? 700 parts of butyl acrylate-vinyl acetate copolymer (molecular weight/10,000) and isooctyl acrylate were added to the above-mentioned curable adhesive, left overnight, and then stirred to make the whole mixture uniform. A paste-like adhesive of the present invention was obtained. The obtained paste-like adhesive was applied to the surface of a 23μ polyester film using a screen printing device to a layer thickness of 2Jμ, and the polyester film was irradiated with the same electron beam as in Example 3 to obtain a pressure-sensitive adhesive sheet. The characteristics of this adhesive sheet were as follows.
