Color Separations

hen someone tampers with or tries to remove an AuthentiCal color-changing label manufactured by William Frick & Co., Libertyville, IL, the polyester film's pressure-sensitive adhesive and printed pigment irreversibly separate into two colors. The label's color can be specified (i.e., purple into blue and red, green into blue and yellow). These labels reportedly are great for warranty, warehouse, safety, and security applications and work well on a wide variety of plastics, metals, and coatings. Visit www.fricknet.com.
