Abstract

PURPOSE: To obtain a base material having excellent tacky property and capable of reducing coating amount of a tacky agent without lowering laminate processability by using a composition comprising an olefinic resin and a tackiness-imparting resin as a laminating material on the coating face side of the tacky agent. CONSTITUTION: (A) One face or both faces of a porous base material (e.g. paper, cloth or nonwoven cloth) is laminated with (B) a composition containing a tackiness-imparting resin mainly containing an olefinic resin (preferably a low- density polyethylene or an ethylene-vinyl acetate copolymer, etc., having 1-30g/10min melt flow rate) and a tackiness-imparting resin having <=15 acid value (e.g. a petroleum-based resin or a rosin-base resin) to obtain the objective base material. A laminate-treating face of the base material is coated with a tacky agent to obtain a tacky tape. The containing ratios of the tackiness- imparting resins in the tackiness-imparting resin-containing composition are preferably <=30wt.%, more preferably 5-20wt.%.

However, these thermoplastic elastomers are expensive. Therefore, in order to reduce the cost, it is desired to reduce the content of the thermoplastic elastomer in the pressure-sensitive adhesive. However, when the content of the elastomer in the pressure-sensitive adhesive is reduced, it is natural that the adhesive and adhesive properties of the pressure-sensitive adhesive tape are reduced. However, there is a problem that it becomes difficult to maintain good. Furthermore, some adhesive thickness is required to maintain good tack and adhesive properties. However, when applying an adhesive to a porous substrate having a large unevenness such as cloth and having a high adhesive penetration, the thickness of the adhesive must be increased unless the coating amount of the adhesive is increased. I can't keep up. In any case, the pressure-sensitive adhesive tape using the pressure-sensitive adhesive made of a thermoplastic elastomer such as SIS or SBS has a problem of high cost.

In order to reduce the cost, it is necessary to reduce the penetration of the adhesive into the porous base material. This is because the surface of the porous base material to which the adhesive is applied is reduced. It can be solved by laminating. However, in this case, since the olefin-based resin conventionally used for the laminate resin generally has poor adhesiveness with the pressure-sensitive adhesive, it is peeled off after sticking the pressure-sensitive adhesive tape, and then, between the laminate layer and the pressure-sensitive adhesive layer. Peeling occurs and the adhesive remains on the adherend side, so-called a phenomenon of anchor anchorage failure of the adhesive is likely to occur. SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems, to reduce the amount of adhesive applied, and to provide an adhesive tape having excellent adhesion and adhesive properties.

I tried extrusion lamination with a die, but a large number of holes were generated in the extruded film, a uniform film could not be obtained,
It could not be laminated.

03) was laminated so that the amount of lamination was 70 g / m 2 , and treated with a release agent in the same manner as in Example 1 to prepare a base material for an adhesive tape. Then, the pressure-sensitive adhesive used in Example 1 was applied to the surface not laminated to give a total thickness of 30.
Hot-melt coating was applied so that the thickness became 0 μm to obtain an adhesive tape. Table 1 shows the test results.

EFFECTS OF THE INVENTION The pressure-sensitive adhesive tapes obtained in Examples 1 to 3 of the present invention have the same pressure-sensitive adhesive as the conventional cloth pressure-sensitive adhesive tape, even though the amount of pressure-sensitive adhesive applied is 70 g / m 2 less. The thickness can be maintained, the adhesive strength is the same, and there is no problem with the anchoring property of the adhesive. In Comparative Example 1, the tackifying resin was not added to the laminate resin, but the anchoring property of the pressure sensitive adhesive was insufficient. In Comparative Example 2, the tackifying resin had a large acid value and could not be laminated. In Comparative Example 3, the cloth adhesive tape is produced by the conventional method, but the amount of the adhesive applied must be large and the cost is high. Further, Comparative Example 4 has the same adhesive coating amount as that required in Example 1 on the substrate prepared by the conventional method,
This is a prepared adhesive tape, and its adhesive properties are extremely inferior.
