[0028] The solution II can be prepared by a conventional method for preparing solution II, for example, glucose, SnCl 2 , HCl, SnCl 4 It can be dissolved in water. Preferably, the glucose is first dissolved in a part of the water, and then the SnCl 2 Dissolve in 36% HCl, finally mix the two and add the remaining part of water to prepare solution II.
[0029] The amount of solution II can be a conventional amount, as long as the solution II covers the entire surface of the holographic master. The conditions for sensitization and the way of spraying solution II are not particularly limited. For example, the sensitization time is preferably 1-10 minutes, more preferably 3-5 minutes; the sensitization temperature is preferably 5-50°C, more preferably 15°C-40°C. Preferably, the solution II is sprayed onto the surface of the holographic master by spraying the solution II with a single nozzle spray gun. After spraying solution II, the surface of the holographic master can be cle...

[0037] Dissolve 60 grams of glucose in 300 ml of distilled water, boil for 5 minutes, add 200 ml of distilled water with stirring after cooling, then add 4 grams of lead acetate with stirring, and add 50 grams of ethanol, stir well, add distilled water to the total volume of the solution In 1000 ml, a solution (solution III) for transplanting a silver surface of a holographic image according to the present invention was prepared.
[0038] Dissolve 40 grams of silver nitrate in 300 ml of distilled water. After it is completely dissolved, add 5 grams of sodium hydroxide into the silver nitrate solution to form a precipitate, then slowly add 30 grams of NH to the silver nitrate solution while stirring. 4 OH, the resulting precipitate was just dissolved, and after adding 0.5 gram of iodine under stirring, distilled water was added until the total volume of the solution was 1000 milliliters to obtain solution IV of the present invention. (the stable time of solution IV is shown in ...
