PROBLEM TO BE SOLVED: To provide a vinyl chloride-based copolymer resin which does not leave insolubles, when dissolved in an organic solvent, has good particle diameters, a good particle size distribution, and excellent thermal stability, and is extremely practically advantageous as a resin used for inks and coatings due to the characteristics. SOLUTION: This vinyl chloride-based copolymer resin comprises 75 to 91 mol.% of vinyl chloride units, 9 to 25 wt.% of fatty acid vinyl ester units, and 0 to 10 wt.% of other monomer units, and has an average degree of polymerization of 300 to 800 and excellent solubility in organic solvents.
