Title:
ULTRAVIOLET CURABLE COATING VARNISH COMPOSITION
Document Type and Number:
Japanese Patent JP2013087188
Kind Code:
A
Abstract:
To provide an ultraviolet curable coating varnish composition which is excellent in curability, scarcely brings about yellowing and is low in odor, in relation to an ultraviolet light-emitting diode (UV-LED) producing no ozone.
The ultraviolet curable coating varnish composition maintains a low yellowing property in an emission wavelength of a UV-LED lamp, even when using an amine-based compound and a photopolymerization initiator which possess a high yellowing property or in which the raw material itself is yellowishly-colored regardless of having high curability, by further compounding a purple pigment or a purple dye with an ultraviolet curable monomer and/or oligomer component and an acyl phosphine oxide-based polymerization initiator.
