Document Type and Number:

Japanese Patent JP7231424

Kind Code:

B2

Abstract:

To provide a technique for reducing a difference in curing shrinkage in a coating film of an ultraviolet curable enamel coating, to provide an enamel coating capable of being used by the technique, and to provide a cured coating film obtained by curing the enamel coating.SOLUTION: An ultraviolet curable coating composition contains: an ultraviolet curable compound (A) containing an ultraviolet curing resin or an oligomer (a1), and a 5 or more functional ethylenic unsaturated group-containing monomer (a2); a coloring pigment (B); and a photoinitiator (C) containing a photoinitiator (c1) having a maximum absorption wavelength in a region from a wavelength of 360 nm or more to 410 nm or less, and a photoinitiator (c2) having a maximum absorption wavelength in a region of a wavelength of 340 nm or less. In the ultraviolet curable coating composition, the coloring pigment (B) contains at least one kind selected from 0.01-1 mass% of a black pigment, 0.1-10 mass% of a red pigment, 0.1-3 mass% of a yellow pigment and 0.5-18 mass% of a white pigment based on non-volatile components of the composition. A technique related to the ultraviolet curable coating composition is also provided.SELECTED DRAWING: None
