Anyone knows what is "Latitol U"?

I found along some old books from my grandfather a lot of marks, etc, about a developing formula - the PAC´s "New Winchester". I would like to test this developer, because the blacks he used to get are very very difficult to obtain (I ever tought that the papers he used were the responsible, but maybe...)

 

The problem is that the formula uses two ingredients that I don't know. "Wettol" and "Latitol U". Wettol is a wetting agent, and I can try with any other. But how about Latitol? It would be like benzotriazole (Kodak Anti-fog 1), if I understood well. But then, how much of it?

 

Of course these are names, products, etc, from the 40s and 50s; but I really would like to try this.

Hi

 

Either Benz or potassium bromide need to be done with test strips as the effects depend on the Dev and paper, with chloro bromide papers and the correct developer then the potassium bromide can produce deep reds, but need more exposure but it is some time since I did that.

 

The only other thing I recall is the MQ devs liked the potassim bromide but Phenodine devs needed the Benz.

 

Sorry

Thanks, Noel!

 

This wekend I had the luck to talk with an old man (83 years old!) who remembers that Latitol would be like Kodak Anti-fog. So probably it is benzotriazole. Funny, because the developer has a lot of potassium bromide, too!
