Definitions
- the present invention relates to a negative photosensitive white composition for a touch panel, a touch panel, and a method for manufacturing the touch panel.
- a projected capacitive touch panel has an ITO (Indium Tin Oxide) film pattern formed in a screen region, and a metal wiring portion such as molybdenum is further formed in the periphery thereof. And in order to hide such a metal wiring part, the light shielding pattern of black or white is often formed inside the cover glass of the projected capacitive touch panel.
- ITO Indium Tin Oxide
- Touch panel systems include an out-cell type in which a touch panel layer is formed between a cover glass and a liquid crystal panel, an on-cell type in which a touch panel layer is formed on the liquid crystal panel, and an in-cell type in which a touch panel layer is formed inside the liquid crystal panel. It is roughly divided into cell type and OGS (One Glass Solution) type that directly forms a touch panel layer on the cover glass, but it can be made thinner and lighter than the conventional out-cell type. The development of touch panels is becoming popular.
- OGS type touch panels are also required to form a light shielding pattern by lithography (Patent Document 1).
- Patent Document 2 a black light shielding pattern using a photosensitive black light shielding material
- a photosensitive white composition for a touch panel has not been developed in spite of the demand for a light-shielding pattern that is not black but white. This is because the white pigment contained in the photosensitive white composition has a lower light-shielding property than the black pigment, so that thick film processing is required and it is considered unsuitable for a normal touch panel process. Under these circumstances, it is possible to form a white light-shielding pattern with a high film thickness, high resolution, high reflectivity and light-shielding property by lithography, and in touch panel manufacturing processes such as heat treatment, chemical treatment and wiring processing. There is a need for photosensitive white compositions for touch panels that are less prone to problems such as yellowing, peeling or disconnection.
- the present inventors have developed a touch panel containing (A) a white pigment, (B) an alkali-soluble resin, (C) a polyfunctional monomer, and (D) a photopolymerization initiator. It has been found that the negative photosensitive white composition is extremely useful for forming a white light-shielding pattern for a touch panel.
- a light-shielding pattern having a higher resolution than that of the conventional printing method can be formed on glass even when a thick film of 10 ⁇ m or more is formed. Further, it is possible to form a touch panel white light-shielding pattern with high intensity of reflected light and less discoloration. Furthermore, it is possible to obtain a white light-shielding cured film pattern that is excellent in adhesive strength, does not peel off after chemical treatment in a subsequent process, and is less colored by heat treatment.
