Abstract: This invention provides a photoreactive composition in which reaction of a hydrolyzable metal compound takes place by irradiation of light. A photoreactive composition, which comprises a hydrolyzable metal compound (A) comprising a metal atom and a hydrolyzable functional group bonded to the metal atom and, a compound (B) promoting reaction, polymerization or crosslinking of the compound (A) in the presence of oxygen by irradiation of light.

Abstract: The invention provides compounds which can generate amine by irradiation with light and are excellent both in photodecomposability and in reactivity and compatibility with amine-curable compounds, and photo-setting compositions containing the compounds. The compounds are carbamoyloxyimino compounds represented by the structural formula (I); and the compositions each comprise one or more of the carbamoyloxyimino compounds and an amine-curable compound. In the formula (I), R1 is an n-valent organic group; R2 and R3 are each hydrogen or an aromatic or aliphatic group; and n is an integer of 1 or above.

Abstract: An object of the invention is to provide a damping material resin composition which is great in loss tangent, exhibits outstanding damping properties and enables a damping material to retain its own shape. The invention provides a damping material resin composition comprising 100 parts by weight of a thermoplastic resin having a chlorine content of 20 to 70 wt. % and a weight average molecular weight of at least 400,000, and 100 to 1000 parts by weight of a chlorinated paraffin having a chlorine content of 30 to 75 wt. % and 12 to 50 carbon atoms. (Preferably, the chlorinated paraffin contains 10 to 70 wt. % of a chlorinated paraffin having a chlorine content of at least 70 wt. %.
