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.
