Problems solved by technology

However, when electrodes and wirings made of metal are formed on the display surface, there is a problem that the user of the touch panel can easily recognize the metal electrodes and metal wirings visually. Even if it is so fine that the human eye cannot visually recognize it, the following problems still arise: Reflection of external light due to the high reflectivity of the metal

[0296] (Preparation method of positive type composition)

[0297] The positive type composition can be prepared by blending the above-mentioned components at predetermined ratios, followed by mixing and stirring by a normal method. In addition, if necessary, further filtration may be performed using a mesh, a membrane filter, or the like.

[0298] Next, the substrate 10 having the coating film 12 formed as described above is subjected to an exposure step.

[0299]

[0300] image 3 (c)~ image 3 In (f), the case where a positive photosensitive composition was used as a photosensitive resin composition was illustrated. When using a negative photosensitive resin composition as the photosensitive resin composition, a photomask 15 capable of blocking exposure light 16 irradiated to a position other than the position of the metal wiring 18 can be used.

[0301] In the case of using a positive photosensitive composition as the photosensitive resin composition, in the exposure ...

Embodiment 1

[0361] 100 parts by mass of Novolac resin, 13 parts by mass of a sensitizer, 22.6 parts by mass of a quinonediazide group-containing compound, and 27 mass % of a pigment relative to the mass of the total solid content were uniformly dissolved and dispersed in propylene glycol monomethyl In the base ether acetate, the solid content concentration was adjusted to 20% by mass to obtain a positive tone composition.

[0362] It should be noted that in the positive type composition, 1% by mass of 2-hydroxyethylpyridine and 0.4% by mass of silicon-based surfactant ( BYK-310, manufactured by BYK Chemie).

[0363] As the Novolac resin, a cresol-type Novolac resin having a weight average molecular weight of 4700 and a degree of dispersion of 4.5 was used.

[0364] As the sensitizer, a phenolic resin (trade name: TrisP-PA-MF, manufactured by Honshu Chemical Industry Co., Ltd.) was used.

[0365] As a compound containing a quinonediazide group, a product obtained by esterifying 2,3,4,4'-...

Embodiment 2

[0380] The Novolac resin was changed to a cresol-type Novolac resin with a weight average molecular weight of 4700 and a degree of dispersion of 10.0, except that a positive-type composition was prepared in the same manner as in Example 1, and it was operated in the same manner as in Example 1 to obtain A laminated body consisting of metal wiring and a colored resin layer is formed on a substrate.

[0381] The optical density of the formed covering resin layer was 0.60 / μm.

[0382] In addition, when the shape of the formed colored resin layer was observed with a microscope, the film thickness of the colored resin layer was substantially uniform, and when the surface of the substrate on which the metal wiring was formed was observed from a direction perpendicular to the surface, the upper part of the pixel was not covered. The colored resin layer was covered, and metal wiring was not exposed.

[0383] For the formed laminate formed by the metal wiring and the colored resin lay...

Abstract

The present invention relates to a laminate and a method for producing the laminate. An object of the present invention is to provide a laminate formed of metal wiring and a colored resin layer covering the metal wiring. When a substrate having the laminate is applied to an image display device, the metal wiring is not easily recognized by the user, and the Since the coloring resin layer has little influence on light transmission and color mixing, an image display device capable of displaying high-quality images can be produced; and a method for producing a laminate that can suitably produce the laminate is provided. . The solution of the present invention is: when the laminated body formed by the metal wiring and the colored resin layer covering the metal wiring is produced by baking the colored resin layer covering the metal wiring, by adjusting the baking conditions, the A laminate of a metal wiring and a colored resin layer covering the metal wiring in an ideal state is used.

Description

technical field [0001] The present invention relates to a laminated body in which light-shielding metal wiring and a colored resin layer containing a coloring agent are stacked in contact with each other and provided on a light-emitting unit; and a method for manufacturing the laminated body. Background technique [0002] With the rapid spread of smartphones and tablet-type information communication terminals, the touch panel market is growing rapidly. [0003] In such a touch panel, electrodes and wiring made of metal may be formed on the display surface. For example, as such an electrode, a metal mesh electrode using Cu or Ag is mentioned. However, when electrodes and wirings made of metal are formed on the display surface, there is a problem that the user of the touch panel can easily recognize the metal electrodes and metal wirings visually. Even if it is so fine that the human eye cannot visually recognize it, there still arises the following problem: reflection of ex...
