PROBLEM TO BE SOLVED: To obtain a new compound developable with an alkali, excellent in curability by heat, light and electron beam, providing a cured material having excellent heat resistance, flexibility, electrolytic corrosion resistance, etc. SOLUTION: This compound is shown by formula I (R1 is a residue after removal of two isocyanates from a diisocyanate compound; R2 is a residue after removal of two hydroxys from a diol compound; R3 is a bifunctional 5-21C hydrocarbon containing a bifunctional 5-12C alicyclic group; R4 is H or methyl; (n) is 0 or a positive integer). The compound is obtained by reacting a diisocyanate compound of the formula: OCN-R1-NCO (preferably an aliphatic diisocyanate compound) with a diol compound of the formula: HO-R2-OH (preferably polycarbonate diol, etc.) in the molar ratio of the former/the latter >1 and reacting the reaction product with a monovinylmonohydroxy compound (preferably 1,4-cyclohexanedimethanol monoacrylate). |
