2. Description of the Related Art A delayed tack-type pressure-sensitive adhesive composition for a delayed tack-type pressure-sensitive adhesive sheet comprises a solid plasticizer and a thermoplastic pressure-sensitive adhesive as essential components, and a mixture of these materials with a tackifier and the like. It can be obtained by coating materials. The pressure-sensitive adhesive layer surface of the delayed-tack-type pressure-sensitive adhesive sheet, that is, the delayed-tack-type pressure-sensitive adhesive composition does not show any tackiness at normal temperature, but the tackiness is manifested by heating, and for a while without heating. This is to maintain the inter-adhesion.

[0003] The delayed tack type adhesive sheet does not require the release paper used in the conventional tack sheet which does not exhibit delayed tack type adhesiveness, and has the advantage that unnecessary dust does not appear after pasting. Not only is it not bulky as an adhesive sheet without paper, but also if it is exposed to a heat source such as a heater or a hot air burner for a short time, it exhibits adhesiveness and can be used in the same manner as a conventional tack sheet. Furthermore, since it is possible to bond by applying heat after applying to the object to be stuck, an adhesion error can be prevented.

[0004] Even with the delayed tack type pressure-sensitive adhesive sheet having such advantages, there have been some problems in the conventional one. The first problem is blocking. Blocking is a phenomenon in which tackiness is exhibited despite unintended adhesion, and may be induced when exposed to a high-temperature atmosphere for a long time. Delayed tack type adhesive sheet, because the solid plasticizer is first dissolved by heating to develop adhesiveness, originally blocking should not occur at a temperature below the melting point of the solid plasticizer used, but actually The phenomenon in which the pressure-sensitive adhesive layer composition begins to dissolve at a temperature 20 to 30 ° C. lower than its melting point is observed from the measurement results of a differential calorimeter (DSC).

As a solid plasticizer used in a conventional delayed tack type pressure-sensitive adhesive sheet, phthalic acid diester and catechol diester have melting points of about 40 to 130.
Although various ester-based compounds in the range of ° C. are mentioned, taking as an example dicyclohexyl phthalate, which is most commonly used as a conventional solid plasticizer for a delayed tack-type pressure-sensitive adhesive sheet, the melting point is 64 ° C. ,
A phenomenon in which the delayed tack-type pressure-sensitive adhesive sheet produced using this solid plasticizer exhibits tackiness when stored in an atmosphere at about 45 ° C. is observed.

[0006] In either case of a roll or a state where it is cut into sheets and stacked, once blocking is induced, the pressure-sensitive adhesive-coated surface is bonded to the outer surface (the surface opposite to the pressure-sensitive adhesive-coated surface). However, this not only hinders paper feeding but also adversely affects printing on the outer surface.

As a means for preventing blocking, the incorporation of a slippery wax into the adhesive composition is disclosed in Japanese Patent Publication No. 21835/1987, but the effect of preventing blocking is insufficient. Not only that, on the contrary, the adhesiveness is reduced. In addition, although the blocking is improved by using a high melting point plasticizer, side effects such as a remarkable decrease in adhesive strength are caused, and the material is transported and stored under low temperature conditions where blocking does not actually occur. That is the current situation.

The second problem is that a difference occurs in the adhesive strength depending on the material of the adherend. That is, if the adherend is made of a material such as paper, glass, metal, etc., a stable adhesive force can be maintained for a long period of time, but it can be sufficiently adhered to a so-called polyolefin resin such as polypropylene or polyethylene even immediately after pasting. Not only is it not possible to obtain a force, but even if there is strong adhesiveness immediately after the application, the adhesive force decreases over time, which is a serious obstacle in practical use.
