Abstract

PURPOSE:To obtain a narrow-width, compact peeling development device and to improve its operation efficiency by installing a peeling bar so that it is adjusted into a slanting state in the conveyance direction of a substrate. CONSTITUTION:The peeling bar 6 is provided above a conveyer 5 which conveys the substrate 4 for image formation formed by sticking the photopolymerizing composite material layer side of an image forming material 3 having a layer of a photopolymerizing composite material on a transparent base 1; the peeling bar is adjustable freely within a range of 0-45 deg. to a perpendicular to the conveyance direction of the substrate and comes into linear contact with e image forming material. The tilt angle of the peeling bar 6 is adjusted pivotally by supporting one end of the bar rotatably and rotating and stopping the other end at a necessary angle. The substrate 4 is exposed to an image from above its stuck transparent base 1 and the substrate 4 is placed on the conveyer 5 so that the center line of the substrate 4 coincides with the conveyance direction of the substrate; and the transparent base 1 and an unexposed part of the photopolymerizing composite material which is still adhered to said base are peeled slantingly from the substrate 4 by the slanting bar 6.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a peel developing device, and particularly to a developing device for peel developing type image forming materials used for manufacturing printed circuits, etc. .

<Prior art> For manufacturing printed circuits, etc., the surface of an image forming substrate is coated with
The photopolymerizable composition layer side of an image forming material consisting of a transparent support and a photopolymerizable composition layer deposited on the support is pasted, and the photopolymerizable composition layer is applied in the form of an image. an image forming means for exposing to light to form a cured area, further heating the image forming material as necessary, and then peeling the support from the substrate to form an image-shaped resist on the substrate; In order to obtain sharp and well-finished images, a method is disclosed in JP-A-58-53882 and JP-A-Sho 58-53882, in which a transparent support to which an unexposed photopolymerizable composition is attached is peeled diagonally from a substrate. 59-58891, JP 59-58892, JP 59-143151, JP 59-181340
No. 59-181344, and others.

<Problems to be Solved by the Invention> However, in order to peel the transparent support obliquely from the substrate, it is necessary to position the substrate obliquely with respect to the transport direction as shown in FIG. The width of the peeling and developing device itself has become wider and the equipment has become enormous, and in the continuous pattern forming process of long substrates, such as flexible substrates, it is necessary to cover the unexposed areas of the transparent support in one continuous diagonal. There were drawbacks such as the inability to peel off 1'-8.

Figure 6 illustrates the above-mentioned peeling method.In contrast to the peeling bar b which is parallel to the perpendicular line of the conveying direction of the substrate a shown by the arrow, in order to perform diagonal peeling, the substrate a is placed in the conveying direction. On the other hand, it needs to be oblique, which causes the above-mentioned problems.

Means for Solving the Problems> The present invention has a peeling bar installed obliquely and adjustable with respect to the substrate transport direction, thereby making the peeling and developing device narrower and more compact. It is an object of the present invention to provide a suitable winding device for a support that is fed and conveyed straight to the direction and peeled off obliquely.

<Embodiments> Hereinafter, each embodiment of the present invention will be described based on FIGS. 1 to 5 of the accompanying drawings.

The first example shown in FIGS. 1 and 2 will be described below.

The substrate 4 is placed on top of the conveyor 5 that conveys the image forming substrate 4 on which the photopolymerizable composition layer side of the image forming material 3 in which the photopolymerizable composition layer is formed on the transparent support 1 is adhered. A peeling bar 6 is provided so as to be in line contact with the image forming material 3 so as to be adjustable within a range of 0° to 45° with respect to a perpendicular line perpendicular to the conveyance direction. The inclination angle of the peeling bar 6 can be adjusted by any configuration in which one end of the bar is rotatably fixed and the other end can be stopped at a desired angle, or by a support stand that supports both ends of the bar. Any configuration such as rotation can be adopted.

After imagewise exposure is performed on the transparent support 1 attached to the substrate 4, the substrate 4 is placed on the conveyor A75 so that the center line of the substrate 4 and the direction of conveyance of the substrate coincide, and the inclined bar 6 is used to expose the substrate 4 to light. The transparent support 1 and the unexposed portion of the photopolymerizable composition that remains adhered to the support are peeled off from the substrate 4 in an inclined manner.

Since the direction of the image pattern formed on the substrate 4 is not constant, the inclination angle of the peeling bar 6 is determined depending on the direction of the pattern.
Make sure that the peeling lines caused by the bar do not coincide, and adjust so that peeling can be performed at an optimal inclination angle.

Next, as a second example of the present invention, what is shown in FIGS. 3 and 4 is a transparent support that is peeled off by a peeling line that is inclined with respect to the conveying direction, as shown in FIGS. 1 and 2 above. The body 1 is provided with a take-up roll 7 which is supported above the peel-off bar 6 in parallel with the peel-off bar and whose angle with the surface of the substrate 4 can be adjusted within the range of 0° to 45°. The inclination angle β with respect to the substrate surface is made equal to the inclination angle α of the peeling bar 6, and the film is wound up.

In this way, the obliquely peeled transparent support 1, even if it is continuous and long, can be wound onto the winding roll 7 in a properly polymerized state.

In the figure, reference numeral 11 indicates a winding roll for the substrate 4.

FIG. 5 shows another example of the take-up roll, which is adjustable and supported so as to be parallel to the peeling bar 6, which is adjustable in the range of 0° to 45° with respect to the conveying direction of the substrate 4. However, the substrate 4 is wound onto a take-up roll 9 via an intermediate roll 8 or an intermediate bar parallel to the substrate 4.

In this case, by adjusting and using the intermediate roll 8 so that the inclination angle is the same as that of the peeling bar 6, the intermediate roll 8 can be wound onto the take-up roll 9 perpendicular to the substrate transport direction.

The unexposed portion of the photopolymerizable composition attached to the peeled transparent support 1 is attached to the intermediate roll 8 or the intermediate bar described above, and due to its adhesiveness, the transparent support 1 is smooth. Since the migration is hindered, measures can be taken to prevent the unexposed photopolymerizable composition from adhering, such as by holding a large number of rotatable balls 10 or rings on the roll surface, or by special surface treatment. .

<Effects> As described above, according to the present invention, a compact peeling developing device with a narrower width than the conventional peeling developing device can be obtained, and it is particularly suitable for processing long substrates or continuous long substrates, which could not be done with conventional devices. Since the diagonal peeling of the short substrates can be continuously performed and the support body, which becomes sloped due to the diagonal peeling, can be continuously wound up, it has the effect of improving work efficiency.
