DERIVATIVES OF MALEIMIDE OR MALEIC ACID, METHODS OF THEIR SYNTHESIS, USE OF COMPOUNDS FOR PREPARING SUN-PROTECTIVE COMPOSITION, SUN-PROTECTIVE COMPOSITION AND METHOD OF SKIN SUN PROTECTION

摘要

organic chemistry. SUBSTANCE: invention describes compounds of the formula (I): X-R where X is Michael's acceptor; R is -alkyl-YZ, -alkenyl-YZ, -alkynyl-YZ where Y means O, NR4,S(O) n, C(O); n = 0-2; R4 is H, -alkyl, -alkenyl; Z means UV-chromophore group showing properties providing its use in sun-protective composition. Invention describes the use of the known compounds taken among of the above mentioned compounds for making the sun-protective composition and method of skin protection from sun effect. EFFECT: enhanced effectiveness of composition. 15 cl, 2 tbl, 2 dwg
