I don't know if the brand is available outside New Zealand, but it is 
"fresh*paper" brand OCCASIONS Photo & Presentation paper. 180 gsm glossy 
paper, glossy on one side ffairly rough on the other, made in China. I 
haven't had access to a mass spectrometer for several years so I don't 
know what the coating is, I just assumed it was Kaolin. There is a 
website listed http://www.freshprintcompany.com but I can't connect to it.
