The specific embodiment
Below, embodiments of the present invention are described in detail.
The example that film of the present invention is formed with resin relief is illustrated.The integral body of resin relief 1 has the quadrangle shape as shown in Figure 1, is provided with printing protuberance 2 in the central.Like this, as shown in Figures 2 and 3, distributing on protuberance 2 whole surfaces in above-mentioned printing forms a plurality of microspikes 3, is formed with the slot part 4 that is used to keep form the coating liquid of oriented film between adjacent microspike 3.Above-mentioned printing is with on the middle section X of protuberance 2, and adjacent microspike 3 equally spaced forms.On the other hand, above-mentioned printing is with on the neighboring area Y of protuberance 2, and the distribution density of microspike 3 is bigger than middle section X, simultaneously on the Y of neighboring area along with towards the end and the area ratio/occupancy ratio of microspike 3 increases gradually.In addition, the area ratio/occupancy ratio of this microspike 3 is meant shared ratio in the gross area of the slot part 4 that microspike 3 forms between by microspike 3 and above-mentioned adjacent microspike 3.
Film of the present invention forms with resin relief 1 all same as the prior art on shape, material and using method etc.That is, the basic structure of this resin relief 1 is to be made of with the non-2a of Printing Department of this printing of supporting with protuberance 2 with protuberance 2 printing that light-cured resin is solidify to form.On the surface of this printing, apply the coating of liquid then, will apply the liquid transfer printing and be printed on the body with protuberance 2.
Above-mentioned printing can suitably determine with the flat shape of protuberance 2, but adopt roughly quadrangle more usually.Therefore, in the present invention, be under the tetragonal situation with protuberance 2 in printing, above-mentioned printing is called each periphery on four limits of quadrangle with the neighboring area Y of protuberance 2.
Above-mentioned printing can be according to the suitably settings such as size of its resin relief 1 integral body with the scope of the neighboring area Y of protuberance 2, but typically refer to apart from the medial region scope of printing with the circumference 0.1～number millimeter of protuberance 2, the preferably medial region about 0.1～1mm.In addition, aforesaid Fig. 1 (a) is the accompanying drawing that schematically illustrates the plane of its resin relief 1, for the middle section X of protuberance 2, has represented neighboring area Y with respect to printing significantly, but in fact neighboring area Y and middle section X to compare its area very little.
Above-mentioned printing is set distribution density greater than the microspike 3 at middle section X place for the distribution density of the microspike 3 among the neighboring area Y of protuberance 2.Specifically, it is 1.2～2.5 with the distribution density (Y) of the microspike 3 at the Y place, neighboring area of protuberance 2 and the ratio [(Y)/(X)] that prints with the distribution density (X) of the microspike 3 at the middle section X place of protuberance 2 that its degree is preferably set printing for, (Y)/(X)=1.3～2.3 item better.Promptly, if (Y)/(X) less than 1.2, then lack the effect that prevents that marginal phenomena from taking place, and when surpassing 2.5, then keep slot part 4 degree of depth (the degree of depth) of the coating liquid between the microspike 3 insufficient from microspike 3 surfaces, broken off being trapped in the path of printing with the remaining coating liquid flow direction outside on protuberance 2 middle bodies, the result causes oriented film bad.
In addition, on the Y of the neighboring area of the distribution density of setting microspike 3 significantly, set its neighboring area Y for and go up along with towards the end and the area ratio/occupancy ratio of microspike 3 increases gradually.Above-mentioned " area ratio/occupancy ratio of microspike 3 increases gradually " be meant set for go up near the area ratio/occupancy ratio of the microspike the middle section X 3 to the area ratio/occupancy ratio of the microspike 3 of end one side of neighboring area Y from printing with the neighboring area Y of protuberance 2 till, the value stage ground of its area occupation ratio increases.Then, as the degree that its area ratio/occupancy ratio increases, preferably setting printing for is 1.1～3.3 with near the ratio [(α)/(β)] of the area ratio/occupancy ratio (β) of the microspike 3 of the area ratio/occupancy ratio (α) of the microspike 3 of Y upper end, neighboring area one side of protuberance 2 and middle section X.
In the present invention, there is no particular limitation to printing the degree of depth of using the slot part 4 that forms on the protuberance 2, can on printing, form roughly certain depth with protuberance 2, for example, normally set in printing with on the middle section X of protuberance 2, the degree of depth of the slot part 4 that is formed by a plurality of microspikes 3 is roughly certain, and on the Y of neighboring area from one side shoals gradually towards the end near the middle section X.
The mutual interval of above-mentioned microspike 3 and the degree of depth of slot part 4 are limited especially, but appropriate depth.That is, the thickness of the oriented film that can form according to transfer printing, printing is suitably set.For example, if the thickness of oriented film is 300～1000 Izod right sides, then as long as microspike 3 mutual intervals are in the scope about 0.03～0.1mm.And as long as the degree of depth of slot part 4 is in the scope about 0.002～0.035mm.
