Abstract

The invention provides a hard coating with excellent etching resistance, a laminate for forming a transparent conductive film and capable of stably enabling a pattern shape of a transparent conductive layer to be invisible and providing the transparent conductive film with excellent adhesion resistance, and a transparent conductive film using the laminate. The laminate is made from the hard coating, a substrate film and an optical adjustment layer through laminating in sequence. The hard coating is formed from a composition containing components of (A) 100 parts by weight of an active energy ray cured resin and (B) 15-100 parts by weight of silicon dioxide micro-particles through photo-curing.

Description

technical field [0001] The present invention relates to a laminate for forming a transparent conductive layer and a transparent conductive film. [0002] In particular, it relates to a laminate for forming a transparent conductive layer which is excellent in etching resistance of a hard coat layer, can stably make the pattern shape of a transparent conductive layer invisible, and has excellent blocking resistance of the obtained transparent conductive film, and use of the layer Integrated transparent conductive film. Background technique [0003] Conventionally, a touch panel capable of inputting information by directly touching an image display unit is formed by disposing a light-transmissive input device on a display. [0004] As a representative form of such a touch panel, there is a resistive film type touch panel in which two transparent electrode substrates are arranged so that the respective transparent electrode layers face each other while providing a gap. touch p...
