Summary

Optical bleaching agents on the basis of bis(5-alkylbenzenoxaol-2-il)aryles which compare well with world's best analogues.

Description

The methods of synthesis of a number of thermo- and light-fluorescent pigments, suitable for dyeing of various polymers and obtaining both coloured and colourless fluorescent fibres, have been developed. The technologies of production of luminophores with yellowish-green, blue, orange and red luminescence have been synthesized, developed and improved. These fluorescent dyes can also be used in manufacturing of printing inks for protection of documents and securities.

Technology type

Technical advantages and economic benefits

Developed optical bleaching agents compare well with world's best analogues. They are bis(5-alkilbenzoksazol-2-il)aryls obtained from domestic raw materials through condensation of aromatic diacids by alkilaminofenoles.

Technology differentiation and uniqueness
