기재는상기 색변환필름의제조시지지체로서의기능을할수있다.기재의 종류로는특별히 한정되지 않으며,투명하고,상기지지체로서의 기능을할수 있는것이라면그재질이나두께에 한정되지 않는다.여기서투명이란,가시광선 투과율이 70%이상인것을의미한다.예컨대상기기재로는 PE^필름이사용될 수있다.

용액을기재위에코팅하고건조하거나,전술한화학식 1로표시되는화합물을 수지와함께압출하여 필름화함으로써제조될수있다.
[125] 상기수지용액중에는전술한화학식 1로표시되는화합물이용해되어 있기 때문에 화학식 1로표시되는화합물이용액중에균질하게분포하게된다.이는 별도의분산공정을필요로하는양자점 필름의제조공정과는상이하다.
[126] 상기화학식 1로표시되는화합물이용해된수지용액은용액중에 전술한 화학식 1로표시되는화합물이수지가녹아있는상태라면그제조방법은특별히 한정되지 않는다.

[131] 상기화학식 1로표시되는화합물이용해된수지용액을기재상에코팅하는 공정은롤투롤공정을이용할수있다.예컨대,기재가권취된롤로부터기재를 푼후,상기기재의일면에상기화학식 1로표시되는화합물이용해된수지 용액을코팅하고,건조한후,이를다시롤에권취하는공정으로수행될수있다. 롤투롤공정을이용하는경우,상기수지용액의점도를상기공정이가능한 범위로결정하는것이바람직하며,예컨대 2000?8내지 2,00 ?8범위내에서 결정할수있다.
