Zusammenfassung:	The present invention relates to a method for a nano-size non-aqueous dispersion resin and to a paint composition using the same. The non-aqueous dispersion resin according to the present invention is a resin synthesized by making caprolactone-modified acrylic monomer, an acrylic multifunctional monomer and an acrylic monofunctional monomer react in the presence of an initiator and a solvent via solution polymerization method, wherein the particle size of the resin is 100 nm or smaller. The non-aqueous dispersion resin according to the present invention reduces the VOCs of paint as the non-aqueous dispersion resin has viscosity lowered while exhibiting excellent miscibility with paint resin when added to the paint. In addition, the non-aqueous dispersion resin can improve the scratch resistance, acid resistance and chipping resistance of a membrane by being involved in curing reaction. 본 발명은 나노사이즈의 비수분산 수지의 제조방법 및 이를 이용한 도료조성물에 관한 것이다.본 발명에 따른 비수분산 수지는, 카프로락톤 변성 아크릴계 모노머, 에틸렌성 불포화기를 1개 갖는 아크릴계 모노머 및 에틸렌성 불포화기를 2개 이상 갖는 아크릴계 모노머를 개시제 및 용매 존재하에서 용액중합법을 통해서 반응시켜 합성된 수지로서, 상기 카프로락톤 변성 아크릴계 모노머는, 전체 모노머 함량에 대하여 30~99㏖%이고, 상기 에틸렌성 불포화기를 2개 이상 갖는 아크릴계 모노머는, 전체 모노머 함량에 대하여 1~20㏖%이며, 상기 수지 입자의 크기는 100㎚ 이하인 것을 특징으로 한다.본 발명에 따른 비수분산 수지는 도표에 첨가될 경우, 도료 수지와 양호한 상용성을 나타내면서 점도를 낮추어, 도료의 VOC를 저감시킬 뿐 아니라, 경화반응에 참여하여 도막의 내스크래치성, 내산성, 내치핑성을 개선할 수 있다.
