Reliable Colour Formers for Carbonless and Thermal Recording

When paper is coated with colour former formulations, a visible image is generated upon mechanical pressure (carbonless systems) or heat (thermal systems). These leuco dye technologies enable clean, fast, and durable imaging for receipts, tickets, barcode labels, lottery slips, special stationery and many other transaction documents.
NAGASE offers a comprehensive portfolio of black, blue, red and green colour formers with balanced sensitivity, background stability and lightfastness for diverse substrates and coating chemistries.
NAGASE supplies leuco dyes worldwide with technical guidance and documentation support for carbonless and thermal paper applications.

Applications

Leuco dyes enable pressure- and heat-activated imaging in transaction and specialty papers.

  • Carbonless paper (CB/CF/CFB) for multi-part business forms
  • Thermal paper for POS receipts, tickets and kiosks
  • Barcode labels and logistics tickets
  • Lottery and gaming tickets, parking stubs
  • Special stationery and security/traceable documents

Features

Colour formers engineered for high image density, stability and processing efficiency.

  • High image density – Deep, legible prints at low activation energy
  • Balanced sensitivity – Fast response under pressure or heat
  • Background cleanliness – Low fogging and good shelf stability
  • Color options – Black, blue, red and green grades for coding and design
  • Formulation compatibility – Suited for common developers/resins and coating lines

Frequently Asked Questions about Leuco Dyes (Colour Formers)

What are leuco dyes (colour formers)?
They are colorless or lightly colored compounds that develop a visible color after activation by pressure (carbonless) or heat (thermal).

Where are they used?
In carbonless and thermal papers for receipts, tickets, barcode labels, lottery slips, parking tickets and multi-part business forms.

How do carbonless systems work?
Microencapsulated colour formers rupture under pressure and react with a developer layer on the adjacent sheet to form an image.

How do thermal systems work?
Heat causes the colour former to react with a developer in the coating, producing a dark image without inks or ribbons.

Which colors are available?
NAGASE offers black, blue, red and green grades to meet readability and coding requirements.
