Abstract: The use of organosulfur compounds is claimed for bathochromic shifting of the UV/visible absorption spectrum of carotinoids. Independent claims are included for: (A) complexes comprising one or more organosulfur compounds and one or more carotinoids, and (B) preparation of carotinoid formulations, which comprises dispersion of an organosulfur/carotinoid mixture in water or a protective colloid solution, followed by drying of the dispersion.

Abstract: Prodn. of radiation-hardenable acrylate compsns. comprises: (i) the addn. of a cpd. (A) contg. acrylic gps. to a non-radically copolymerisable benzophenone deriv. contg. prim. or sec. amine gp(s), or OH gp. or mercapto gp.. Also claimed are: (1) radiation hardened materials contg. radiation hardenable acrylate compsns.; (2) benzophenone derivs. of formula RCOR (I) as novel cpds.; and (3) prepn. of the novel cpds. (I). R = phenyl or R ; R = a gp. of formula (II); and R -R = H, 1-4C alkyl or 1-4C alkoxy, with 1-3 of gps. R -R being a 1-30C organic gp. (X) with a prim. or sec. amine gp., OH gp. or mercapto gp..
