Yes, RC does still refer to resin coated. The Premium Luster, P. Semi Gloss, P. Glossy are 
inkjet papers that are poly resin coated, though certainly not identical to gelatin silver rc 
material. They have an ink receptor coating, not a polymer-silver coating, on the plastic 
base, but they look and feel pretty much the same, hence the term rc. The correct 
technical term for this type of inkjet paper is "microporous"  inkjet media. That refers to 
the micro sized pores that the coating contains that allow the inks to penetrate slightly 
below the surface in building up the image. There is another type of rc inkjet media called 
swellable polymer, that was designed to provide more protection to dye inksets such as 
used in the Epson 1280, etc. to protect them from gas fading.
