Found paper.

[Mike Kennedy]

There were 10 boxes of 11x14 Kodak paper at my local thrift shop this morning.As to be expected, 4 of them had been opened and the paper leafed through.I did take home 2.One is marked Kodak KNP, the other is Kodak KRPM.
Looks interesting but what the heck is it?

These are PMT diffusion transfer papers. The negative is usually exposed in a graphic arts camera and run through a processor together with the positive paper. From the days of cut and paste artwork.
