Carbonless copy paper, often referred to as NCR (No Carbon Required) paper, revolutionized multi-part business forms by eliminating the need for carbon inserts. This innovation relies on a clever chemical system where microencapsulated dye, activated by pressure, creates an instant duplicate image on the sheet below. The performance of this system is highly dependent on the quality of the color-forming agent used, and NINGBO INNO PHARMCHEM CO.,LTD. is a key supplier of such essential components.

The principle behind carbonless copy paper involves two main types of coatings applied to the paper. The back of the top sheet is coated with microscopic capsules containing a colorless dye precursor, often a leuco dye like our Color Former 89331-94-2. The front of the sheet below is coated with a reactive developer, typically an acidic clay or phenolic resin. When pressure is applied – for instance, by writing or printing on the top sheet – the microcapsules rupture. This rupture releases the colorless dye precursor, which then flows into contact with the developer on the sheet below. The reaction between the dye precursor and the developer triggers a color change, forming a visible image that duplicates the impression made on the top sheet.

The choice of color former significantly influences the color, intensity, and permanence of the generated image. Our Color Former 89331-94-2, with its high purity and chemical stability, is an excellent candidate for this application. It readily reacts with common developers to produce clear, well-defined images, ensuring the integrity of multi-part forms, invoices, order forms, and other critical business documents. The consistent performance of this raw material from a reliable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. is essential for businesses that depend on accurate record-keeping and duplicate documentation.
