Key technologies for CD-R
• Suitable adhesion to Silver layer
• Excellent durability
• Less color change under room light
• Low skin irritation
• Cost performance
CD-R protective laquer changes its color from clear to yellow by aging under room light or natural light. It's probably caused by Silver.
DIC's CD-R laquer is designed to prevent the yellowing problem.
