Abstract
A color shifting heat transfer label includes a carrier and a color design layer on the carrier. The color design layer is formulated from an ink having a color shifting effect. The color design layer is configured to separate from the carrier to define a color shifting feature that is adhered to a target object upon application of heat and pressure. The color shifting feature is adhered to the target object to define a plane defined by the color shifting feature such that the color shifting feature exhibits a first color when viewed from an angle of about 90 degrees relative to the plane defined by the color shifting feature and a second color, different from the first color when viewed from an angle of about 45 degrees or less relative to the plane defined by the color shifting feature.
