HD-DVD

The HD-DVD optical media formats is proposed and exploitation by Toshiba and NEC, and as described in DVDForum, during current DVD made, HD-DVD was made up of two kinds of matrix that are bonded together.At least a coded message that is loaded with in two kinds of matrix.At least a in two kinds of matrix is optically transparent to reading laser.The similar part of HD-DVD form and existing DVD-9 design is, described as DVD Forum (www.dvdforum.com) and ECMA standard (http://www.ecma-internationa1.org/publications/standards/Ecma-2 67.htm), two-layer at the most by read laser from the dish one side read.The two-layer data Layer and the DVD-9 structure of HD-DVD dish are similar, but track pitch is narrower, and the concave point structure is littler.The optical maser wavelength of reading that HD-DVD reads equipment is approximately 405nm.

The invention discloses the reactant that many kinds can be used for HD-DVD dish alone or in combination, make that at least a portion coded message on the HD-DVD dish irreversibly becomes and can't read by reading laser after at the fixed time.The desired reactant of the present invention can be positioned at HD-DVD dish interior surface and/or on and/or read within the light path of laser and/or outside the light path.Fig. 1 example be the limited broadcast embodiment 5 of HD-DVD according to the invention.Fig. 1 has shown two matrix 10 and 15, and its mesostroma 10 is commonly referred to as the L0 face, and as mentioned, light beam passes this face and reads coded message.Matrix 15 is commonly referred to as the L1 face.Reflection horizon 20 and 25 quilts one deck intervening layer 30 at least separate.In the embodiment illustrated, read inhibiting is arranged in 30, and wherein can be masking compound such as for example chemically-reactive dyes and/or disrupting agent for example corrode one of reflexive material in one deck reflection horizon at least to read inhibiting.Coded message can be read by light beam (a branch of or multi beam) 40.

The HD-DVD form uses with standard DVD and similarly coils structure.Therefore it and existing manufacture method are highly compatibles.Manufacturing begins with the injection moulding of two thick disk base materials of 0.6mm.Data may be molded in one or two matrix, and this depends on that what making is individual layer or dual layer discs.The matrix that will have data Layer then is bonded together two matrix then with half reflection and/or reflectance coating metallization.In double-layer product, binder resin is within the laser light path.For single-layer products, binder resin is not usually within light path.As U.S. Patent application 10/163,473,10/163,855,10/163,472,10/837,826,10/163,821,10/651,627 and United States Patent (USP) 6,756,103 is described, and by reference that it is all incorporated in full at this, single data layer can be overturn physically and be moved to L1 matrix, produce the mobile data layer thus and make laser must pass the single-layered disk structure of binder resin, thereby for individual layer HD-DVD, bonding coat is placed within the light path.On this meaning, HD-DVD product and U.S. Patent application 10/163,473,10/163,855,10/163,472,10/837,826,10/163,821,10/651,627 and United States Patent (USP) 6,756,103 (it is all incorporated by reference) at this in disclosed DVD form and DVD-9 product similar.Difference is to read the Wavelength of Laser difference, and is as indicated above.Make like this and can pass through tightr, the big or small littler higher packing density that obtains of concave point of track pitch, storage capacity is brought up to the 15G byte of individual layer HD-DVD from the attainable 4.7G byte of standard DVD-5.

Blu-ray

Propose and exploitation and comprise single-matrix by a number of companies by the Blu-ray format optical that Sony advocates.It is optically transparent that the matrix of Blu-ray dish does not need reading laser, because data read by the thick overlayer of about 0.1mm.This overlayer perhaps is adhered on the matrix within the light path of laser reading, and/or is spin-coated on the matrix one or more layers.Desired reactant of the present invention and/or read inhibiting and/or read to limit agent and can be used for Blu-ray dish alone or in combination make that at least a portion coded message on the Blu-ray dish irreversibly becomes and can not read by reading laser after at the fixed time.The desired reactant of the present invention can be positioned at the Blu-ray panel surface inside and/or on and/or read within the light path of laser and/or outside the light path.

In an embodiment according to the invention, chemically-reactive dyes is incorporated in any overlayer that forms Blu-ray dish light path, and after chemically-reactive dyes is exposed to stimulation, stops that reading laser reads coded message.What Fig. 2 showed is limited broadcast Blu-ray embodiment 105 according to the invention.Fig. 2 has shown that support has the matrix 130 of the coded message 140 of reflection horizon 120 and bonding coat 125, and it has overlayer 115 and hard conating 110.Read inhibiting can be arranged in one deck at least of bonding coat 125, overlayer 115 and hard conating 110.Coded message 140 can be read by light beam 135.In the embodiment illustrated, read inhibiting can be that masking compound for example corrodes one of reflexive material at least one reflection horizon such as for example chemically-reactive dyes and/or disrupting agent.

