| Abstract | The present invention relates to an active energy ray curable composition comprising a maleimide derivative, which is useful for various coatings, inks for printings, surface finishes, moldings, laminated plates, adhesives, and binders. More specifically, the present invention relates to an active energy ray curable composition comprising a maleimide derivative which can be cured in the absence of a photoinitiator under irradiation of ultraviolet light with practical intensity and energy value of irradiating light, and a method for curing the said curable composition.
Objects of the present invention are the provision of an active energy ray curable composition which can be cured in the absence of a photoinitiator, and which can also be cured at practical light intensities and irradiating energy, and a method for curing the said curable composition; in which the composition comprises a maleimide derivative represented by formula (1): whereinm and n each represent an integer of 1 to 5, and the total of m and n is 6 or smaller,Rand Reach represent a linking group selected from the group consisting of {circle around (1)} an alkylene group, {circle around (2)} an alicyclic group, {circle around (3)} an arylalkylene group, and {circle around (4)} a cycloalkylalkyene group,Gand Geach represent an ester linkage selected from the group consisting of -COO- and -OCO-,Rrepresents a linking chain having an average molecular weight of 100 to 100,000 selected from the group consisting of (A) a (poly)ether linking chain and (B) a (poly)ester linking chain, in which at least one organic group selected from the group consisting of {circle around (1)} a straight chain alkylene group, {circle around (2)} a branched alkylene group, {circle around (3)} an alkylene group having a hydroxyl group, {circle around (4)} an alicyclic group, {circle around (5)} an aryl group, and {circle around (6)} an arylalkylene group is connected via at least one linkage selected from the group consisting of (a) an ether linkage and (b) an ester linkage. |
