摘要： The present invention addresses the problem of providing a method for increasing the transdermal absorption of a water-soluble drug in a simple manner without relying on the formation of a prodrug of the water-soluble drug by organic synthesis. The present invention relates to: a complex which is formed from a water-soluble active ingredient and a fat-soluble compound having an aldehyde group through an interaction capable of being dissociated in water; a transdermally absorbable composition comprising the complex, a transdermal absorption controlling agent and a fat-soluble medium; and a method for controlling the release of the water-soluble active ingredient from the complex in skin.

摘要： [Problem] To provide a composition which can resolve the conflicting relationship between patternability, film formability, and high refractive index required for an optical waveguide-forming composition, and which can satisfy these requirements.
[Solution] An optical waveguide-forming composition comprising: a fluorene skeleton-containing epoxy compound (A) of the following Formula [1]:

(in Formula [1], L1 and L2 are each independently a naphthalenediyl group possibly having a substituent; and m and n are each independently an integer of 0 to 10); a monofunctional or bifunctional alicyclic epoxy compound (B); a monofunctional or bifunctional aromatic epoxy compound (C) different from the compound (A); and a photoacid generator (D), and an optical waveguide comprising a cured product of the optical waveguide-forming composition.