What Fig. 3 showed is limited broadcast Blu-ray embodiment 105 according to the invention, that do not have hard conating 110.One of in the embodiment illustrated, read inhibiting can be a masking compound, such as for example chemically-reactive dyes, and/or disrupting agent, for example corrode the reflectivity at least one reflection horizon and be arranged in bonding coat 125 and the material of one of overlayer 115.

The Blu-ray dish uses the manufacture method that is different from standard DVD and HD-DVD.In the Blu-ray dish, disk base material is removed from light path, and this has eliminated the problem relevant with the stress induced birefringence of molded matrix.Second reason that disk base material is removed from the light path of reading laser is that this has reduced the dish inclination (disc tilt) of reading the surface.When the surface of dish can tilt by the generation dish when reading the laser out of plumb.System with high numerical aperture (NA) lens tilts more responsive to dish.In Blu-ray, numerical aperture increases to 0.85mm from the 0.6mm of standard DVD NA.The recording layer and/or the data storage of Blu-ray dish are placed on the surface of 1.1mm matrix, are protected by the 0.1mm overlayer.Overlayer is within light path, and is much thinner than standard DVD L0 layer and HD-DVD 0.6mm matrix.Because reading optical element can be more approaching with data Layer, so 0.85 NA makes high numerical aperture lens to use at 405nm wavelength place.The matrix birefringence is eliminated, and the surface tilt problem reduces.But, introduced new problem, promptly need to make overlayer, and with respect to standard DVD and HD-DVD form according to very strict specification, surface imperfection such as cut or fingerprint are much serious problems.The Blu-ray group that Sony leads developing can be under situation about not scratching the hard conating of wiping or cleaning.These hard conatings also within light path, are spin-coated on the tectal surface usually.

According to an embodiment according to the invention, limited broadcast Blu-ray dish is disclosed.Limited broadcast Blu-ray dish combines the dyestuff absorption techniques in light path, i.e. reactive explosive and/or read inhibiting and/or read to limit agent.Reactive explosive is made response to stimulation, thereby becomes inhibition at least a portion data Layer to be read the opaque substantially state that laser reads from the state-transition of substantially transparent under the 405nm wavelength.Be selected within the 0.1mm overlayer and/or surface coating that those dyestuff disclosed herein can be incorporated into the Blu-ray dish.This is positioned at reactive explosive and reads among the light path of laser.This technology is applied to individual layer and double-deck Blu-ray dish.

Chemically-reactive dyes can be incorporated among the light path random layer or all within the layer, comprise bonding coat, 100 microns cladding materials and/or hard conating.Mordant can be adjacent to the reflection horizon, can be in conjunction with bonding and overlayer, and the latter also can be used as hard surface coatings.

What Figure 16 illustrated is embodiment according to the invention.L1 matrix 1405 comprises the Blu-ray data layout.L1 matrix 1405 is bonding with L0 matrix 1410 via bonding coat and/or adhesion layer 1440.L0 matrix 1410 comprises the HD-DVD data layout.The top of L1 matrix 1405 comprises the two- layer reflection horizon 1415 and 1420 that is separated by intervening layer 1445.L1 matrix 1405 further comprises bonding coat 1412 and overlayer 1414.The top of L0 matrix 1410 comprises the two- layer reflection horizon 1425 and 1430 that is separated by intervening layer 1435.Blu-ray and HD-DVD form read via the matrix face that light beam 1450 and 1455 passes himself respectively.Read inhibiting has limited Blu-ray and HD-DVD form and/or its a part of life-span at least.Read inhibiting is arranged in one deck at least of intervening layer 1445, binder couse 1440, intervening layer 1435, bonding coat 1412 and overlayer 1414.

What above Figure 16 illustrated is the mixture structure that is combined with the Blu-ray dish of HD-DVD CD.This is unique, novel structure, and it is combined with in individual CD and satisfies two kinds of different-format specification data layers that proposed.By every kind of form being used conventional combination and spin coating resin and/or other overlayer structure, two kinds of data Layers all can be permanent played data layers.In bonding coat and/or overlayer and/or disk base material and/or reflection horizon, introduce reactive explosive and/or limited broadcast mechanism, for part or whole data Layer add limited ability to play.In addition, but the present invention also estimate to contain within the dish structure of Blu-ray and HD-DVD data Layer in conjunction with limited playback features, permanent playback features and/or recording layer at individual.

