PROBLEM TO BE SOLVED: To provide a thermo- or photo-setting composition having higher safety and stability in substitution for conventional thermo-setting compositions made from acrylates that give unfavorable influences on the human body such as skin irritation. SOLUTION: A thermo- or photo-setting composition contains one or more of unsaturated compounds described in the following formulas (A) to (C): (A) the unsaturated compound having not more than 500,000 of weight-average molecular weight being represented by general formula (1); R1-CH=CH-CH= CH-COO}1 R2} (1) (B) the unsaturated compound having not more than 500,000 of weight-average molecular weight being represented by general formula (2); R1-CH=CH-CH=CH-COO-CH2-CH(OH)-CH2-}m R3} (2), and (C) the unsaturated compound being represented by general formula (3); R1-CH=CH-CH= CH-COO-(R4-O-)n-R5 (3). In the above formula, R1 is a hydrogen atom or a 1-12C alkyl group; R2 is a monovalent organic group; R3 is an m-valent organic group; R4 is a hydrogen atom or -OC-CH=CH-CH=CH-R1; l and m are each independently an integer of not less than 1; and n is an integer of 1-30. |
