Description

Mat surface sheet material with and application thereof

Technical field

The present invention relates to thick in a kind of manufacture for turning into the printing resin original plate of the raw material of flexographic printing version Matte sheet material with resin original plate using its printing with manufacturing flexographic printing version with the manufacture method of resin original plate, by the printing Flexographic printing version manufacture method and using the flexographic printing version liquid crystal display cells manufacture method.

Background technology

Require that thickness is homogeneous as far as possible and nothing to be formed on the electrode forming surface of substrate for constituting liquid crystal display cells Pin hole etc. and the thin high liquid crystal orientation film for applying film quality, and utilize the flexographic printing process with good printing characteristic.

Flexographic printing version can be used in flexographic printing process, the flexographic printing version includes soft resin sheet, and its table Face is contacted with described electrode forming surface etc. in the state of the ink of the raw material as liquid crystal orientation film etc. is carried and is printed Face, and turning into makes the ink offset in the face in the printed face, i.e. version surface.

The ink is kept well for the wetability of ink in order to improve, and can be by the ink kept well The printed face is needed on, the version surface of the flexographic printing version is usually formed as with the coarse of set surface roughness Face.

The manufacture method of following printing resin original plate is recorded in patent document 1：By the piece as the resin The photosensitive polymer combination of the raw material of material (printing resin original plate) is formed as the thick of the die face through mat surface on surface In the state of coating expands to stratiform on matte sheet material, sclerous reaction is carried out using photoactinic irradiation such as ultraviolet Afterwards, mat surface sheet material is peeled off from the sheet material formed by sclerous reaction, thus by mat surface shape transfer in the sheet material The face contacted with the die face, and the face is formed as to the version surface through mat surface.

According to the manufacture method, productibility is good and inexpensive manufacture the entire surface on edition surface through mat surface Printing resin original plate.

As the mat surface sheet material, for example as described in Patent Document 1 as, due to photosensitive polymer combination Compatibility or wetability it is high, so following person etc. can be used：Comprising the mat surface shape of die face can be needed on into print well The carbamate based thermoplastic elastomer (thermoplastic polyurethanes on the version surface of brush resin original plate (thermoplastic polyurethane, TPU)) sheet material, and with the die face side be opposite surface layer pressure for example gather PETP (polyethyleneterephthalate, PET) film etc. is used as enhancing film person.

The mat surface sheet material can for example be manufactured in the following way：By TPU extrusion moldings be sheet, and with increasing Strong film is continuously inserted in mat surface roller and to after between roller, optionally cutting as set size, the mat surface together The outer peripheral face of roller is formed as the model face of mat surface shape corresponding with the mat surface shape of the die face of mat surface sheet material.

That is, by the pressure during insertion, TPU sheet material is laminated each other with enhancing film, and the model face is thick Matte shape transfer is in the surface of the sheet material, and the surface is formed as the die face through mat surface.

But, in the existing mat surface sheet material, when synthesizing TPU, produce the partial gel for being referred to as flake Shape thing, if the flake is held in and strengthened between film and local projection is produced in die face, has in printing resinogen The problem of version surface of version produces be recessed corresponding with the projection and damages the flatness on this edition surface.

For in terms of TPU synthesis mechanism, flake is difficult to complete removal, and after lamination, the mat surface before cutting Sheet material includes a large amount of flakes certainly.

Therefore, when manufacturing mat surface sheet material, it is necessary to which after the position that flake is produced is confirmed, selection cuts flake not The region of generation, the waste of material becomes many.

In addition, it is same composition to form the partial gel shape thing of flake substantially with TPU, due to color and luster or outward appearance almost phase Together, so needing substantial amounts of labour in terms of location confirmation in described cut or the inspection of the mat surface sheet material after cutting With the time.

Therefore, these situations are combined with each other and there is the problem of productivity of coarse facesheet is reduced.

If in addition, the mat surface sheet material that flake is leaked through in inspection for example to be used for into the manufacture of printing resin original plate In, it is likely that produce depression on version surface as described above and produce the defective products being not used in printing, so that the printing Risen with the fraction defective of resin original plate and then flexographic printing version, productivity reduction, the productivity of final liquid crystal display cells also drops It is low.

Embodiment

Fig. 1 is the profile that the layer of one of the embodiment of the mat surface sheet material of the present invention is constituted to enlarged representation. In addition, Fig. 2 is to one that manufactures the process of the mat surface sheet material of Fig. 1 figure illustrated.