The optical medium recordable, that the life-span is limited

In the application of writing down numerical data (it includes but not limited to audio or video, as music or film) as required, it may be suitable can recording the information in to all or part institute recorded information provides on the CD of limited ability to play.This can also combine with prerecorded area or the data Layer in the dish structure.

In another embodiment according to the invention, disclose and to be used for (comprising at issuing point selectivity record data, for example, but be not limited to the consumer and wish software, song, special edition, music video, positive or the video clips bought) optical medium.The method of distribution and record can be in the consumer service station of the retail location with relative recording equipment and suitable package system, or is directly used in the fully integrated retail kiosk of automation mechanized operation process and transaction by the consumer.

With recordable data layer and the combination of finite lifetime mechanism, designed the optical disc product that satisfies these user demands.This essential structure can combine with any previous embodiments, comprises the prerecorded second layer in limited DVD playing back-9 form.But also can use second recording layer.

In an embodiment according to the invention, dish structure is followed standard DVD-9 structure, and promptly bottom L0 coils that half sheet and/or matrix and top L1 coil half sheet and/or matrix phase is bonding.But then this there is groove matrix to apply, and uses the half reflection film metallization, can write down the L0 data Layer in DVD-dual layer-9 structure, to produce with the DVD recording dye.Read to limit dyestuff and be integrated into the adhesive that is used for bonding L0 and L1 matrix.L1 matrix is molded as prerecorded data Layer, and this is very typical in DVD-9 L1 data Layer, and metallizes with total reflection layer.Randomly, but in dual-layer recordable structure, can use second recording layer.In arbitrary product configurations, reading in the bonding coat limited dyestuff and limited after preset time visit whole on second data Layer or institute's favored area, limits the visit to all or part of data of being stored on the CD.Interaction between reflection horizon and the reactive bonding layer can prevent with the cushion that puts on the reflection horizon before bonding.

Dish is through writing with in inserting player the time, and L1 will be identified as and be recorded, and L0 can supply record.Prerecorded L data Layer provides data as for the ability on the L1, and it can be used as verification (check) zone or is provided for the software that player, retail kiosk or register are used.In the dish data structure, use the verification zone can be used to improve the capacity that can write down limited broadcast product, limit limited play area and provide that write down and visit prerecorded information selected portion.The L0 layer can also have prerecorded data in the recorded data zone, it contains the information that is useful on player, record driving or retail kiosk, to be used as check disk zone, application message or product configurations information.

The reactive adhesive that uses part to distribute in bonding coat can be used to also stop that reading laser reads and can write down and/or the ability of the restricted area of pre-recorded data layer.In this way, medium can be configured to optionally to make that the whole of record in the dish and/or prerecorded data or its are a part of has a limited playback features.

Although illustrate and described a plurality of embodiment of the present invention (comprising preferred embodiment), will be appreciated that and under the prerequisite that does not depart from spirit and scope of the invention, to carry out multiple variation and/or combination.

The controlled application of read inhibiting

These embodiments provide the optical medium that contains the coded message with two kinds of independent life-spans (finite lifetime and infinite life).Produced the DVD-9 that only on the part of dish, has read inhibiting.Although this realizes that on the DVD-9 form this technology can be applicable to all forms and structure.Realized writing, thereby or restriction to the visit of the data that are not subjected to physical barriers, perhaps can visit these data.These technology of writing are U.S. Patent applications 10/163,473,10/163,855,10/163,472,10/837,826,10/163,821,10/651,627 and United States Patent (USP) 6, disclosed person's expansion in 756,103 is incorporated herein by reference whole these full patent texts at this.Use a part not have read inhibiting to stop laser and the optical medium of writing, if so that can visit a part that allows the layer that will forever play, simultaneously other data at least its major part physics that on all players, becomes not can read.

Make the dish that the chemically-reactive dyes jointing material is located at internal diameter (ID), middle footpath and the external diameter (OD) of dish with the double allocation system assignment.What Figure 17-20 illustrated is the distribution of read inhibiting according to the invention (one or more).Figure 17 has illustrated the read inhibiting that is confined to external diameter wedge-like portion 1510.Remaining area 1505 can be bonding agent and/or second reading inhibitor.Figure 18 has illustrated the read inhibiting of the big wedge-like portion 1610 that is confined to external diameter.Remaining area 1605 can be bonding agent and/or second reading inhibitor.Figure 19 has illustrated the read inhibiting that is confined to around the zone of internal diameter 1710.Remaining area 1705 can be bonding agent and/or second reading inhibitor.Figure 20 has illustrated the read inhibiting that is confined to around the zone of internal diameter 1810.Remaining area 1805 can be bonding agent and/or second reading inhibitor.

