Abstract
The present invention provides: PA1 (1) a polysaccharide derivative having hydrophilic functional groups and nitrate groups per one repeating unit in the following range: EQU 0.2.ltoreq.X.ltoreq.1.5, 0.4.ltoreq.Y.ltoreq.2.2, X+Y<3; PA1 wherein X and Y represent the number of hydrophilic functional groups and nitrate groups, respectively; PA1 (2) the neutralized polysaccharide derivative; PA1 (3) the composition used as a binder containing the neutralized polysaccharide and water; and PA1 (4) the composition used as a vehicle containing the neutralized polysaccharide, a resin, an organic solvent and water. The vehicle composition has excellent properties such as drying characteristic, pigment dispersibility, compatibility with water soluble resins and thixotropic property, and it can form a clear continuous film having excellent heat resistance and blocking resistance.
