The intricate chemistry behind advanced paper products plays a vital role in their functionality and market appeal. ODB-2, a specialized chemical intermediate, is at the forefront of enhancing the performance of thermal and carbonless papers. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier of ODB-2, is dedicated to understanding and providing this crucial component to meet the evolving demands of the paper industry.

ODB-2, chemically known as 2-Anilino-6-dibutylamino-3-methylfluoran, belongs to the class of leuco dyes. These dyes are characterized by their ability to change from a colorless or lightly colored state to a highly colored state when exposed to specific stimuli. In the case of ODB-2, these stimuli are heat (for thermal paper) or pressure (for carbonless paper). This property makes it an indispensable chemical intermediate for paper coatings.

The mechanism by which ODB-2 functions is through a color-forming reaction. In thermal paper, ODB-2, when heated in the presence of a developer (often an acidic substance like a phenolic resin or zinc salicylate) and a sensitizer, undergoes a molecular transformation that results in the absorption of visible light, appearing as a dark color, typically black. The purity of the ODB-2 directly influences the intensity, stability, and sensitivity of this color formation. Our commitment to high purity (≥99.0% by HPLC) ensures that when you buy ODB-2 from us, you are getting a chemical that performs reliably and consistently.

For carbonless paper, ODB-2 is encapsulated in microcapsules. When these capsules are ruptured by mechanical pressure, the ODB-2 dye is released, migrating to a reactive layer on the sheet below. This reaction between the ODB-2 and the developer then forms the visible colored mark. The effectiveness of this process is dependent on the ODB-2's solubility in the microcapsule fluid and its reactivity with the developer.

NINGBO INNO PHARMCHEM CO.,LTD., as a premier chemical manufacturer in China, focuses on producing ODB-2 that meets the stringent requirements of the paper industry. We understand that for businesses looking to purchase ODB-2, consistency in chemical properties is key to maintaining product quality and brand reputation.
