Embodiment

[0107] Hereinafter, the present invention will be described in more detail using examples and comparative examples, but the present invention is not limited to the following examples.

[0108]

[0109] "Surface Tension"

[0110] About the photosensitive black resin composition obtained by each Example and the comparative example, the surface tension was measured at 25 degreeC using the automatic surface tensiometer K11 (made by KRUSS company) using the platinum plate.

[0111] "Contact angle"

[0112] On alkali-free glass (#1737, manufactured by Corning Co., Ltd.) washed with an alkaline detergent (HEM026-058 (manufactured by Wakenyaku Co., Ltd.)), dropwise added For the photosensitive black resin composition, the contact angle was measured using a portable contact angle meter PCA-1 (manufactured by Kyowa Interface Science Co., Ltd.).

[0113] "viscosity"

[0114] About the photosensitive black resin composition obtained by each Example and the comparative example, the vi...

Synthetic example 1

[0127] By the method described in Example 1 of Japanese Patent No. 3120476, methyl methacrylate / methacrylic acid / styrene copolymer (weight composition ratio 30 / 40 / 30) was synthesized, and glycidyl methacrylate was added 40 parts by weight of the ester were reprecipitated with purified water, filtered, and dried to obtain an acrylic polymer (P-1) powder having an average molecular weight (Mw) of 20,000 and an acid value of 110 (mgKOH / g).

Embodiment 1

[0130] 175 g of high-resistance carbon black TPK1227R (manufactured by Cabot Co., Ltd.), 171 g of a 35% by weight solution of propylene glycol monoethyl ether acetate of an acrylic polymer (P-1), and Disperbic LPN-21116 as a polymer dispersant (Propylene Glycol Monoethyl Ether Acetate 40% by weight solution, manufactured by Bic Chemical Co., Ltd.) and 616 g of Propylene Glycol Monoethyl Ether Acetate (PMA) were put into a tank, and stirred for 20 minutes with a homomixer (Priumix). , to obtain a predispersion. Then, the predispersion was supplied to Ultra Apex Mill (manufactured by Kotobuki Kogyo Co., Ltd.) filled with 75% of 0.05 mmφ zirconia beads (manufactured by Daiken Chemical Industry Co., Ltd., YTZ balls) for centrifugal separation, and Dispersion was carried out for 3 hours at a rotation speed of 8 m / s to obtain a black dispersion liquid 1 having a solid content concentration of 25% by weight and a coloring material / resin (weight ratio)=70 / 30.

Abstract

The object of the present invention is to provide a colored resin composition capable of suppressing sinking and unevenness and forming a colored film having a good appearance even when it is applied by spraying or inkjet. The present invention is a colored resin composition comprising at least: (A) a coloring material, (B) a binder resin, (C) an organic solvent, and two or more kinds of (D) surfactants, as the above-mentioned surfactants, Containing (D1) polyether-modified siloxane-based surfactant and (D2) silicon-modified acrylic-based surfactant, the total content of the above-mentioned surfactants (D1) and (D2) in the colored resin composition is 200ppm Above 1500ppm below.

Description

technical field [0001] The present invention relates to a colored resin composition containing at least a coloring material, a binder resin, an organic solvent, and two or more surfactants, and a colored film and a decorative substrate for a touch panel using the colored resin composition. Background technique [0002] Conventionally, a touch panel device is generally mounted on the front surface of a display panel such as a liquid crystal display device, and a cover glass having a light-shielding film formed by printing a black ink composition is bonded to the front surface of the touch panel. However, such an external touch panel structure has the problem of increased thickness and weight. [0003] Therefore, in recent years, as a display device having a touch sensor function, a cover glass-integrated touch panel has been proposed in which a conductive film and a sensor are directly formed on a cover glass, and a single glass acts as both a cover glass and a touch sensor. ...
