Reaktionsschritte

The dispersion used in preparing the samples used in COMPARATIVE EXAMPLES 11 to 13 and INVENTION EXAMPLES 3 to 10 was obtained by first preparing a predispersion of 56.5 g of the dried silver behenate powder in a solution of 8.36 g of PVB in 72.6 g of 2-butanone by stirring for 2 minutes in a Dissolver™. This predispersion was then ground for 4 minutes in a pearl mill and just before the end of the 4 minutes a solution of 8.36 g of PVB in 72.6 g of 2-butanone was added. Finally a solution of 27.85 g of PVB in 242.3 g of 2-butanone was added to produce the type II organic silver salt dispersion of silver behenate in 2-butanone containing 11.18% by weight of silver behenate and 8.82% by weight of poly(vinyl butyral)(BL5-HPZ) used preparing the samples used in COMPARATIVE EXAMPLES 11 to 13 and INVENTION EXAMPLES 3 to 10.
