The present invention concerns compound of formula (I) in the form of any one of its stereoisomers or as a mixture thereof, and wherein R 5 represents a n-butyl or a (3-methylbutan-2-yl) group. The use of compound of formula (I) as perfuming ingredient of the aldehydic type and the invention's compound as part of a perfuming composition or of a perfumed consumer product are also part of the present invention.
Provided is an adhesive which, in a metal foil-containing laminated composite film used in a high temperature sterilization treatment, is resistant to the effects of moisture in the air during curing, has good workability when used as a solvent-free adhesive, and exhibits excellent adhesive strength and acid resistance. Provided is a method for producing an adhesive composition, the method including: a step of obtaining an alcohol-added isocyanate (E) by reacting a trifunctional or higher isocyanate compound (C2) and a monofunctional alcohol compound (D) at an equivalence ratio of isocyanate groups in the trifunctional or higher isocyanate compound (C2) : monofunctional alcohol (D) = 100 mol% : 25 to 65 mol%, and a step of mixing a polyisocyanate (A) containing a trifunctional or higher polyisocyanate (C1) and the alcohol-added isocyanate (E), and an alcohol (B) having an acid value of 0.5 to 30 mgKOH/g, so that the equivalence ratio between isocyanate groups in the polyisocyanate (A) and hydroxyl groups in the alcohol (B) (isocyanate groups/hydroxyl groups) is within a range from 0.7 to 2.5.
Described herein is compound of formula (I)
in the form of any one of its stereoisomers or as a mixture thereof, wherein R represents a n-butyl or a (3-methylbutan-2-yl) group.

An electroluminescent (EL) device which has a light emitting layer including metal nanoparticles coated with an organic layer. The metal nanoparticles coated with the organic layer selectively remove an absorption band appearing at an excimer level without affecting a maximum absorption or emission wavelength, thereby enhancing the color purity and emission efficiency of the EL device.
