LUMINESCENT COMPOSITE COATINGS Russian patent published in 2014 - IPC C09K11/77 C09D5/26 

FIELD: chemistry.

SUBSTANCE: luminescent composite coatings contain polymer binding substances - high-strength heat-resistant poly(o-hydroxyamides) - products of polycondensation of isophthalic acid dichloride with 3,3'-dihydroxy-4,4'-diamino-diphenylmethane or isophthalic acid dichloride with a mixture of 3,3'-dihydroxy-4,4'-diaminodiphenylmethane with bis-(3-amino-propyl)-dimethyl-siloxane in an amide solvent, as well as a mixture of UV and anti-Stokes phosphors based on rare-earth elements. The coatings are dried at 100-120°C for 15-30 minutes after deposition. The coatings are stable over time and withstand cyclic thermal loads from -50 to +300°C.

EFFECT: ensuring stability of properties of the composite and parameters of the formed coating and uniformity of deposited coatings which have high adhesion to lavsan, polyimide, metals, crystals and other substrates.
