Konica Photo IJ Paper QP is an example of how microporous glossy paper allows today's ink jet printing to challenge the image quality of silver halide prints. QP paper incorporates ICOS particles in tandem with a polyvinyl alcohol binder and boric acid hardener, resulting in high ink-absorption capacity for exceptionally quick drying and fine resolution. These technologies further ensure the fixing of ink dyes, maintain the high gloss of the paper, and provide image-receiving layers that are physically strong and highly water resistant.
