Abstract
Abstract A recording medium for ink-jet recording has an ink-receiving layer comprising spherical basic magnesium carbonate, amorphous magnesium carbonate or a mixture of aluminum oxide and basic magnesium carbonate. The recording medium promises a good storage stability of recorded images, i.e. less deterioration due to indoor color changes, together with a high image density.
