Abstract: 도로 표시재는 불균일한 노면에 정합성을 갖는 유연한 베이스 시트(11)를 구비한다. 2방향으로 불연속되고 내구성 및 내마모성이 있는 중합체 상부층(18)이 상기 베이스 시트의 일면에 부착된다. 중합체 상부층은 웨브의 종횡 양방향으로 모두 불연속된다. 이러한 2방향 불연속성은 회전식 스크린 인쇄 공정과 같은 연속 공정으로 획득할 수 있다. 회전식 스크린 인쇄 공정은 코팅될 조성물이 도포 온도에서 무기한의 저장 기간을 갖는다면 더욱 효과적이다. 이러한 무기한의 저장 기간은 블록화된 이소시아네이트 가교제를 사용함으로써 가능하다. 중합체 상부층의 2방향으로의 불연속성은 불균일한 노면에 대해 도로 표지의 향상된 초기 정합성을 제공한다. 중합체 상부층의 불연속성은 또한 연속된 상부층에 조성되어 접착제 손상을 초래하는 경향을 띠는 탄성 인장 응력을 감소시킨다. 역반사성 소구체 및/또는 미끄럼 저항성 입자인 다수의 입자들이 불연속의 상부층에 매입되고, 이 상부층으로 부터 돌출된다.
