More Information
Summary:Disclosed is a decorative sheet capable of improving elongation and scratch resistance more than existing polyethylene terephthalate glycol (PETG) sheets by forming a multilayered structure including a first layer containing an acrylic copolymer and a second layer containing PETG. The decorative sheet with excellent scratch resistance according to the present invention includes: a first layer containing an acrylic copolymer which includes a glycidyl group; and a second layer containing PETG. The thickness of the first layer is 20-80 m. 아크릴계 공중합체를 포함하는 제1층 및 PETG를 포함하는 제2층을 포함하는 다층 구조로 형성함으로써, 기존의 PETG 시트보다 연신율, 내스크래치 특성을 향상시킬 수 있는 데코 시트에 대하여 개시한다. 본 발명에 따른 내스트래치 특성이 우수한 데코 시트는 글리시딜기를 포함하는 아크릴계 공중합체를 포함하는 제1층; 및 폴리에틸렌테레프탈레이트글리콜(polyethylene terephthalate glycol:PETG)을 포함하는 제2층;을 포함하고, 상기 제1층의 두께는 20~80㎛인 것을 특징으로 한다.
