Research is pure research not directed to any product.
Development is work on an existing product to tweak it or to solve problems in the field from customers.
R&D is directed to a new product and includes all phases up to introduction. It takes elements from pure research and includes them in the new product.
For example, if one is training a new coating engineer (which Kodak is doing BTW) it is not R&D nor is it R and D. It is pure Manufacturing Technology, another subject that has not been discussed except in Simon's post. So, Kodak can stop R, D and R&D, but still be training Manufacturing Technologists and Engineers so that they keep on coating film. They may be training Development Engineers to keep making emulsions and etc..... This is a simple answer to a very complex situation.