Be distributed with two kinds of binder resins if standard is distributed in the circulation, then can realize than the great minimizing on expensive chemically-reactive dyes binder resin or the corrosion chemicals binder resin consumption by very little device and/or process reform.

The benefit of two distribution technologies comprises: active adhesive consumption reduces (expense reduction thereupon); Consumption reduces makes dye strength increase (chemical stability raising); With separating of activity/inertia adhesive: this can make within inertia adhesive chemicals realizes the second chemical disabling mechanism, for example on the different piece of CD with the chemically-reactive dyes chemicals with corrode chemicals and combine.Disclose second disabling mechanism in U.S. Patent application 10/163,473,10/163,855,10/163,472,10/837,826,10/163,821,10/651,627 and the United States Patent (USP) 6,756,103, it all has been incorporated herein by reference in full at this.

Preparation two only has the DVD-9 of reactive reagent and/or material (for example chemically-reactive dyes) on the part of dish.Do not have reactive reagent on this part that causes coiling, thereby will can not stop laser to read coded message in this zone.A part (this part does not have reactive explosive) that makes it possible to visit the L1 layer is write in use, and it will be permanent the broadcast, and the data on whole simultaneously will have at least most of becoming and not can read on all players.

Two distribution systems can also be used to reducing the expense of chemically-reactive dyes referred to above or corrosion material.In order to obtain the performance that is equivalent to Flexplay DVD-5 or Flexplay DVD-9, the reactive bonding resin can put on the ID place of dish, but not the reactive bonding resin puts on outside this radius.Then two kinds of materials are rotated together, make reactive explosive only stay the interior section place of dish, this will still cause the boot section to be lost efficacy, and cut off the visit to dish navigation menu structure.After predetermined stimulation activated inner chemically-reactive dyes or reactive etching material area, dish will no longer can be brought into play function.

The optical deterioration of limited broadcast optical medium is exposed to the stimulation of oxygen for example via chemically-reactive dyes or reactive etching agent and takes place.For example, oxygen is subjected to getting involved the restriction of the normal incidence body diffusion of material layer by polycarbonate " mute (dummy) " matrix and any other to the transmission of responding layer.Oxygen transmits and can also take place spreading by dish-edge at the interface between the DVD-5 matrix of reverse making (reverse-mastered) and the mute matrix or between the L0 of DVD-9 and the L1 substrate edge.Diffusion major limitation in dish-edge is at internal diameter and the external diameter of DVD.The oxygen rate of diffusion that changes any intervening layer between external environment condition and the oxygen activity layer will significantly impact the optical deterioration speed of limited broadcast medium, thereby the mechanism of control product probable life is provided.

Dish-edge diffusion control

Dish-edge rate of diffusion will be different from the diffusion of normal incidence body; because responding layer or expose at this narrow zone; perhaps stopped (for example acrylate protective finish) protection by second, its composition is different with the composition of other parts of typical limited broadcast optical media systems usually.If the body rate of diffusion is enough low, then the diffusion of dish-edge will be preponderated, and makes it possible to come by the preferential optical deterioration of limited broadcast optical medium internal diameter or outer radius the probable life of console panel.The diffusion of dish-edge can be controlled by composition and thickness that dish-edge stops.By carry out required playability checking at predetermined point place, realize losing efficacy then by the preferential dish of dish-edge diffusion near limited broadcast optical medium internal diameter or external diameter.By on mute matrix, using film diffusion to stop; oxygen rate of diffusion by mute matrix (for example PMMA matrix) descends; or stop (for example protection stops or the semipermeability coating) by the local diffusion on the mute stromal surface, can realize accounting for overriding dish-edge rate of diffusion.

