Abstract:
(EN) Provided is a photocurable composition containing a block isocyanate, a chain extender, and a photo-radical generator, the photocurable composition being characterized in that the block isocyanate is represented by general formula (1) A-B-C…. (In formula (1), A and C each independently represent a group represented by formula (2), and B represents a group represented by formula (3). In formula (2), R1 represents a hydrogen atom or a methyl group, R2 represents a C1-10 hydrocarbon group that may have a substituent, and L1 represents a C1-10 divalent hydrocarbon group that may have a substituent. In formula (3), R3, R4, and R5 each independently represent a C1-20 divalent hydrocarbon group that may have a substituent, a and b are integers satisfying 1≤a+b≤50, and either a or b may be 0.)
(FR) L'invention concerne une composition photodurcissable contenant un isocyanate séquencé, un agent d'allongement de chaîne et un générateur de photo-radicaux, la composition photodurcissable étant caractérisée en ce que l'isocyanate séquencé est représenté par la formule générale (1) A-B-C …. (Dans la formule (1), A et C représentent, chacun indépendamment, un groupe représenté par la formule (2) et B représente un groupe représenté par la formule (3). Dans la formule (2), R1 représente un atome d'hydrogène ou un groupe méthyle, R2 représente un groupe hydrocarboné en C1-10 qui peut présenter un substituant et L1 représente un groupe hydrocarboné bivalent en C1-10 qui peut présenter un substituant. Dans la formule (3), R3, R4 et R5 représentent, chacun indépendamment, un groupe hydrocarboné bivalent en C1-20 qui peut présenter un substituant, a et b sont des nombres entiers satisfaisant à 1≤a+b≤50 et l'un ou l'autre parmi a ou b peut être égal à 0.)
(JA) ブロックイソシアネートと、鎖延長剤と、光ラジカル発生剤と、を含有する光硬化性組成物であって、 前記ブロックイソシアネートが、下記一般式(1) A-B-C・・・(1) (式(1)中、AおよびCは各々独立して、下記式(2)で表される基を表し、Bは下記式(3)で表される基を表す。 ここで、式(2)中、Rは水素原子またはメチル基を表し、Rは置換基を有していてもよい炭素数1から10の炭化水素基を表し、Lは置換基を有していてもよい炭素数1から10の2価の炭化水素基を表す。また、式(3)中、R、R、およびRは各々独立に、置換基を有していてもよい炭素数1から20の2価の炭化水素基を表し、aおよびbはいずれか一方は0でもよい、1≦a+b≦50を満たす整数である。) で表されることを特徴とする。
