DISPERSION, COATING SLIP AND ABSORPTIVE MEDIUM

摘要

Stable, aqueous dispersion containing powders A and B, - wherein powder A is an amorphous silicon dioxide powder having an average particle diameter of 0.05 to 0.7 µm and a BET surface area of 5 to 50 m<2>/g, and - wherein powder B is a metal oxide or non-metal oxide powder consisting of aggregates of intergrown primary particles and displays a primary particle size of 5 to 50 nm and a BET surface area of 50 to 400 m<2>/g. Coating slip to form an ink-absorptive coating using the dispersion and at least one hydrophilic binder. Absorptive medium using the coating slip and a support.
