Matrix (A) also blends into and is integral with a transparent outer wear layer (B) which seals off the outer, visible side of the paper which is subject to use. Layer (B) is formed with components (a1)-(a3) as above, but also contains dispersed particles of (a4) abrasion-resistant hard material or alpha -aluminium oxide or alpha -corundum.