Reference picture 1, the mat surface sheet material 1 of this is the one side (being upper surface in figure) in the PET film as enhancing film 2 Sequentially lamination intermediate layer 3 and the top layer 4 comprising TPU are formed, and the surface exposed on the top layer 4 is formed as through mat surface Die face 5.

In reference picture 2, the manufacture method of the mat surface sheet material 1 of this, first, the original in intermediate layer 3 and top layer 4 is become Two kinds of molten resins of material by be connected to the mould 6 of two layers of extrusion of two extruderses (not shown) and respectively with sheet and With the state continuously extrusion molding being stacked on one another.

Then, the enhancing film intermediate layer 3 before cooling and solidifying continuously supplied with the layered product on top layer 4 and with strip 2 are continuously inserted in as shown in the arrow of double dot dash line in figure mat surface roller 7 and between roller 8 respectively together.Now, table The surface (face in figure for right side) exposed of layer 4 connects with mat surface roller 7.

On mat surface roller 7, including its outer peripheral face outermost layer 9 for example comprising silicone rubber, and the outer peripheral face shape The model face 10 of the corresponding mat surface shape of mat surface (die face 5) as the surface with being formed at top layer 4.

On mat surface roller 7, set pressure rolling pressure is applied towards the direction to roller 8 as shown in white arrow in figure, and The surface on the right side being crimped in the figure on top layer 4.

In addition, to roller 8 in addition to as the backing roll function for the crimping, also serving as although not shown but wrapping Include the chill roll function of cooling body, the chill roll to cool down intermediate layer 3, top layer 4 and solidify it.

Therefore, by being inserted between two roller 7, roller 8, and top layer 4, intermediate layer 3 and enhancing film 2 are integratedly laminated, And the mat surface shape in the model face 10 of mat surface roller 7 is continuously transferred on the surface on the top layer 4, so as to continuously make Make the surface and be formed as the mat surface sheet material 1 die face 5, being constituted with the layer shown in Fig. 1 through mat surface.

Manufactured mat surface sheet material 1 and then certain length etc. is optionally cut into, so that for printing resinogen In the manufacture of version.

Top layer 4 in the mat surface sheet material 1 can be formed by TPU in the same manner as in the past.

As TPU, the TPU of ester type or ether type can be enumerated, wherein, the preferably TPU of ester type.

As the TPU of ester type, for example, it is preferably that selection uses DIC Cohan wound polymer (DIC Covestro Especially having in the TPU for spandex (PANDEX) (registration mark) T series that Polymer) (stock) is manufactured is photoactinic Permeability person.

Intermediate layer 3 can be by with for forming the TPU on the top layer 4 and being removed as the compatibility of the PET film of enhancing film 2 (except TPU) thermoplastic elastomer (TPE) beyond TPU is formed.

As the thermoplastic elastomer (TPE), a variety of thermoplastic elastics in addition to TPU with the function can be used Body.

That is, as thermoplastic elastomer (TPE), for example, it can enumerate selected from by olefin series thermoplastic elastomer, polystyrene thermoplasticity At least one of group that elastomer, Polyester thermoplastic elastomer (TPE) and Thermoplastic polyamide elastomer are constituted, it is special excellent Elect olefin series thermoplastic elastomer as.

In addition, as olefin series thermoplastic elastomer, such as can enumerate：Ethene based thermoplastic elastomer, propylene thermoplastic Property elastomer etc..Wherein, preferably propylene-based thermoplastic's elastomer, particularly preferably for selected from α-alkene in addition to ethene and propylene The monomer of one or more of hydrocarbon and the random copolymer of propylene or block copolymer.

As the alpha-olefin in addition to ethene and propylene, for example, it can enumerate butylene, amylene, hexene, heptene, octene, the last of the ten Heavenly stems At least one of alkene, laurylene etc..

As the concrete example of propylene-based thermoplastic's elastomer, the crystalline portion that can for example enumerate in molecule with it is noncrystalline The part Mitsui Chemicals that heat resistance, flexibility, photoactinic permeability etc. are improved with nanoscale progress structure control Propylene-based thermoplastic's elastomer of Ta Fuma (TAFMER) (registration mark) PN series of (stock) manufacture.

The intermediate layer 3 comprising thermoplastic elastomer (TPE) in order to the top layer 4 and enhancing film 2 is good ground integrated, and By being situated between every being present between the top layer 4 and enhancing film 2, to reduce the thickness on top layer 4 in the gross thickness of mat surface sheet material 1 Shared ratio and function.

That is, by the way that a part for the thickness of the TPU of existing mat surface sheet material layer is replaced into the intermediate layer 3, The thickness on the top layer 4 comprising TPU can be reduced and the usage amount for the TPU to form the top layer 4 is reduced, so that the amount of flake is reduced, and The generation number of projection caused by the flake can be suppressed.

