Dyes for the office supplies industry

 

Generally dyes for office supplies inks have to fulfill less strict purity criteria as dyes for ink-jet inks. Nevertheless, many requirements are very similar and ask for comparable characteristics and quality standards. In addition, with office supply inks there are special property profiles such as document fastness, fluorescent or erasable inks.

 
LANXESS offers water-soluble specialty dyes with high purity, specified surface tension and high color strength for the office supplies industry. The range also contains water and solvent soluble Nigrosine dyes. Furthermore, all BAYSCRIPT® colorants can be employed advantageously for high-qualtity inks in the office supplies industry.
 
Particularly important in the office supplies industry is the compliance with the statutory ecological standards which lay down the limits, e.g. for heavy metals or free aromatic amines. For most LANXESS colorants of the ranges for ink-jet and office supplies inks the compliance with corresponding limits are specified and documented in the certificate of analysis for every batch.
Further detail information can be taken from our technical data sheets and product specifications.
