Abstract
본 발명은 복수의 플라스틱 시트를 합지시켜서 플라스틱 카드의 본체부(100)를 형성하고; 상기 플라스틱카드 본체부(100)의 전면 인쇄층의 위에 플라스틱-금속 간의 접착력이 양호한 에폭시 접착제를 형성하여 에폭시 접착층(110)을 형성하고; 상기 플라스틱카드 본체부(100)의 위에 형성된 에폭시 접착층(110)의 위에 박막의 금속성 메탈시트를 얹어놓고, 상기 에폭시 접착층(110)을 경화시켜서, 평탄하게 배열된 금속시트층(120)을 형성하며; 상기 금속시트층(120)의 위에 포토레지스트 필름을 부착시키고 노광시킨 다음, 금속성 에칭액으로 상기 금속시트층(120)을 부분적으로 부식시켜서 에칭작업을 실시하며; 상기 에칭 작업을 완료한 플라스틱카드 본체부(100) 및 금속시트층(120)을 수세 건조시켜서 금속디자인 형성물(125)을 형성하고; 상기 금속디자인 형성물(125)의 위에 투명보호층(150)을 형성하는 과정으로 진행되어진다.
Description
120: 금속시트층, 125: 금속디자인 형성물,
127: 식각 부분, 130: 금속성 에칭액,
140: 마스크, 150: 투명보호층
