I never knew you use ammonia dichromate to make screen resist...

ammoniUM dichromate can be found at unitednuclear.com - not sure if its what you're looking for - orange powder, highly toxic...
I don't know about ammonia dichromate, but I found potassium dichromate at a store in Montreal that sells pigment and chemicals for woodworking and ceramics. www.kamapigments.com (sorry I know it's not LA, but you can order it online) It's also available on Ebay
