Problems solved by technology

[0005] However, especially in the case of white photosensitive resin, when the coating film is heated to harden or in the process of manufacturing a touch panel, it may be discolored and colored by heat, and there is a concern that the light reflectance may decrease.
In addition, if the light resistance is insufficient, it will be colored during use of the touch panel, or the light reflectance will be reduced

Abstract

The invention relates to a white photosensitive resin composition, a cured product using the same, and a touch panel including such cured product as a component. Concretely, the invention provides a white photosensitive resin composition, a cured product formed by heat curing a patterned white photosensitive resin composition through photoetching, and a touch panel including such cured product, wherein the white photosensitive resin composition includes (A) preset alkali-soluble resin, (B) a photopolymerizable monomer with at least one ethenoid unsaturated bond, (C) photoplymerization, and (D) a white shading material; in addition, the proportions of monomers becoming solid contents after light hardening in the solid contents are as follows: (A) is 1-55 mass%, 100 mass parts relative to (A), (B) is 10-100 mass parts, 100 mass parts relative to the sum of (A) and (B); (C) is 0.1-40 mass parts, and (D) is1-95 mass%.

Description

technical field [0001] The present invention relates to a white photosensitive resin composition capable of forming a desired pattern and having excellent light discoloration resistance. Specifically, a cured product thereof is used for the white photosensitive resin composition. The cured product can also be used as a decorative white material for a touch panel, and a touch panel comprising the cured product as a component. Background technique [0002] In recent years, due to the diversification of information equipment and the trend of small and lightweight mobile terminals, mobile phones, mobile information terminals, car navigation systems, and other flat-panel displays such as touch panels and liquid crystal display panels are integrally formed in the market. Touch-panel flat-panel displays integrated with input and display have become popular. There are various types of touch panels, such as resistive film type and electrostatic capacitive type, depending on their s...
