The present invention aims to provide a substrate having an ITO with a low ITO pattern visibility, which substrate is formed by a method utilizing a simple technique such as coating, printing or the like, and which method is less burdensome from the viewpoints of cost and process; and to provide a touch panel member using the substrate. The present invention provides a substrate including a region where thin layers are laminated on a transparent ground substrate, which thin layers are, in the order mentioned from the upper surface of the substrate: an ITO (Indium Tin Oxide) thin layer (I); an organic thin layer (II) having a film thickness of from 0.01 to 0.4 &#x3bc;m and a refractive index of from 1.58 to 1.85; and a transparent adhesive thin layer (III) having a refractive index of from 1.46 to 1.52.

Substrate and touch panel member using same

The present invention provides a negative-type photosensitive white composition for a touch panel, the composition including: (A) a white pigment; (B) an alkali-soluble resin; (C) a polyfunctional monomer; and (D) a photopolymerization initiator.

Negative-type photosensitive white composition for touch panel, touch panel and touch panel production method

The purpose of the present invention is to provide a negative-type photosensitive coloring composition ideal for forming a white, light-blocking pattern and which not only has excellent chemical resistance, but also has extremely excellent heat resistance and does not yellow or crack even when undergoing high-temperature processing. This negative-type photosensitive coloring composition contains (A) a white pigment, (B) a polysiloxane obtained by co-hydrolyzate condensation of an alkoxysilane compound containing a compound of a specific structure, (C) polyfunctional acrylic monomers, (D) a photoradical polymerization initiator and (E) an organic solvent.

Negative-type photosensitive coloring composition, cured film, light-shielding pattern for touch panel, and touch panel manufacturing method

A siloxane resin composition is provided which is superior in pattern processability and yields a cured film with high hardness and excellent abrasion resistance by means of UV curing and thermal curing. The siloxane resin composition includes (A) polysiloxane having a carboxyl group and a radical polymerizable group, (B) a photo-radical polymerization initiator and (C) a compound having a radical polymerizable group and not having a Si&#x2014;O&#x2014;Si bond.
