A paint composition for silk printing, and a method for forming a coating by using the composition are provided to improve the hardness, processability, adhesion, solvent resistance and pollution resistance of a coat. A paint composition for silk printing comprises 20-60 wt% of a polyester resin; 5-20 wt% of a melamine compound; 1-5 wt% of a porous silica having a pore volume of 1.5-2.5 mL/g and an average diameter of 2-10 micrometers; and the balance of a solvent. Preferably the polyester resin has a number average molecular weight of 1,000-8,000, a hydroxyl number of 40-80 mg KOH/g and an acid number of 5-15 mg KOH/g; and the melamine compound comprises a methylated melamine formaldehyde resin. |
