Detailed Description
The best mode for carrying out the present invention (hereinafter, simply referred to as "embodiment") will be described in detail below. The present invention is not limited to the following embodiments, and can be implemented by being variously modified within the scope of the gist thereof.
The photosensitive resin laminate roll is a photosensitive resin laminate roll in which a long (strip-shaped) photosensitive resin laminate is wound around a core in the longitudinal direction thereof, and a roll end surface protection member is disposed so as to be in contact with the end surface of the wound photosensitive resin laminate (the end portion side in the width direction of the strip-shaped photosensitive resin laminate).
Fig. 1 is a schematic view of an embodiment of such a photosensitive resin laminate roll 10. Here, the photosensitive resin laminate 1 includes a support layer 4, a photosensitive resin layer 5 laminated on the support layer, and an optional protective layer 6, and the laminate 1 is wound around a core 2. Further, end-face-winding protection members 3 are provided in contact with both end faces of the wound photosensitive resin laminate. Here, the roll end face protection member 3 is shown as an annular sheet.
(photosensitive resin laminate)
The photosensitive resin laminate includes at least a support layer and a photosensitive resin layer laminated on the support layer, and preferably further includes a protective layer laminated on the photosensitive resin layer. The photosensitive resin laminate further includes a photosensitive film called a dry film resist or a dry film photoresist.
The support layer may be of any structure as long as it supports the photosensitive resin layer. As the support layer that can be used, a transparent layer that transmits light emitted from an exposure light source is preferable. Examples of such a support layer include a polyethylene terephthalate film, a polyvinyl alcohol film, a polyvinyl chloride film, a vinyl chloride copolymer film, a polyvinylidene chloride film, a vinylidene chloride copolymer film, a polymethyl methacrylate copolymer film, a polystyrene film, a polyacrylonitrile film, a styrene copolymer film, a polyamide film, and a cellulose derivative film. These films may be used after being stretched as required. From the viewpoint of resolution, a film having a haze of 5 or less is preferable. The haze is more preferably 3 or less, still more preferably 2.5 or less, and still more preferably 1 or less. The thickness of the support layer is preferably 10 μm to 30 μm, although a thin layer is advantageous in terms of image formability and economy, since it is necessary to maintain thermal shrinkage when the photosensitive resin composition layer is applied. Examples thereof include GR19, GR16 manufactured by DuPont film (strain), R310-16 manufactured by Mitsubishi Plastics, Inc., R340G16 manufactured by Mitsubishi Plastics, FB40(16 μm film thickness) manufactured by Bao レポリエステルフィルム (strain), FB60(16 μm film thickness), and the like.
The protective layer is sufficiently smaller in adhesion force with the photosensitive resin layer than the support layer, and therefore can be easily peeled off. For example, as the protective layer, a polyethylene film, a polypropylene film, a stretched polypropylene film, or the like can be preferably used. Further, a film excellent in releasability disclosed in Japanese patent application laid-open No. 59-202457 can be used. The thickness of the protective layer is preferably 10 to 100 μm, and more preferably 10 to 50 μm. Examples thereof include GF-18, GF-818 and GF-858 manufactured by Tamapoly Co., Ltd.
The photosensitive resin layer can be laminated by applying a photosensitive resin composition to a support layer and drying the applied composition. The thickness of the photosensitive resin layer is preferably 5 to 100 μm, and the upper limit is more preferably 50 μm. The thickness of the photosensitive resin layer is appropriately selected according to the application because the resolution is improved as the thickness approaches 5 μm, and the film strength is improved as the thickness approaches 100 μm.
As a method for producing the photosensitive resin laminate, a conventionally known method can be employed. For example, a photosensitive resin composition used for a photosensitive resin layer is mixed with a solvent as a photosensitive resin composition mixed solution, and the mixture is applied to a support layer using a bar coater or a roll coater and dried, and a photosensitive resin layer containing the photosensitive resin composition is laminated on the support layer. The photosensitive resin composition mixture liquid is preferably mixed with a solvent to a temperature of 500 to 4000 mPa.s at 25 ℃. From the viewpoint of the viscosity, drying property, residual solvent amount, coating property and foaming property of the photosensitive resin composition preparation solution, methyl ethyl ketone, acetone, ethanol, methanol, propanol, propylene glycol monomethyl ether acetate, toluene and the like can be used as appropriate as the solvent. Next, a protective layer is laminated on the photosensitive resin layer, whereby a photosensitive resin laminate can be produced.
