Understanding Carbonless Copy Paper: Composition, Working Principle, and Applications

Introduction

Carbonless copy paper,  also known as NCR paper (No Carbon Required), is a type of chemically coated paper that enables the transfer of information through pressure—without the need for carbon sheets. It is commonly used for creating instant copies in multi-part forms.

Unlike traditional carbon paper, carbonless copy paper transfers information through pressure alone, making the process more efficient, cleaner, and environmentally friendly. The paper comes in multiple layers, each with a specific coating:

CB (Coated Back): This is the top sheet, coated on the back with microcapsules containing colorless dye.

CFB (Coated Front and Back): This is the middle sheet, coated with microcapsules on the back and color-developing agents on the front.

CF (Coated Front): This is the bottom sheet, coated on the front with a color-developer, typically clay or resin.

How Carbonless Copy Paper Works

The working principle of carbonless paper is based on a chemical reaction. When pressure is applied—through writing or printing—the microcapsules on the CB or CFB sheets rupture. The released colorless dye reacts with the color developer on the CF or CFB layer to form a visible mark. The resulting image is usually blue or black and is clear and long-lasting.

Key Features of Carbonless Copy Paper

Ink-Free Copying: No need for toner or ink, making the process cleaner and more efficient than traditional carbon paper.

Multi-Ply Duplication: A single press can produce 2 to 5 copies simultaneously.

Stable and Long-Lasting Image: The output remains legible over time, provided it’s stored in dark and dry environments.

Environmentally Friendly: Reduces toner usage and waste. However, some carbonless coatings may contain phenolic compounds, which should be responsibly recycled.
