摘要

PROBLEM TO BE SOLVED: To provide an energy ray hardening composition having excellent extension of hardening membrane and having excellent rubfastness in a coating film after hardening.;SOLUTION: An active energy ray hardening composition contains at least two or more kind of monofunctional polymerizable compound and polyfunctional polymerizable compound. As the polyfunctional polymerizable compound, the active energy ray hardening composition contains a polymerizable compound A in which the number of functional groups is 2 or 3, average molecular weight is 500 or more and 5000 or less and glass transition temperature in a case of independent polymerization is 40°C or more. The content of monofunctional polymerizable compound in the active energy ray hardening composition is 60 mass% or more and 75 mass% or less. The content of polymerizable compound A in the active energy ray hardening composition is 3 mass% or more and 12 mass% or less. A polymerizable compound other than the polymerizable compound A has a composition ratio so that calculation value of glass transition temperature of polymer made of the polymerizable compound other than the polymerizable compound A is 25°C or more in FOX formula.;SELECTED DRAWING: None;COPYRIGHT: (C)2017,JPO&INPIT
