Title:
AQUEOUS ULTRAVIOLET RADIATION-CURABLE OVERPRINT VARNISH COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2015/029878
Kind Code:
A1
Abstract:
The problem to be addressed by the present invention is to provide an aqueous ultraviolet radiation-curable overprint varnish composition that maintains a pleasantly soft velvet-like or suede-like texture on a base material such as a printed material. Provided is an aqueous ultraviolet radiation-curable overprint varnish composition which contains a urethane resin, an ultraviolet radiation-curable monomer that contains a water-soluble (meth)acrylate as an essential component, and water, and which is characterized in that the urethane resin:ultraviolet radiation-curable monomer weight ratio is 1:2 to 2:1, the coefficient of dynamic friction of a dried coated-surface is 0.1-0.7 after coating the aqueous ultraviolet radiation-curable overprint varnish composition, and if the measurement speed is increased from 2 mm/s to 20 mm/s, the percentage increase in the coefficient of dynamic friction is 10% or higher.
