DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an adhesive composition suitable for manufacturing adhesive tapes and sheets. The object of the present invention is to provide an adhesive composition that can pressure-sensitively adhere to the surface of an adherend and can be peeled off after use.

Since this method uses a large-scale solvent, it has problems such as flammability and durability, so in recent years 1. Emulsion type adhesives and hot melt type adhesives have been developed and put into practical use instead of solvent type adhesives. However, emulsion-type adhesives require a long drying time and high energy consumption because the water contained in them is heated and dried, and the use of emulsifiers during synthesis results in poor water resistance. It has drawbacks such as being difficult to apply to plastic films because of its poor adhesion to films. In addition, hot melt adhesives are attracting particular attention due to their advantages such as non-pollution and high speed.
Currently, compositions with synthetic rubber thread elastomer as the main polymer are mainstream, but due to their tendency to flow when heated, they have limited heat resistance, and because they contain tackifiers, plasticizers, etc., deterioration over time is unavoidable. Furthermore, since the main polymer contains a conjugated double bond, it is susceptible to deterioration by light and has poor weather resistance.

Hot-melt adhesives, especially acrylic-based hot-melt adhesives, have been attracting attention in recent years due to their excellent weather resistance, but they must have enough fluidity to be able to be used as wall coverings at high temperatures. For this reason, it is not possible to use polymers having a high molecular weight and it is difficult to carry out effective crosslinking, so that a material with excellent both adhesiveness and cohesive strength has not yet been obtained.

In order to be easily pasted, the adhesive strength according to the test method specified in JI8ZO237K must be at least 5o2/251m.
It requires a width of medium or larger, preferably 100F/25m or more. If the adhesive strength is less than 50 S'/2510+width, some parts may not be pasted, or even if it is pasted, it will easily peel off during handling and processing, causing problems in use. On the other hand, from the viewpoint of peeling workability, it is preferable that the adhesive force is low, and if it exceeds 300 g/25m, it is not preferable because it will actually lower the peeling workability. The present invention has been made in consideration of the drawbacks and preferable adhesive strength of these conventional masking tapes and sheets, and by having the structure described in the claims (main), the conventional acrylic thread foam, We have created an adhesive composition that has low viscosity, excellent applicability, can be applied at high speed, is non-polluting, exhibits adhesive strength without any problems in use, and can be peeled off after use without impairing the properties of a melt-type adhesive. This is what I was able to successfully obtain.

First, as a homopolymer of acrylic acid ester monomers represented by the general formula CH,: CHCOORI (where Bt is an alkyl group having 2 to 14 carbon atoms) or a copolymer of the acrylic esters having different R1, acrylic acid- It is a homopolymer of acrylic esters such as 2-ethylhexyl, butyl acrylate, and ethyl acrylate, or a copolymer of these acrylic esters. Since the acrylic acid ester monomer represented by the above general formula is non-polar, the adhesive strength of the homopolymer or copolymer is weaker and the removability is better than when using a polar monomer. The homopolymer and copolymer have a molecular weight of 000 to 300,000.
Those within the range of are used. The above acrylic acid esters are used because they are widely used in conventional acrylic adhesives and have excellent adhesive properties.The molecular weight is defined as 5,000 to 300,000 because the molecular weight is , ooo or less, coating suitability is excellent, but cohesive force cannot be obtained after electron beam curing, and a o a

This is because although the cohesive force is excellent in the above, the viscosity becomes too high when used as an adhesive, and the suitability for coaching is poor. In addition, in the present invention, any of the above-mentioned homopolymers or copolymers can be used, but three of 2-ethylhexyl acrylate, ethyl acrylate and butyl acrylate

Add 5 to 40 parts by weight to water. In the above, the reason why the amount is 5 parts by weight or more is that the addition amount of 5 parts by weight is insufficient for diluting the homopolymer and reducing the viscosity of the homopolymer copolymer and reducing the viscosity.

This is because if the amount exceeds 40 parts by weight, the viscosity decreases, but the cohesive force after curing by irradiation with ionizing radiation decreases, resulting in insufficient tackiness.

The pressure-sensitive adhesive composition of the present invention is described by Mrad $ et al. 5 Q M
Using a rad radiation dose may provide a more sufficient cure, but adjusting the radiation dose may provide varying degrees of adhesion and other properties within a given range. In addition, since the adhesive composition of the present invention contains the homopolymer or copolymer of the acrylic ester, it can exhibit the weather resistance of the acrylic ester and has excellent adhesive properties, and can be diluted with the acrylic ester monomer. The acrylic acid ester monomer itself polymerizes when irradiated with ionizing radiation, so the coating and drying process is fast and pollution-free, making it a solvent-diluted adhesive. Compared to the composition, it cures approximately 100 degrees even at the same viscosity and the same coating position (coating dark standard), so it is easy to increase the amount of coating. Historically, when irradiated with ionizing radiation, in addition to the polymerization of the acrylic ester, the polyfunctional acrylic ester participates and cross-links three-dimensionally, resulting in a large cohesive force and no cohesive failure during re-peeling. It has the advantage of being able to be peeled off without leaving traces of the adhesive composition.
