Beschreibung
Zusammenfassung:	The present invention relates to a UV absorbent including a microalgae extract and a coating composition for blocking or absorbing UV rays including the same. In general, a transparent coating film is yellowed when exposed to ultraviolet rays for a long time. To this end, the present invention prevents yellowing even when the transparent coating film is exposed to UV light for a long time by increasing resistance to UV light by including the microalgae extract. 본 발명은 미세조류 추출물을 포함하는 자외선 흡수제 및 이를 포함하는 자외선 차단 또는 흡수용 도료 조성물에 관한 것으로 일반적으로 투명색의 도막은 장시간 동안 자외선에 노출되면 황변이 발생하는데 본 발명에서는 이를 해결하기 위하여 미세조류 추출물을 포함하여 자외선에 대한 저항성을 높임으로써 투명색의 도막이 장시간 동안 자외선에 노출되더라도 황변 발생을 방지한다.
