The formatton process of non-silver tmages conststing of Cu (II) chelates with 8-mercapto-5-methylthioguinoline has been studied. The unusual course of D ∇= f (DAg) curves (D∇ is a density of non-stiver imaimage obtained from an original silver image having DAg density) where D ∇values were decreased with DAg growth at some 8-mercapto-5-methyl-thioquinoline concentrations in the tolution and DAg ranges, has been observed.
