After coating, dimethylformamide was removed by washing with water, the film was solidified, and then dried to obtain a porous wet silver surface layer. Subsequently, caprolactone glycol and diphenylmethane-4,4'-
A solution consisting of 105L of polyurethane elastomer synthesized from diisocyanate and ethylene glycol, 60% of methyl ethyl ketone, 20% of dimethylformamide and 20% of tetrahydrofuran was applied at a solid content of 5 g/m', and then dried to form a clear layer. The solvent of the above composition solution used to form this clear layer was:
