Description
Technical field
The present invention relates to the purposes (especially for the purposes of middle resin layer) that a kind of ultraviolet-curing resin composition, said composition be used for multiplayer optical disk, CD with cured layer of this resin combination; Be particularly related to the resin combination that is used for producing efficiently high density multilayered optical disk of future generation; It is high that this multiplayer optical disk is neutralized the fissility that mould (mould that CD is used) peels off from polycarbonate, and the warpage when solidifying, high temperature how the variation of the warpage under the wet condition is little.
Background technology
In recent years, the high capacity of CD progress is remarkable, and in order to increase memory capacity, the multi-layered type CD is popularized rapidly.Improve the technology of video disc recording capacity, can enumerate: high NA (opening number) change of the object lens of the short wavelengthization of recording/copying light beam, recording/copying light beam irradiates optical system, the multiple stratification of recording layer etc.Wherein,, compare with high NAization with the short wavelengthization based on the high capacity of the multiple stratification of recording layer, can be with the implemented with low cost high capacity.
For example, in having the DVD CD of two-layer recording layer, form two-layer recording layer and carry out range upon range of structure across transparent resin middle layer (below be also referred to as transparent middle resin layer).Particularly, be the structure of second transparent resin substrate of first transparent resin substrate that stacks gradually 0.6mm, first recording layer, the first semitransparent reflector rete, adhesive layer, transparent resin middle layer, second recording layer, second reflective coating, adhesive layer, 0.6mm.The formation method in the transparent resin middle layer of this moment; For example can enumerate: will be placed on the adhesive layer that forms on the first semitransparent reflector rete in order to the ultraviolet-curing resin composition that forms the transparent resin middle layer; The guiding that will have a recording/copying light beam is carried side placed on it with the transparent resin pressing mold of relief patterns such as guide channel; Be rotated coating, formed ultraviolet-curing resin composition layer is solidified after, pressing mold is peeled off; With the concavo-convex surface that is transferred to ultraviolet-curing resin composition, and the method in formation transparent resin middle layer; Perhaps; After being formed at the solidfied material layer of said resin combination on the pressing mold; To carry with the pressing mold of this solidfied material layer and be placed at the adhesive layer placed on the first semitransparent reflector rete and form with on the resin, form adhesive layer through rotary coating after, this adhesive layer is solidified; Then this pressing mold is peeled off from the solidfied material layer of said resin combination, and the method (transfer printing) in formation transparent resin middle layer.
In the Blu-ray Disc; Read-only optical disc is the recording figure forming of transfer printing pit shape on as the single face of the polycarbonate substrate of the for example diameter 120mm of substrate, thickness 1.1mm; Surface at this substrate forms first reflective coating as first recording layer, for example silver alloy reflective layer.In addition, on first reflective coating, form the transparent resin middle layer that transfer printing has the recording figure forming of pit shape, go up second reflective coating that forms as second recording layer, for example silver alloy reflective layer in this transparent resin middle layer (intermediate coat) across adhesive layer.Be formed on the formation of this reflective coating laminated transparent resin layer then.In addition, the silver alloy reflective layer carries out film forming in a vacuum through for example sputtering method method is proposed.
Recording type optical disc for example is formed on surperficial laminated first reflective coating, first dielectric layer, first recording layer, second dielectric layer of substrate that transfer printing on the single face of polycarbonate substrate of diameter 120mm, thickness 1.1mm has the recording figure forming of pit shape, and then on second dielectric layer, stacks gradually the structure of transparent resin middle layer, second reflective coating, the 3rd dielectric layer, second recording layer, the 4th dielectric layer and transparent resin layer across adhesive layer.
At this moment; The ultraviolet-curing resin composition that will be used to form the transparent resin middle layer across adhesive layer is coated on reflective coating or the dielectric layer; And by being pressed on the transparent resin pressing mold of guiding with recording/copying light beam with relief patterns such as guide channels; After ultraviolet-curing resin composition is solidified, pressing mold is peeled off, be transferred to the surface of ultraviolet-curing resin composition and form recording type optical disc (transfer printing) concavo-convex.
At this, in read-only optical disc, the transparent resin middle layer forms second reflective coating usually on its male and fomale(M&F), and opposing face is then gluing across the adhesive layer and first reflective coating.In addition, in recording type optical disc, this transparent resin middle layer forms second reflective coating usually on its male and fomale(M&F), and opposing face is then gluing across the adhesive layer and second dielectric layer.
Generally speaking, this transfer printing is called 2P (Photo Polymerization; Photopolymerization) method, employed ultraviolet-curing resin composition is called the 2P agent.
The transparent resin that the transparent resin pressing mold is used can be enumerated: acrylic resin, methacrylic resin, polycarbonate resin, polyolefin resin (particularly noncrystalline polyolefin), polyester resin, polystyrene resin, epoxy resin etc.Wherein, viewpoints such as the fissility after the 2P agent is solidified, agent of low hygroscopicity, shape stability consider that preferred noncrystalline polyolefin is considered from the viewpoint of material cost, the optimization polycarbonate resin.Therefore; For cutting down cost; The method of the optical recording media (multi-layered optical recording medium) that a kind of manufacturing has several record layers is proposed; Even this manufacturing approach uses cheap polycarbonate to neutralize mould, its fissility might as well and make yield rate improve, and has also developed the resin (patent documentation 1) that is suitable for this manufacturing approach.
At present, the main flow of the ultraviolet-curing resin composition during as use 2P method for example can be enumerated: the composition that (a) contains prepolymer, monomer and the Photoepolymerizationinitiater initiater that can carry out the optical free radical polymerization; (b) contain the composition of prepolymer, monomer and the Photoepolymerizationinitiater initiater that can carry out the light cationic polymerization; (c) be mixed with the composition etc. of optical free radical polymerism and cationically polymerizable composition.
Prepolymer can be enumerated: various epoxy radicals (methyl) acrylic ester ((methyl) acryloyl group of addition in the epoxy skeleton and obtain material) is ((methyl) acryloyl group of addition in the carbamate skeleton and obtain material) etc. or/and carbamate (methyl) acrylic ester.These compositions, appreciable impact is from the such mouldability of the release property of the pressing mold demoulding respectively; And to the desired characteristic of the such CD of tackiness, moisture-proof, the flexibility of reflective coating or dielectric layer.
The general use of monomer has the monomer of (methyl) acryloyl group as functional group.In addition, also can use monomer with vinyl.Generally speaking, the viscosity of prepolymer is high, is difficult to separately use as the 2P agent, therefore uses monomer as reactive diluent.For example, through using the above monomer of 3 officials ability, the cross-linking density of solidfied material is increased, and improve hardness, Young modulus, humidity resistance.
When making multiplayer optical disk, during from fissility difference that the transparent resin pressing mold is peeled off, can produce the part in transparent resin middle layer and the defective that the transparent resin pressing mold is together peeled off.During transfer printing property difference, can produce mistake during recording/copying.When warpage is big after the ultraviolet curing, can't recording layer or reflective coating be formed uniformly on formed relief pattern, when perhaps being DVD, second substrate of can't fitting when perhaps being Blu-ray Disc, can't be formed uniformly the light-transmitting layer of 0.1mm.In addition, when relief pattern produced distortion under high temperature wets condition more, the recording characteristic of first and second recording layer (for example jittering characteristic) can't reach equal.
The 2P agent that patent documentation 2 to 5 is put down in writing uses metal pressing mold on the layer that is formed on the glass substrate, to form relief pattern.In addition, various 2P agent have also been put down in writing in the patent documentation 6 to 10.
