Embodiment 1
[0177] (Example 1) Coating method
[0178]
[0179] 23.1 g silver(I) acetate, 65.1 g tin(II) acetate, 54 g gluconic acid, 45 g sodium pyrophosphate, 2 g polyethylene glycol (molecular weight 3,000) and 5 g E735 (produced by ISP; vinylpyrrolidone / vinyl acetate ester copolymer) was dissolved in 1000 ml of purified water to obtain solution 1.
[0180] Separately, 36.1 g of hydroxyacetone was dissolved in 500 ml of pure water, whereby solution 2 was obtained.
[0181] Solution 1 obtained above was vigorously stirred at a constant temperature of 25° C., solution 2 was added thereto within 2 minutes, and the mixture was slowly stirred for 6 hours. The mixed solution turned black, whereby silver-tin alloy-containing metal particles (also called silver-tin alloy-containing particles) were obtained. The solution was then centrifuged to precipitate the silver-tin alloy containing particles. Centrifugation was performed at a rotation speed of 2,000 r.p.m for 30 minutes by distributi...
Embodiment 2 to 6， comparative example 1 to 3 and comparative example 5
[0208] (Examples 2 to 6, Comparative Examples 1 to 3 and Comparative Example 5): Coating method
[0209] A dispersion solution was prepared in the same manner as in Example 1 and a substrate with a light-blocking film was prepared, except that the solution used in Example 1 to prepare a dispersion solution (dispersion solution A1) of particles containing a silver-tin alloy was prepared. The amounts of 23.1 g of silver (I) acetate and 65.1 g of tin (II) acetate were changed to the amounts [g] shown in Table 1. By the same X-ray scattering as in Example 1, it was confirmed that the particles in Examples 2 to 5 were composite materials composed of AgSn alloy and Sn metal or Ag metal, and it was confirmed that
[0210] The particles in Example 6 are AgSn alloy.

Embodiment 7
[0213] (Embodiment 7): transfer method
[0214] Dispersion solution A7 was prepared in the same manner as in Example 1, except that 23.1 g of silver acetate (I) and The amount of 65.1 g of tin(II) acetate was changed to the amount [g] shown in Table 1, and a substrate with a light-blocking film was prepared in the same method as in Example 1, except that by using The transfer method of the photosensitive transfer material instead of the coating method using the coating solution containing the dispersion solution A7 forms a black matrix. By the same X-ray scattering as in Example 1, it was confirmed that the silver-tin alloy-containing particles were a composite material composed of AgSn alloy and Ag metal.
[0215] The preparation of a photosensitive transfer material and the preparation of a substrate with a light-blocking film using the photosensitive transfer material will be described below.