For from removing, developed following adhering technique: make chemically-reactive dyes or corrosion chemicals outward flange, and still realize suitable bond property and spacer thickness away from dish for the edge diffusion of dish inefficacy principal element.This embodiment be included in the adhesion process with two kinds independently material distribution to dish.Realize two distribution system concurrent workings, to reduce cycling time.The reactive bonding resin is applied to PanIDChu, permits the binder resin of non-reacted or second disabling mechanism then to be applied to outside this radius.Then two kinds of materials are rotated together, make reactive explosive only stay the interior section place of dish, this will still cause the boot section to be lost efficacy, and cut off the visit to dish navigation menu structure.After predetermined stimulation activated inner chemically-reactive dyes or reactive etching material area, dish will no longer can be brought into play function.The life-span of institute's memory encoding information or view window (viewing window) are by the key reaction reagent decision of disk center on the dish.Adopting U.S. Patent application 10/163,473,10/163,855,10/163,472,10/837,826,10/163,821,0/651,627 and United States Patent (USP) 6,756, (it all is incorporated herein by reference in full) under the situation of second disabling mechanism described in 103 at this, second material that is coated on outside the ID can contain the reactive etching chemicals, and it will make dish corrode the reflection horizon after not can read at chemically-reactive dyes.By reducing the volume of every dish material therefor, can also use two distribution systems to reduce the cost of chemically-reactive dyes or corrosion material.

The body diffusion control

If do not preponderate in limited DVD playing back system mid-game-edge diffusion, then the pre-determined stimulus rate of diffusion of the passing assembly normal incidence body rate of diffusion that will mainly be coiled parts in the assembly limits.Because the rate of diffusion of passing total reflection layer (for example 60nm aluminium) can be ignored, the body diffusion of passing the bottom substrates that scribbles semi-reflective layer and any diffusion barrier that puts on matrix or L0 matrix will determine the overall rate of diffusion of responding layer.Possible body diffusion control mechanism has been described in the following advantageous applications:

1) diffusion limited base composition

2) thin stopping or semi-permeable coating diffusion barrier

3) film diffusion stops

4) in matrix, reflection or bonding coat, comprise antioxidant

5) in chemically-reactive dyes layer or reactive etching layer, comprise reductive agent

L0 of oxygen diffusion limited (DVD-9) or bottom mute (oppositely DVD-5) base composition

Polycarbonate pc (PC) is adopted in current CD manufacturing.The oxygen permeability of polycarbonate is approximately 100 ^Cc-mm/ _m2 _-dReduce the oxygen permeability of L0 or mute matrix, and the rapid kinetics of conglutination reaction dyestuff binder resin, make product decay dynamics be subjected to the restriction of mute matrix oxygen infiltration rate single-mindedly.For example, the dish of being made by polymethylmethacrylate (PMMA) has significantly increased reproduction time, because compare with conventional polycarbonate pc, the oxygen permeability of material is much lower.The material character of perviousness aspect is also highly stable, makes that product stability regularly is very excellent and can repeat.Following figure has illustrated the reproduction time of attainable prolongation when the body rate of diffusion of oxygen changes at an easy rate, and it is used to have the oxygen reactive system of Flexplay chemically-reactive dyes chemicals:

Figure 21 has illustrated the reproduction time that uses the prolongation of standard P MMA, PC and aluminium barrier film.

Figure 22 has illustrated the decay rate of the sample of being made by PMMA matrix, and it has two kinds of different oxygen infiltration rates, demonstrates the ability that reproduction time is adjusted.

Thin coating diffusion barrier

By shallow layer being applied to the inside surface or the outside surface of L0 or mute matrix, can realize product dynamic (dynamical) control that decays.The refractive index of coating is approximately 1.55, and is very low in the optical absorption at 650nm place.Coating spreads by spin-coating method, and variation in thickness is no more than 10% (absolute value).The thickness of coating and perviousness will determine the decay of product.The normal direction coating thickness of 10 m should be commercially available optical hard coating suitable product decay dynamics is provided.Can also add antioxidant and/or reductive agent in these coatings.Figure 23 has illustrated coating according to the invention.

Film diffusion stops

Oxygen or other pre-determined stimulus can reduce by the applied film diffusion barrier to the body rate of diffusion of responding layer.Film diffusion stops the inside surface or the outside surface that can be applied to mute matrix or L0 matrix.In fact, film can be applied to the arbitrary surfaces between environment and the responding layer.By film composition, thickness and appearance structure, can control the rate of diffusion that stops by film diffusion.Many kinds of materials (metal, metal oxide etc.) all can be used to produce film diffusion and stop, as long as can use accurate deposition technique such as sputter or physical vapour deposition (PVD) to generate corresponding barrier film in the CD manufacturing environment.

Film diffusion stops for being used to read wavelength table recorded in the optical medium reveals minimum optical reflection and absorption.If be applied to the outside surface of matrix, it also should show the favorable mechanical wearing and tearing and the performance of breaking.

