This invention aims to provide a transparent conductive laminate excellent in sliding durability, edge-writing durability, finger writing durability and light resistance and suitable as a movable electrode substrate for a touch panel. Further, it aims to provide a touch panel using the above transparent conductive laminate. This invention is a transparent conductive laminate that is a laminate formed by laminating a polymer film, a cured resin layer-1 and a transparent conductive layer in this order, the cured resin layer-1 having concavoconvex shapes formed by phase separation of two components and containing no fine particles that impart concavoconvex shapes, and the cured resin layer-1 having an arithmetic average roughness (Ra), measured according to JIS B0601-1994, of 0.05 &#x3bc;m or more but less than 0.5 &#x3bc;m and a ten-point average roughness (Rz), measured according to JIS B0601-1982, of 0.5 &#x3bc;m or more but less than 2.0 &#x3bc;m, and a touch panel using the transparent conductive laminate.

Transparent conductive laminate and touch panel

The present invention imparts elasticity, reproducibility of dots, film toughness and wear resistance to printing plates obtained therefrom, in addition to good water developability and mechanical properties, by providing a photosensitive resin composition comprising:

Photosensitive resin composition

Water-developable photosensitive composition for producing relief plates

Disclosed is a photosensitive resin composition for flexographic printing which has high water developability and good mechanical strength. The resin composition comprises (A) a partially crosslinked copolymer prepared by a radical emulsion polymerization of a specific monomer mixture (B) a linear polymer having a molecular weight of at least 5,000, which has at least 30 mol % of a conjugated diene unit, (C) a basic nitrogen atom-containing compound, (D) a photopolymerizable ethylenically unsaturated monomer, and (E) a photopolymerization inhitiator. The present invention also provides a resin plate for flexographic printing obtained from the above mentioned resin composition and a process for preparing it. The present invention further provides a printing plate obtained from the resin plate and a process for preparing it.

Disclosed is a photosensitive flexographic resin plate having excellent wear resistance and giving relief image faithful to a negative film. The photosensitive flexographic printing plate is composed of a base plate and a photosensitive resin layer thereon wherein said photosensitive resin layer is formed from a resin composition comprising a resin having rubber elasticity, an unsaturated monomer, a photopolymerization initiator and resin particles having an average particle size of about 0.01 to 6 micron, and when said photosensitive resin layer is cured, the cured layer has a JIS A hardness of 30.degree. to 80.degree. and an impact resilience of at least 20%.

Photosensitive flexographic resin plate

There is hereby provided a photosensitive resin composition suitable for a relief printing plate having an excellent resistance to a water based ink, whereby water or a water like solvent can be employed as a developing solution, which comprises;
