Fifteen or more years ago, I picked up on sale a pack of 50 sheets of 13x19 RC glossy inkjet paper sold under the TDK label: as in the Japanese company who used to make magnetic tape and CDROM's. The explanation on the cover sheet seemed to be saying it had some sort of micro-porous ink-receiving layer. 264g/m²
For various reasons, I never opened it until last night. And I really liked the results!
Has anyone else ever used it?
