Problems solved by technology

[0006] Although the photosensitive resin composition is satisfactory in terms of sensitivity, it is insufficient in terms of water resistance and adhesion to the screen during development.
Especially when applied to metal screens such as circular screens mainly composed of nickel, there is a problem that the adhesion to the screen is not sufficient during development, resulting in detachment of thin lines and dots, and the desired pattern cannot be obtained.

preparation example Construction

[0078]

[0079] Preparation of the 1st photosensitive resin composition of this invention can be performed by arbitrary methods. In the present invention, it is preferably producible by adding each of the above-mentioned components directly or in a solution state to a suitable solvent and mixing the respective components. Water is most preferred as the solvent.

[0080] When manufacturing the printing plate for screen printing from the photosensitive resin composition of this invention, it is preferable to make the photosensitive resin composition into a solution form suitably. Therefore, in the case where the preparation of the photosensitive resin composition according to the present invention is carried out by adding each component directly or in the form of a solution to a solvent and mixing the components as described above, it is preferable to mix the prepared preparation liquid directly or as needed. After adding or removing a solvent (preferably water), it is used i...

Embodiment 1

[0119] Dissolve 15 g of polyvinyl alcohol with an average degree of polymerization of 2400 and a degree of saponification of 80% in 85 g of water, add 0.5 g of 3-methacryloxypropyltrimethoxysilane while stirring the solution, and then, in the emulsion A photosensitive resin composition was prepared by adding 10 g of a 5.5% aqueous solution of diazo resin (paraformaldehyde condensate of p-diazodiphenylamine).

Embodiment 2

[0121] Using 4,4'-diazide-stilbene-2,2'-disulfonic acid instead of the diazo resin in Example 1, a photosensitive resin combination was prepared in the same manner as in Example 1 things.

Abstract

[Problem] To provide, without using harmful substances, a photosensitive resin composition having a high resolution and sensitivity, and exhibiting excellent water, solvent and abrasion resistance, and adhesion to a screen mesh. [Solution] A photosensitive resin composition characterized by comprising the following components A, B, and C: component A being a polyvinyl alcohol and / or a partially saponified polyvinyl alcohol; component B being a water-soluble photoreactive cross-linking agent; and component C being a silane coupling agent. A stencil for screen printing using the aforementioned photosensitive resin composition.

Description

technical field [0001] The present invention relates to a photosensitive resin composition and a printing plate for screen printing using the photosensitive resin composition. Background technique [0002] For a long time, various compositions of photosensitive resin compositions have been continuously proposed. Especially for the photosensitive resin composition used in the manufacture of printing plates for screen printing, in addition to high resolution and high sensitivity, in order to adapt to pressure and friction in the environment of oil-based ink and water-based ink, etc., water resistance, water resistance, etc. Solvent resistance, abrasion resistance and adhesion to the screen are also important. [0003] Such a photosensitive resin composition is mainly composed of polyvinyl alcohol (PVA) and dichromate so far. This solution has excellent photosensitivity and excellent water resistance that is fully qualified for actual printing. However, with such a compositi...