And it is round platform or cylindric that above-mentioned microspike 3 is normally made the cross section.Like this, with respect to printing for the protrusion diameter of the microspike 3 on the protuberance 2 middle section X, the protrusion diameter that printing is preferably set near the microspike the middle section X 3 with the protrusion diameter of the microspike 3 on the protuberance 2 neighboring area Y is more than 0.3 times, less than 1.5 times, and the protrusion diameter of Y end, neighboring area one side microspike 3 is more than 1.5 times, less than 3.0 times.The protrusion diameter that is more preferably near the microspike 3 of middle section X is more than 0.9 times, less than 1.3 times, and the protrusion diameter of the microspike 3 of Y end, neighboring area one side is more than 1.6 times, less than 2.4 times.Promptly, protrusion diameter by such setting microspike 3, when adopting resin relief 1 on printing machine, to print oriented film, can obtain to apply liquid under the effect of the squeegee pressure that applies in the rotation of printing machine version tube and can not be detained in a certain direction and make it in the homodisperse on the whole effect of protuberance.
About at the Pareto diagram of printing, preferably be arranged in Pareto diagram that neighboring area Y goes up the microspike 3 that forms and be 0～45 with respect to the Pareto diagram of the last formation of middle section X with the microspike 3 that forms on the protuberance 2.It is then better to be 0～30 ° of angle.
Film of the present invention forms and for example can be made as follows with resin relief.That is, at first, on the resin relief corresponding to printing with on the zone of protuberance, prepare with the corresponding part of microspike be transparent, with corresponding part of slot part and printing be the minus film of black with the zone (non-printing zone) beyond the protuberance.Then, the certain thickness aqueous light-cured resin of coating forms aqueous light-cured resin layer on this minus film.After forming layer, stacked hyaline membrane (basement membrane) on above-mentioned aqueous light-cured resin layer carries out illumination via this hyaline membrane afterwards, and above-mentioned aqueous light-cured resin is solidified, and makes the non-Printing Department of resin relief.Then,, form the printing protuberance of resin relief, simultaneously the slot part that on this prints with protuberance, forms a plurality of microspikes and be provided with by this microspike by carrying out illumination via above-mentioned minus film.Then, with uncured resin clean remove after, can make resin relief by drying and exposure light irradiation (post-exposure).
In addition, form as film of the present invention and use resin relief, also can adopt stacking gradually the relief printing plate of bond layer, metallic plate or the synthetic resin board of formations such as base membrane layer, pressure-sensitive type bonding agent on formation face opposing face (back side) side with the printing of the resin relief of above-mentioned such acquisition.By adopting the resin relief of such formation, cup-shaped phenomenon (phenomenon that the printing of relief printing plate material itself uses the thickness of the neighboring area of protuberance to form than the middle section heavy back) is difficult for producing, and the result can suppress the generation of marginal phenomena effectively.
As above-mentioned aqueous light-cured resin, so long as knownly in the past then do not limit especially in addition, for example, resins such as light sensitizer or heat stabilizer have been added in use in unsaturated polyester resin or polybutadiene etc., or have added the resin of light sensitizer or heat stabilizer in prepolymers such as acrylic, urethanes, oxo group, polyester have imported the unsaturated-resin of unsaturated group.In addition,, be not limited in as described above aqueously, also can be tabular such resin of representing solid as light-cured resin.Specifically, can list APR (Asahi Chemical Industry's corporate system), AFP (Asahi Chemical Industry's corporate system) or テ PVC ス (Supreme Being people's corporate system) etc.
Form with the pattern of printing on the resin relief for film of the present invention and to form, the corresponding transparent part of microspike that can be by suitable adjustment and above-mentioned minus film and partly form the pattern of desirable microspike with the corresponding black of slot part with the microspike of the feature of protuberance.This minus film can adopt the desirable pattern of the integrated machine of image formation such as (image processing apparatus) of the exposure of film for example usefulness and make.
Adopting the film that obtains like this to form the oriented film that forms as film with resin relief can be undertaken by following.That is, carry out oriented film on protuberance in the printing of described resin relief and form with the coating of coating liquid and keep coating liquid, afterwards the transfer printing of above-mentioned coating liquid is being printed on the body.Then, after coating liquid transfer printing, by making its drying, remove and desolvate and burn till, can form size and printing on the body with the corresponding oriented film in protuberance surface being printed.
And, as transfer printing the body that is printed of above-mentioned coating liquid limit especially in addition, can list material known in the past, for example glass plate, metal forming, metallic plate, plastic plate, plastic sheet, braid, nonwoven, paper etc.Wherein, from being difficult for absorbing the viewpoint of the coating liquid that is transferred, preferably adopt glass plate, metal forming, metallic plate.
Below, with comparative example embodiment is illustrated.
