Embodiment 1

[0078] A colloidal dispersion of silver particles was prepared by the above-mentioned Carey-Lea method.

[0079] Specifically, to 9% silver nitrate aqueous solution 33g, after adding the mixed solution of 23% iron (II) sulfate aqueous solution 39g and 37.5% sodium citrate aqueous solution 48g, after filtering and washing the precipitate, add pure water to prepare silver Colloidal dispersion of microparticles (Ag: 0.15%).

[0080] In this silver particle colloidal dispersion liquid 60g, under stirring, add hydrazine hydrate (N 2 h 4 ·H 2 O) 1% aqueous solution 8.0g, potassium aurate [KAu(OH) 4 ]Aqueous solution (Au: 0.75%) 480g and 1% polymer dispersant aqueous solution 0.2g mixed solution, the colloidal dispersion liquid of the silver particle that is coated with precious metal is prepared.

[0081] The colloidal dispersion of silver particles coated with precious metals was desalted with an ion exchange resin (manufactured by Mitsubishi Chemical Corporation, trade name Di...

Embodiment 2

[0096] In addition to the coating solution for forming a transparent coating in Example 1, the inorganic binder (SiO 2 ) 100 parts (weight), the addition of n-decyltrimethoxysilane is 1.0 parts (weight), and the same operation as in Example 1 is made to obtain the bonding of silver particles and silicon oxide coated with noble metals of conductive particles. The transparent conductive layer composed of the agent matrix and the transparent coating layer composed of the silicate film mainly composed of silicon oxide containing long-chain alkyl groups constitute the glass plate to which the transparent two-layer film is attached, that is, the transparent conductive layer of embodiment 2. base material.

[0097] The above film properties of the transparent two-layer film formed on the glass substrate are shown in Table 1 below.

Embodiment 3

[0099] In addition to the coating solution for forming a transparent coating in Example 1, the inorganic binder (SiO 2 ) 100 parts (weight), add n-decyltrimethoxysilane to reach 5.0 parts (weight), and operate in the same way as in Example 1 to obtain a bonded silver particle coated with precious metal and silicon oxide as conductive particles. A transparent conductive layer composed of an agent matrix and a transparent coating layer composed of a silicate film containing long-chain alkyl silicon oxide as a main component constitute a glass substrate to which a transparent two-layer film is attached, that is, the transparent film of Example 3 is obtained. Conductive substrate.

[0100] The above film properties of the transparent two-layer film formed on the glass substrate are shown in Table 1 below.