The aluminum oxide film that sputter applies stops for the oxygen diffusion provides significantly.Oxygen is passed the restriction of crystal grain-border (grain-boundary) diffusion of sputter coating alumina film to the infiltration rate of oxygen activity adhesive.For the room temperature diffusion process, the grain boundary rate of diffusion is than the fast several magnitude of body rate of diffusion.It is minimum to adopt ultra-thin metal oxide film to make undesirable mute matrix reflection and metal film optical absorption reduce on specular surface, and the intensity from the data-signal of reverse making matrix is remained within the acceptable working level.

Preferential optical deterioration

The limited DVD playing back that adopts above-mentioned film diffusion to stop can further customize, and makes the rapid variation of aluminium oxide sputtered film thickness can cause occurring preferentially losing efficacy in DVD program " verification zone " in the limited DVD playing back.By causing dish in " verification " district to lose efficacy rather than comprise the uniform optical degraded in dvd content district, this preferential inefficacy will prevent that content from degrading before limited DVD playing back expires.

Optical deterioration speed will be subjected to the appreciable impact of sputtered film diffusion barrier thickness subtle change.Rapid variation on the pellumina thickness can obtain by sheltering limited DVD playing back selected " verification " district physically.By using the center sputter mask of 48.0mm diameter, can realize a kind of effective means that preferential broadcast was lost efficacy of effectively obtaining.This sheltering is provided with the ingress area that can cover DVD fully, causes before any content degraded that can watch product the inefficacy of successfully guiding or navigation play menu.Another kind of effectively preferentially play the inefficacy method adopt check field in " derivations " of limited DVD playing back, and the diameter o.d. of reduction sputter mask, described sputter mask is used for being positioned over " derivation " check field physical location inside with mask is radial.

Notice that table provides based on the oxygen dependence of limited Play System of corrosion and the corrosion rate evidence to the MBI concentration dependent.

Embodiment 2. further work shows that reproduction time lost efficacy and greatly depends on the thickness of L0 silver layer.Use by restraining SR415 (Sartomer Company 486, Inc.), 486 gram SR495 (Sartomer), 18.6 gram Irgacure 819 (Ciba SpecialtyChemicals) and 10.0 gram 2-mercaptobenzimidazole (2-MBI, Sigma-Aldrich) bonding agent that is mixed and made into is made the DVD-9 dish with standard DVD grade polycarbonate.The L0 silver thickness of this group dish changes, and it is characterized in that reflectivity values is 16% R14H to 24% R14H.As described in embodiment 1, the manufacturing dish is deposited in it in anaerobic bag, and the anaerobic bag is opened when reproduction time test beginning, and test is carried out on common DVD player.Reproduction time lost efficacy and to measure from coil time of taking out to coiling the hourage that time passed that can not be discerned by DVD player from the anaerobic bag.These results are shown as two kinds of numerical value in following table: last of broadcast hour (coiling last hour of successfully playing)/start first hour (first hour that dish can not be play) of losing efficacy.

Last table shows, thereby the reflectivity of L0 silver layer is strong more thicker, and then Pan reproduction time extends gradually.

The easier oxidation of silver can be owing to the certain characteristics of following combination among the present invention: thin silver-colored L0 coating and the chemical property of mercaptan such as MBI.MBI and silver surface bonding reduced silver-colored redox-potential, makes its easier oxidation by air (Tarasankai Pal, CurrentScience, 83,627-628 (2002)).It is silver-colored compound with the oxidised form that produces also, helps to keep the suboxides electromotive force in the face of concentration of silver ions increase.(G.I.P.Levenson, " The Theory of the Photographic Process 4th Edition " the 15th chapter, T.H.James (ed.), Macmillan publishing Co.Inc., New York, 1977; United States Patent (USP) 5,641,616 reach list of references wherein).In addition, the heterogeneity of Bao silver-colored L0 layer can cause occurring the zone (Pal (2002), people such as Wei Ping Cai, J.Appl.Phys., 83,1705-1710 (1998)) of favourable raising air oxidation.MBI is in the news as antioxidant (Zenovia Moldovan, ActaChim.Slov., 49,909-916 (2002) in the industrial rubber manufacturing; United States Patent (USP) 5,666,994 is incorporated herein by reference its full content at this) and as the reagent (Assouliet.al., Corrosion, 60, the 604-612 (2004) that suppress brass and copper corrosion; Robert B.Faltermeier, Studies in Conservation, 44,121-128 (1999)) this fact supported our following argument: in our system, observes corrosion effect and do not expect.In addition, MBI is used as corrosion inhibitor in the optical medium radiation-hardenable composition.(U.S. Patent application US 2003/0008950 A1 is incorporated herein by reference its full content at this).

