Title:
ELECTRON BEAM CURING TYPE COMPOSITION AND ELECTRON BEAM CURING TYPE OVERCOAT VARNISH
Document Type and Number:
Japanese Patent JP2022132010
Kind Code:
A
Abstract:
To provide an electron beam curing type composition that completely eliminates migration of a photoinitiator, reduces migration of an acrylate monomer, and can form a printed matter having a coating film which has less pinholes occurring therein, satisfactory gloss, satisfactory adhesiveness to a substrate, and satisfactory coating film strength such as rub resistance and solvent resistance.SOLUTION: An electron beam curing type composition includes a (meth)acrylate compound (A), and a solid wax (B). The (meth)acrylate compound (A) satisfies (1) to (3): (1) containing a trimethylolpropane alkylene oxide-modified triacrylate compound in an amount of 50 mass% or more based on the total amount of the composition; (2) containing a component having a weight-average molecular weight of less than 500, in an amount of less than 25 mass% based on the total amount of the composition; and (3) containing a trimethylolpropane alkylene oxide-modified triacrylate compound having a weight-average molecular weight of 1000 or more, in an amount of less than 35 mass% based on the total amount of the composition.SELECTED DRAWING: None
