bedeuten, besitzen hypolipämische Wirkung. Sie können nach an sich bekannten Methoden ausgehend von den entsprechenden Esterverbindungen bzw. Säurehalogenidverbindungen hergestellt werden, wobei gegebenenfalls die sekundäre alkoholische Gruppe zur Ketogruppe oxidiert wird.
Novel spirooxazine compounds represented by general formula (A) or (A') are photochromic compounds having excellent resistance to fatigue due to repeated color changes and provide a choice of various hues. In said formulae the a ring represents a member selected from among 5-membered and 6-membered rings each having one nitrogen atom and optionally bound to a benzene or naphthalene ring, wherein the nitrogen atom is bound to a C1-20 alkyl group or the like; The β ring represents a benzene or naphthalene ring; X represents O,S, Se or N-R1 (wherein R' represents H, C1-20 alkyl, etc.): R2 and R3each represents OH, amino, C120 alkoxy, halogen or the like; and k represents an integer of 0 to 2.

The present invention provides the miniaturization and weight reduction of the multi-layer circuit board and improvement in the processability thereof. The multi-layer circuit board comprises a substrate
10
, on at least one surface of a substrate
10
, a first electrical conductive circuit (metal plating film
30
) disposed on the substrate
10
, an resin layer
20
disposed on the first electrical conductive circuit and a second electrical conductive circuit (metal plating film
30
) disposed on the resin layer. The resin layer
20
is composed of a resin compound including benzocyclobutene resin, particulate inorganic filler and ultraviolet absorbent.