The chemical property that is used to prepare the monomer of bonding agent of the present invention and adjuvant has material impact to the corrosion rate of silver layer.Greatly depend on the amount of moisture (water) owing to be well known that the speed of redox reaction in the polymeric media, have been found that introducing absorbent material and monomer are favourable.Particularly, have been found that it is particularly advantageous adopting the monomer of height ethoxylation.The example of these monomers comprises CD9038, has the bisphenol-A of 30 ethylene oxide units; SR415 has the trimethylolpropane triacrylate of 20 ethylene oxide units; SR610, the Macrogol 600 diacrylate; And SR344, PEG400 diacrylate (all can available from Sartomer Co.).When the concentration of ethylene oxide moiety when about 5wt% is increased to up to 80wt%, the cure adhesive that contains MBI shows corrosion rate usually to be increased, thereby the finite lifetime reproduction time is shortened.Preferred oxirane level is for being higher than 50wt%.Also can be separately or be used in combination adjuvant and the monomer that contains other hydrophilic radical such as hydroxyl, carboxyl, acid amides and amine, various salt with other.The tabulation of this hydrophilic segment is not exhaustive, and those skilled in the art can make up the many kinds of polymerizables and the hydrophilic functional groups of polymerizable not, so that the physical strength of balance corrosion rate and limited broadcast dish.

Another kind of control corrosion reaction speed and mode regularly are by adding reductive agent.After optical medium was exposed to atmosphere, these reductive agents will preferentially react with the oxygen that enters at first, exhaust until reductive agent, and at this moment mordant can present activity, causes the reflectivity properties of metal level (one or more layers) destroyed.As other explanation, reductive agent can cause the active corrosion material to exist with lower oxidation state, and this oxidation state is an inertia to reflective metals; After reductive agent exhausted, the mordant precursor was transformed (oxidation) by air, formed corrosion material.Following examples use tetrachloro quinhydrones (TCHQ) as non-corrosive precursor in bonding agent; Be exposed to after the oxygen, TCHQ is oxidized to the benzoquinones form, and its oxidation potential is higher, thereby the ability of oxidation reflection silver layer is stronger.As the corrosion mechanism of other proposition, also may be that the benzoquinones form discharges the known chlorion that causes metal level corrosion in the optical medium.

Embodiment 3. uses reductive agent to be successfully used to silver layer is controlled by tetrachloro quinhydrones (TCHQ) oxidation in the optical medium bonding agent.The DVD-9 dish is made by prescription D and E, and it contains TCHQ separately, and contains the TCHQ that makes up with ascorbic acid.

With dish one week of balance under the situation that does not have air, as indicated above, open then, and be kept in the air of moist chamber, react with accelerated corrosion.As described in embodiment 1, dish is carried out the playability test; Owing to have ascorbic acid, the reproduction time of prescription E increases:

Use ascorbyl palmitate and stannous octoate as reductive agent, observing similar reproduction time increases effect.Many other reductive agents such as U.S. Patent application 10/163,473,10/163,855,10/163,472,10/837,826,10/163,821,10/651,627 and United States Patent (USP) 6,756,103 is described, below all these full patent texts are incorporated herein by reference, and these reductive agents can be applied in the different prescriptions at this, and those skilled in the art can prepare this.

Have been found that stannous octoate is to be used to control the preferred reductive agent based on the limited broadcast timing mechanism that corrodes of the present invention, but it can cause common monomer mixture premature polymerization often unfriendly.For preventing this point, add the polymerization inhibitor such as the quinhydrones of increase level, what make can be formulated as follows the corrosivity bonding agent: it can keep stable viscosity to reach a couple of days in the presence of tin salt.Preferred quinhydrones is 2, and 5-two-amyl hydroquinone (Lowinox AH250, GreatLakes Chemical Corporation, West Lafayette, IN), its working concentration is 0.10wt% to 1.0wt%, preferred 0.2wt% to 0.5wt%.The another kind of compound that shows the monomer formulation viscosity control of success in the presence of tin salt is phenothiazine (the CAS 92-84-2 that uses with the level that is similar to above-mentioned Lowinox AH25; Sigma-AldrichCat.No.P14831).

