Abstract
Metal deco ink formulations are improved by the use of fluorescent dyes, UV-absorbing dyes and/or IR-absorbing dyes. These may be premixed with a phenol-formaldehyde resin without microencapsulation to protect the dye from other ink ingredients that have chemistries which are incompatible with that of the dye, in order to obtain photochromic ink formulation with a good shelf life.