The photosensitive resin laminate is used in a roll form by being wound around a core in a long shape. The winding length is not particularly limited, and is preferably 320m or less from the viewpoint of the weight of the roll and the ease of handling. The more substrates can be rolled up from the 1 photosensitive resin laminate, the higher the efficiency, and therefore, from the viewpoint of productivity, the winding length is preferably 100m or more.
(roll core)
Winding cores are sometimes also referred to as cores. The shape is not particularly limited, and may be cylindrical or columnar. Since the photosensitive resin laminate is used for an electronic material as an etching or plating resist and a permanent pattern, a winding core subjected to dust-free treatment is preferable, and a winding core made of a plastic resin is preferable. The plastic resin is preferably light, high in strength, and dust-free. Polypropylene (PP) resin, acrylonitrile-butadiene-styrene (ABS) resin, nylon resin, polyvinyl chloride resin, etc. can be used, with ABS resin being preferred. The diameter of the core is not particularly limited, and when the photosensitive resin laminate is wound and mounted in a laminating apparatus, the core preferably has a diameter of 2 to 5 inches, more preferably 3 inches, so as to be mounted in the apparatus. The length of the core (axial length when a cylindrical or columnar core is used) may be the same as or shorter than the width of the photosensitive resin laminate, but when the photosensitive resin laminate is wound, the length of the core is preferably longer than the width of the photosensitive resin laminate so that appropriate protruding portions can be secured on both sides. It is preferable that the annular sheet is attached so as to penetrate the protruding portion. Further, a bearing called a core holder may be fitted to the protruding portion to store the photosensitive resin laminate roll in a suspended state so that the photosensitive resin laminate roll does not move.
(roll end face protection member)
The roll end face protection member is disposed so as to be in contact with the end face of the wound photosensitive resin laminate. The shape is not particularly limited, and is not particularly limited as long as the end face is in contact with a certain area and at least a part of the roll end face is covered and protected, and among these, an annular sheet is preferably disposed so as to penetrate the protruding portion of the core so as to be in contact with the end face of the wound photosensitive resin laminate. More preferably, the photosensitive resin laminate roll end surface is formed into a ring shape having a width that can substantially cover the entire photosensitive resin laminate roll end surface. The roll end face protection member may be used only at one end of the wound photosensitive resin laminate, but is preferably used at both ends.
When the roll end surface protecting member is an annular sheet, the inner diameter of the ring is preferably slightly larger than the outer diameter of the core so that the ring can penetrate the core.

(examples 1 to 12, comparative example 1)
1. Preparation of evaluation sample
The evaluation samples in examples and comparative examples were prepared as follows.
< production of photosensitive resin laminate >
A photosensitive resin composition blend liquid was prepared by sufficiently stirring and mixing a composition 1 shown in table 1 below (wherein the number of each component represents the amount (parts by mass) of solid components, the abbreviation of which is shown in table 1 corresponds to that of table 2) and a solvent, and a 16 μm-thick polyethylene terephthalate film (R310 manufactured by Mitsubishi Plastics, inc.) was prepared as a support, and the photosensitive resin composition blend liquid was uniformly applied to the surface of the polyethylene terephthalate film by a die coater and dried, followed by forming a photosensitive resin layer. The thickness of the photosensitive resin layer was 15 μm. Next, a polyethylene film (GF-858, manufactured by ltd., TAMAPOLY co., ltd.) having a thickness of 33 μm was laminated as a protective layer on the surface of the photosensitive resin layer on which the polyethylene terephthalate film was not laminated, to obtain a photosensitive resin laminate 1.
Photosensitive resin laminates 2 to 6 were obtained in the same manner as the photosensitive resin laminate 1 except that the composition 1 was changed to compositions 2 to 6 in the photosensitive resin laminate 1. The photosensitive resin laminate 1 was produced in the same manner as the photosensitive resin laminate 1 except that the composition 1 was 7 to 10 and the thickness of the photosensitive resin layer was 10 μm, to obtain photosensitive resin laminates 7 to 10.
< production of photosensitive resin laminate roll >
The sheets shown in tables 3 to 5 were used as the endless sheet. For the pressure-sensitive adhesive composition containing an acrylic resin for a cyclic sheet, an adhesive composition obtained by direct use of Elleair TackNS80/SBG 85S/removability (manufactured by Elleair Texel Co., Ltd.) will be used unless otherwise specified.