Another problem of using stannous octoate to cause with the preferred hydrophilic monomer potpourri of above-mentioned time control corrosivity adhesive system is to form vaporific potpourri.Infer that its reason is that tin salt solubleness in the potpourri that mainly contains polyethylene oxide is not good.We have found that, stannous octoate at first is dissolved in tripropylene glycol (TPG, CAS 24800-44-0; Sigma-Aldrich Cat.No.187593) in the time of in, forms clear solution.Owing to estimate that TPG can copolymerization in the bonding agent that solidifies, and may show and do not wish the syneresis that takes place, so, ooze out to observe any possible liquid emphatically testing on to the dish of peeling off under 60 ℃; Fashionablely do not observe syneresis under these conditions or ooze out when TPG adds with the level of cure adhesive 10wt% nearly.

Example 4 explanation even when introducing TPG and depositing in the air, also produces wholesome effect to the high corrosion rate that keeps silver metal layer in the DVD-9 dish under the low humidity condition.Stannous octoate is dissolved in advance among the TPG of different amounts, and merges, make bonding agent G, H and I with stoste F.The bonding agent of gained contains 2.7%-3%MBI, 0.25% stannous octoate, and 0%, the TPG of 5wt% and 10wt%.

Although can being used for providing, the member of the above-mentioned type dyestuff prevents that blue laser from reading the reactive explosive of the coded data of HD-DVD and Blu-ray optical media formats, but have been found that, from being easy to synthetic and the consideration of cost aspect, use 2-arylamino-1, the 4-naphthoquinones is useful especially.The 2-arylamino-1 of being confined to the quinoid ring for the body group, 4-naphthoquinones form that a class (is given body for mono amino) in the 430-500nm scope or near the relatively low (ε of visible band intensity of 550nm place (if having two amino) ^-4000) compound.Substituting group in the aryl rings is influential for common donor-receiver chromophore, and for electrophilic with to electron substituent group, absorption maximum falls into respectively within the scope of 435-560nm.Can also use the 4-arylamino-1 of isomery, the 2-naphthoquinones provides the bigger advantage of absorption intensity (ε=10,000).Under the situation of oxygen (air) for the stimulation that causes optical medium to become can not playing, the reactive colourless colorless form of these compounds is operable, but must prevent that in manufacture process it from too early air oxidation taking place.This can realize that it includes but not limited to ester, silyl ester, carbonic ester, phosphinate, sulphonic acid ester and ether (other leaving group is referring to US 2004/0137188 A1) by multiple blocking groups.The type of blocking groups can be through selecting to provide specific hydrolysis (deblocking) speed, so that manufacture process is controlled.Provide the example of synthetic dyestuffs among Fig. 1-3.The deblocking of protecting group carries out by means of multiple alkaline one-level, secondary and tertiary amine; described amine includes but not limited to, imidazoles, diisopropylamine, lauryl amine, three amylamines, tinuvin 292, amino-hexanol, amino-ethyl morpholine, dihexyl amine, diisobutyl amine, aminoethylpiperazine, amino ethoxy ethanol and dioctylamine.As expected, the hydrophilic/hydrophobic characteristic of adhesive can all have material impact to the deblocking and the air oxidation speed of dyestuff colorless form.Usually, speed is very fast under hydrophilic environment.

For various novel block dyestuffs and in its final application other are had related parameter evaluation, at first make the dish that does not contain the reflection horizon, follow the tracks of the dynamics of deblocking and air oxidation to use UV/ visible spectrometer (VarianCary 50 Scan).Provided below and used general synthetic schemes (embodiment 1/2) to prepare the various derivants of 2-(N-methyl amino phenyl)-1-4-naphthoquinones.This same scheme is used to by using aniline to prepare unmethylated derivant as initiation material.Fig. 4 represents to observe 70 hours then with interior optical disc data in air from making according to guidance.At first, do not absorb in the spectrum visible range, but the leuco dye of deblocking is by complete oxidation after 70 hours, its peak by the 463nm place (absorption peak of 2-(N-methyl amino phenyl)-1-4-naphthoquinones) confirms.Similarly the dish apparatus has the cryovac bag vacuum seal of oxygen scavenger, this section in the identical period in room temperature with under 60 ℃, all keep colourless, this shows from colourless conversion to colored state is that oxygen drives.Fig. 5 shows that the deblocking speed of protected dyestuff depends on used alkali.Therefore by regulating used amine, can design the time limit of deblocking reaction.Similarly, be constant if keep alkali in the adhesive potpourri, change used protected dyestuff, then observe different oxidation (deblocking) speed (seeing Figure 60) that depends on dyestuff and protecting group.Therefore, by regulating used alkali and the blocking groups that is used to protect dyestuff, can provide the limited broadcast dish in broadcast time limit with design.