Therefore, the ratio in the region for not producing flake can be increased compared with present situation, and reduce the waste of material when cutting, and Location confirmation when can cut down described cut or the labour needed for the inspection of the mat surface sheet material after cutting and time, as As a result the productivity of mat surface sheet material 1 can be improved.

Strengthen film 2 except with the increasing as literal as the overall tensile strength for improving mat surface sheet material 1 etc. Beyond strong function, be alternatively the correction mat surface sheet material 1 warpage and function.

That is, if omitting enhancing film 2, and only by the thermoplastic elastomer (TPE) of the raw material as intermediate layer 3 with turning into top layer 4 The TPU of raw material extrusion moldings simultaneously are simultaneously laminated each other, it is likely that the difference of the shrinkage factor based on two elastomers, in mat surface The big side of intermediate layer 3 of sheet material, especially shrinkage factor produces the warpage (mountain warpage) of depression, made thereby using the mat surface sheet material The flatness reduction on the version surface for the printing resin original plate made.

On the other hand, if the opposing face lamination in the intermediate layer 3 strengthens film 2, the warpage can be suppressed and produced.

As enhancing film 2, can as described above as use PET film.It is particularly preferably the PET with photoactinic permeability Film.

PET film as enhanced function or correct warpage function etc. it is excellent and also excellent with TPU compatibility.

In each layer, the thickness on top layer 4 is preferably more than 0.01mm, below 0.06mm.

By the extrusion molding by thickness less than the top layer 4 and then the top layer 4 of the scope and the layer in intermediate layer 3 Stack is successfully shaped to sheet and is not easy to, and is possible to produce uneven thickness or resin fracture etc..

On the other hand, in the case where the thickness on top layer 4 exceedes the scope, it is possible to can not fully obtain following effect Really：As described by being situated between every there is intermediate layer 3, and reduce the thickness on top layer 4, so as to suppress the generation of flake.

On the other hand, by the way that the thickness on top layer 4 is set into the scope, good mouldability can be maintained, while more practical Ground suppresses the generation of flake.

In order to reduce the thickness on top layer 4 as described above, the thickness in intermediate layer 3 is preferably greater than the thickness on the top layer 4, special Preferably more than 0.07mm, below 0.20mm.

By the extrusion molding by thickness less than intermediate layer 3 and then the intermediate layer 3 and the top layer 4 of the scope Layered product is successfully shaped to sheet and is not easy to, and is possible to produce uneven thickness or resin fracture etc..

In addition, though also depending on the thickness on top layer 4, but the coarse of model face 10 is transferred using the manufacture method Two layers of aggregate thickness of face shape diminishes, and it is also possible to the mat surface shape can not be fully reproduced in into die face 5.

And then, although the thickness on top layer 4 is also depended on, but mat surface sheet material 1 becomes easy bending, if producing curved Defect (bending defect) is produced in folding, then the mat surface shape for being also possible to the version surface in die face 5 and then flexographic printing version, So as to produce the problem of for example can not forming homogeneous thickness and continuous liquid crystal orientation film.

On the other hand, in the case where the thickness in intermediate layer 3 exceedes the scope, although also depend on the thickness on top layer 4, But the increase of the weight of mat surface sheet material 1, and become to be difficult to that the mat surface sheet material 1 is bent or crimped, it is therefore possible to For example batch the strip mat surface sheet material 1 before shearing or be used to print by the mat surface sheet material 1 sheared and manufactured and use In the manufacture of resin original plate or in order to carry out the reduction such as treatability during the processing stored etc. and be wound.

On the other hand, by the way that the thickness in intermediate layer 3 is set into the scope, good mouldability can be maintained, while conscientiously Ground suppresses the various problems and produced.

If situation in view of improving the treatability etc. etc., the gross thickness of mat surface sheet material 1 is preferably 0.45mm Below.

In addition, therefore, the upper limit of top layer 4 and the aggregate thickness in intermediate layer 3 is preferably to be set as by the upper of the gross thickness Limit is subtracted obtained by the thickness of enhancing film 2 below thickness.

The thickness for strengthening film 2 is preferably more than 0.05mm, preferably below 0.19mm.

If thickness is less than the scope, in described processing etc., strengthens film 2 and then mat surface sheet material 1 becomes easily curved Folding, if producing bending, it is likely that produce bending in the mat surface shape on die face 5 and then the version surface of flexographic printing version and lack Fall into, so as to produce the problem of for example can not forming homogeneous thickness and continuous liquid crystal orientation film.

