Laser marking pigments are added to plastics and inks and irradiated with YAG lasers to achieve high-contrast and fine printing. The pigment particles absorb the laser energy, causing the resin surrounding the pigment to carbonize, while the marking pigment itself turns black. This results in a laser marking pigment characterized by high blackness and fine (transparent) printing, requiring only minimal addition regardless of resin type or substrate shape. The laser marking market continues to grow due to its advantages, including ink-free systems, scratch resistance, versatility in surface design, anti-tampering and anti-counterfeiting properties, and high-quality, high-speed marking. Unfortunately, many common polymers are difficult to mark effectively because of insufficient absorption of the laser beam. Laser marking pigments developed by Kela provide excellent marking performance on various plastics and coatings at very low loading levels.
