Features And Benefits
Phthalide compounds, which are a type of colorless dye, develop color via a ring-opening reaction when interacted with acids. Because this reaction is reversible, decoloration occurs in a reversible manner under basic conditions. Pressure and heat sensitive recording systems utilize this color developing mechanism in which color formers, developers and sensitizers are intimately incorporated.