In addition, causing the effect for correcting the warpage to become insufficient because setting enhancing film 2, so as to be also possible to use The flatness reduction on the version surface of the printing resin original plate manufactured by mat surface sheet material 1.

On the other hand, in the case where the thickness of enhancing film 2 exceedes the scope, the weight increase of mat surface sheet material 1, And become to be difficult to that the mat surface sheet material 1 is bent or crimped, it is therefore possible to the reduction such as described treatability.

On the other hand, by the way that the thickness for strengthening film 2 is set into the scope, and the generation of bending can be suppressed as far as possible, together Treatability of Shi Tigao mat surface sheet materials etc..

Furthermore, if the generation in view of further suppressing bending well, strengthen the thickness of film 2 in the scope Preferably more than 0.10mm.

Fig. 3 (a)~Fig. 3 (c) is to represent the mat surface sheet material using Fig. 1, is made using the manufacture method of the present invention Make the profile of one of the process of printing resin original plate.In addition, Fig. 4 (a)~Fig. 4 (c) is to represent Fig. 3 (a)~Fig. 3 (c) Subsequent handling the profile of one.

Reference picture 3 (a), in the manufacture method of the printing resin original plate of this, first, prepares glass or includes propylene The hard such as the hard resins such as acid resin, polycarbonate resin, polyester resin have photoactinic permeabilities such as ultraviolet in addition Material supporting substrate 11.

Then, it is upper, work using the die face 5 on the surface as top layer 4 in the figure of supporting substrate 11 on the surface 12 of upside Mode under being for the opposing face 13 that strengthens the surface of film 2, while the opposing face 13 is contacted with the surface 12 of supporting substrate 11, On one side enhancing film 2, intermediate layer 3 and this three layers present invention of top layer 4 will be included for example as shown in a dashdotted arrow in figure Mat surface sheet material 1 from the one end on the surface 12 to the other end sequentially overlapping grade and load and unload freely fix.

On mat surface sheet material 1, in order to extend the photoresist of liquid by being coated with the mat surface sheet material 1 Convergent force during hardening of cut-out power or photosensitive polymer combination during composition etc. and prevent relative to supporting substrate 11 And position is offset, and the exchange of the mat surface sheet material 1 after use becomes easy, be preferably for example by following (i)~ (iii) either method is detachably fixed on the surface 12 of supporting substrate 11.

(i) it is solid via detachably being adhered comprising the weak adhesion coating with the material for photoactinic permeability It is fixed.

(ii) filled by forming attraction groove on the surface 12 of supporting substrate 11 and carrying out vacuum attraction via the attraction groove Absorption freely is unloaded to fix.

(iii) to be prolonged between a pair of collet fixtures of the size greater distance for separating the face direction compared with supporting substrate 11 The state of exhibition detachably crimps fixation.

Wherein, the weak adhesion coating as the adhesion for (i) in fixed, the layer comprising a variety of stickers any one Using, the sticker has weak adherence for supporting substrate 11 and as the PET film of enhancing film 2, and with for light Change the permeability of ray.Weak adhesion coating can be formed in the following manner：Come for example, by a variety of coating methods such as spraying coating The sticker is coated at least one of the surface 12 of supporting substrate 11 and the opposing face 13 of mat surface sheet material 1.

Formed after the weak adhesion coating, while noting the table not admitted air into mat surface sheet material and supporting substrate 11 Between face 12, while with opposing face 13 for it is lower and as shown in a dashdotted arrow in Fig. 3 (a) by mat surface sheet material 1 from The one end on the surface 12 of supporting substrate 11 to the other end it is sequentially overlapping after, the adhesion strength that mat surface sheet material 1 passes through weak adhesion coating And be fixed on surface 12.

In addition, in order to which the mat surface fixed sheet material 1 is unloaded from surface 12, as long as while resisting the viscous of weak adhesion coating Put forth effort, the arrow for example with Fig. 3 (a) sequentially peels the mat surface off to one end from the other end of supporting substrate 11 on the contrary on one side Sheet material 1.

In order to which the absorption for carrying out (ii) is fixed, the surface 12 of supporting substrate 11 is finished to be smooth, and in the table The substantially entire surface formation in face 12 attracts groove.Groove is attracted to be connected to the vacuum system for including vavuum pump etc..

Then, with the state on mat surface sheet material 1 is overlapped in supporting substrate 11 surface 12 to be lower of opposing face 13 Under make vacuum system operate or by the vacuum system operated in advance with attracting groove to be connected etc. via attraction groove progress vacuum After attraction, mat surface sheet material 1 is fixed on surface 12.
