PRE-STRESSED SUBSTRATE FOR PHOTOGRAPHIC PAPER |
摘要 |
<p>A pre-stressed substrate for a photographic paper includes a base paper having a front surface and a back surface; a top pre-stress coat on the front surface, the top pre-stress coat including a first pre-stress mixture containing at least a first pigment, a first binding material including a first water soluble binder and a first water-dispersible binder; and a back pre-stress coat on the back surface, the back pre-stress coating including a second pre-stress mixture containing at least a second pigment, a second binding material including a second water soluble binder. The weight % of the first water soluble binder in the first binding material is less than the weight % of the second water soluble binder in the second binding material. The pre-stressed substrate has a predetermined degree of curvature toward the back surface and is capable of countering curling forces that occur when the pre-stressed substrate is used.</p> |
