Embodiment
Label adhesive sheet with excellent printing adaptability of the present invention, contain the base material that synthetic resin film forms, with the inking layer that on above-mentioned substrate surface, forms, form with the inside one side of above-mentioned base material, the binder layer that contains resin of binding property, with on above-mentioned binder layer, the peel ply of adhesive lamination strippingly, it is characterized in that above-mentioned base material synthetic resin film, be selected from not and stretch or by unidirectional tensile, has 150～1000MPa, the polymer resinous thin film that contains alkene of the tensile modulus of preferred 200～800MPa, and above-mentioned inking layer, the mixture that contains the component of polymer of the component of polymer of Ju You oxazolinyl and Mei You oxazolinyl is the principal constituent of resin.
As the resin that forms above-mentioned synthetic resin film, can use one or more optimization polypropylenes, new LDPE (film grade), medium-density polyethylene, high density polyethylene(HDPE), ethene-alpha-olefin copolymer, propylene-alpha-olefin copolymers, ethylene-ethyl acrylate copolymer, ethylene-vinyl acetate copolymer, the ethylene-methyl methacrylate methyl terpolymer, the positive butyl ester multipolymer of ethylene-acrylic acid etc. contains the fluoropolymer resin of alkene.
These contain the fluoropolymer resin of alkene, can use separately, also can use by making 2 kinds or the above mixture that is combined to form.In addition, these contain the fluoropolymer resin of alkene, as required, can contain photostabilizer, UV light absorber, antioxidant, a kind of weighting agent etc. or above additive.
The above-mentioned polymer resinous thin film that contains alkene is not stretch or by unidirectional tensile, as the method that forms this film, can use T mould extrusion molding, and is expansion-molded, any in the known film shaped method such as calendaring molding.
The synthetic resin film that uses as the adhesive sheet base material of the present invention, it can be the single layer structure body, it also can be film with multilayered structure, the preparation method of multilayered structure film without limits, can select by for example co-extrusion platen press, the extruded layer platen press, drying layer platen press, the preparation of currently known methodss such as lamination methods.
So-called above-mentioned multilayered structure film is meant the film that is made of 2 layers or above multilayer, by selecting to constitute the resin of each layer aptly, can be formed in flexibility according to purposes, in the tensile modulus etc., has the film of various physicalies.
For example, under the situation of the resin film of three-decker, as the middle layer, configuration ethylene-propylene copolymer resin, the ethylene-propylene-diene copolymer resin, propylene-hervene copolymer resin, elastomeric polypropylenes, Atactic Polypropelene, LLDPE, and/or flexible polyolefins based resin film such as new LDPE (film grade) are descended both sides thereon, the configuration homo-polypropylene, ethylene-propylene random copolymer, ethylene-propylene-butene-1 random copolymers, ethene-alpha-olefin copolymer, and vinylbenzene-alpha-olefin-resin films a kind of or that be combined to form more than a kind such as styrol copolymer, as the laminated film of surface hardness excellence, or the opposite configuration of the resin film by will forming above-mentioned middle layer and levels is carried out various combinations according to its purpose with the kind of the formation resin film of each layer as the laminated film of flexibility excellence etc., can obtain having the characteristic that requires, the performance multi-layer film.
Among the present invention, constituting the polymer resinous thin film that contains alkene of adhesive sheet surface substrate, use not stretch or unilateral stretching, is the film of 150～1000MPa as the tensile modulus of its performance.Its reason is in order to make label adhesive sheet of the present invention, to have the flexibility that is equal to the existing sealing tape that uses vinyl chloride resin film.By the way, when the tensile modulus of base material film surpassed 1000MPa, the flexibility of gained adhesive sheet was insufficient, and rigidity is strong excessively, the therefore too late flexibility of using the existing adhesive sheet of vinyl chloride film.On the other hand, during the tensile modulus of base material film deficiency 150MPa, because base material film is soft excessively, severing gained adhesive sheet becomes difficult shrilly.
And, constitute the polymer resinous thin film that contains alkene of the surface substrate among the present invention, its elongation at break is preferably 100～1000%, more preferably 200～700%, by the way, if the base material elongation at break less than 100% of film, the rigidity of film, therefore deformation resistance is strong, can not obtain having and contains the adhesive sheet of vinyl chloride resin film as the identical flexibility of existing adhesive sheet of base material.In addition, above-mentioned elongation at break surpasses 1000% film, because the easy tensile character of base material film, the fracture flexibility of operation of gained adhesive sheet becomes insufficient.
In addition, base material is used under the painted situation of synthetic resin film, can when the resin fusion, be added mixed colorant, form film from this pigmentary resin molten mass.As tinting material, can use organic system pigment, inorganic series pigments, dyestuff, carbon black etc.Painted tone is not particularly limited, and for example can be colored as white, nude, black, redness, blueness, yellow and green etc.When using the film of multilayered structure with film, can all add tinting material in the layer, also can only in part layer, add tinting material as base material.
Among the present invention, the thickness of the polymer resinous thin film of using in the base material that contains alkene is not particularly limited, and when using the replacement film of the existing adhesive sheet vinyl chloride resin film of conduct, its thickness is preferably 50～200 μ m.Its thickness is than under the thinner situation of 50 μ m, the adhesive sheet that use contains them is during as label, rigidity is crossed the low needs that can not satisfy in the practicality, in addition, when it surpasses 200 μ m, the flexibility of gained adhesive sheet becomes insufficient, is difficult to obtain having and the existing adhesive sheet that contains the identical flexibility of adhesive sheet of vinyl chloride resin film.
In the adhesive sheet of the present invention,, promptly do not form on the face of binder layer, form the inking layer of the resin of the resin contain Ju You oxazolinyl and Mei You oxazolinyl as principal constituent at least on the surface of base material film.Much less, also can form inking layer on the two sides of base material film.
In the adhesive sheet of the present invention, contain in the so-called inking layer, and the polymkeric substance of Ju You oxazolinyl, as long as any polymkeric substance of Cun Zai oxazolinyl can in the polymer molecule.For example have a polymkeric substance of You oxazolinyl, can be selected from the polymkeric substance that addition polymerization oxazoline compound monomer and at least a as required other monomer polymerization are obtained.As the above-mentioned monomer that contains addition polymerization oxazoline base, can enumerate 2-vinyl-2-oxazoline, 2-vinyl-4-methyl-2-oxazoline, 2-vinyl-5-methyl-2-oxazoline, 2-pseudoallyl-2-oxazoline, 2-pseudoallyl-4-methyl-2-oxazoline, 2-pseudoallyl-5-ethyl-2-oxazoline etc., 1 kind or 2 kinds or above mixture from them can obtain the polymkeric substance of Han You oxazolinyl.
As constituting other addition polymerization monomer that uses with the monomeric multipolymer of addition polymerization of above-mentioned Han You oxazolinyl, can enumerate for example (methyl) acrylic compound, unsaturated carboxylic acid compounds, unsaturated nitrile compound, unsaturated acyl amine compound, vinyl ether compound, the alpha-olefin compound, α, β-unsaturated aromatic monomer class etc. can be used a kind of or 2 kinds or above mixture in them.
