PENETRATION AGENT FOR LUMINESCENCE DEFECTOSCOPY Russian patent published in 1997 - IPC

FIELD: luminescence defectoscopy. SUBSTANCE: penetration agent comprises luminophor-acceptor and luminophor-donor (4-methyl-7-diethylaminocoumarin is used as luminophor-donor) together with lypophile wetting agent (monoalkylphenyl ether of polyethylene glycol of C₈ - C₁₀-fraction is used as wetting agent), and solvent; wherein N-methoxypropylimide-4-methoxypropyl aminophthalic acid is used as said luminophor-acceptor and distilled water and N-methylpyrrolidone being used as said solvent. Penetration agent comprises, mas. %: N-methoxypropylimide of 4-methoxypropyl aminophthalic acid, 1.5-2.0; 4-methyl-7-diethylaminocoumarin, 0.3-0.7; monoalkylphenyl ether of polyethylene glycol of C₈ - C₁₀-fraction, 9.0-12.0; tripropylphenyl ether of polyethylene glycol, 15.0-25.0; distilled water, 10.0-22.0; N-methylpyrolidone, the balance. EFFECT: improved intensity of penetration agent, decreased its toxicity and increased its washing by water.