For samples F and G, the adhesive compositions were adjusted as follows. That is, B-1 and M-8 shown in Table 2 were compounded so that the solid content ratio was 45:55 and 40:60, and the mixture was applied to a substrate, dried and adjusted so that the film thickness after drying was 15 μ M.
The photosensitive resin laminate 1 was cut to have a width of 495mm, and wound around an ABS resin core (core body) having an inner diameter of 77mm, an outer diameter of 88mm and a length of 530mm for 300 m. The photosensitive resin laminate wound in a roll shape had an outer diameter of 180 mm.
The photosensitive resin laminate wound around the core in a roll shape is held by a rod-shaped stainless steel holder, and the rod-shaped stainless steel holder is designed so that the other end thereof is fixed to be able to be held horizontally.
The photosensitive resin laminate was wound into a roll and covered with a cylindrical light-shielding polyethylene tube having an outer circumference of 500mm, a length of 800mm and a thickness of 80 μm.
The photosensitive resin laminate in a roll form covered with the light-shielding polyethylene tube was removed from the holder, and a roll was placed on a buffer section which was designed to have a width of 330mm and a height of 100mm and an upper portion which was curved in a concave shape so that the roll could be fixed.
One end of the light-shielding polyethylene tube is folded back to expose the end face of the rolled photosensitive resin laminate, and an annular sheet is attached. Similarly, the other end was attached with an annular sheet, and a photosensitive resin laminate roll 1 was produced.
The photosensitive resin roll 1 is packaged by folding a light-shielding polyethylene tube into a core, attaching a core holder designed so that the center portion thereof is convex and the core fits into the core.
2. Evaluation criteria
The photosensitive resin laminate roll was evaluated and rated according to the following evaluation items and evaluation criteria. The evaluation results are shown in tables 3 to 5.
(1) Removing property of foreign matter
The annular sheet was peeled from the photosensitive resin laminate roll, and it was confirmed whether or not foreign matter was attached to the annular sheet. The rating is done as follows.
○ foreign matter was attached to the annular sheet, and another adhesive tape was attached to the end face of the roll and peeled off, and no foreign matter was observed.
△ foreign matter was attached to the annular sheet, but when another adhesive tape was attached to the end face of the roll and peeled off, it was confirmed that foreign matter was also attached to the adhesive tape.
X: foreign matter is not attached to the annular sheet. When another adhesive tape was attached to the end face of the roll and peeled off, it was confirmed that foreign matter was attached.
(2) Loop sheet mountability
The roll was produced as described in the above-mentioned item < production of photosensitive resin laminate roll > and the mountability of the annular film at the end face of the roll was rated as follows.
○ the ring-shaped sheet can be simply mounted and attached to the end face of the roll without wrinkles.
△ time is required to attach and mount the loop sheet to the holder or core some of the wrinkles or air is introduced into the end of the roll.
X: the attachment and mounting of the annular sheet to the holder or the winding core requires time. When the annular sheet attached to the undesired portion is peeled off and attached again, the annular sheet is stretched and deformed or broken, and attachment to the roll end face becomes difficult.
(3) Wrapping material adhesiveness of annular sheet
After the roll was produced as described in the above-mentioned < production of photosensitive resin laminate roll > and was unsealed. After the unsealing, whether or not the annular sheet was attached to the end face was also observed in the same manner as in the attachment, and the grade was given as follows.
○, the installation is the same as the installation.
△ the ring-shaped sheet is stuck to the light-shielding cylindrical polyethylene sheet at the time of unsealing and has a part peeled from a part of the end face.
X: the ring-shaped sheet is adhered to the light-shielding cylindrical polyethylene sheet during unsealing, and is peeled off together with the light-shielding cylindrical polyethylene sheet.
(4) Removability of endless sheet
After the roll was produced as described in the above-mentioned < production of photosensitive resin laminate roll > and the roll was unsealed, the ring-shaped sheet was peeled off by a hand wearing a resin glove. The operability at the time of peeling was rated as follows.
○ the loop sheet can be easily peeled off within 5 seconds.
△ peeling of the loop sheet takes 5 seconds or more.
(5) Number of foreign matters
The photosensitive resin laminate roll of 14 rolls was produced as described in the above section < production of photosensitive resin laminate roll >. Foreign matter was removed from the end faces of all the rolls, and the foreign matter was randomly attached to the total of four positions of the roll end faces from the 14 rolls. After that, the annular sheet was attached and peeled off to all the rolls, and foreign matter adhering to the roll end face was calculated.
