Document Type and Number:
WIPO Patent Application WO/2017/111472
Kind Code:
A1
Abstract:
The present invention relates to: a color ink composition for printed steel plates, the color ink composition having excellent adhesiveness, processability, and solvent resistance and the like with respect to steel plates; a method for manufacturing a printed steel plate using the color ink composition; and a printed steel plate manufactured according to the method. Specifically, the present invention relates to a color ink composition for steel material, the color ink composition comprising: 10 to 30 parts by weight of a mixture of a urethane acrylate oligomer and a different acrylate oligomer other than the urethane acrylate oligomer; 50 to 80 parts by weight of a photocurable monomer, which is a mixture of a monofunctional photocurable monomer and a difunctional or higher photocurable monomer; 5 to 20 parts by weight of a photoinitiator; 0.1 to 10 parts by weight of a pigment; and, in terms of dispersant solid content per 100 parts by weight of the pigment, 3 to 300 parts by weight of the dispersant, wherein the urethane acrylate oligomer and the different acrylate oligomer are mixed in a 1:1 to 10:1 weight ratio, and the monofunctional photocurable monomer and the difunctional or higher photocurable monomer are mixed in a 5:1 to 100:1 weight ratio. Moreover, the present invention specifically relates to a method for manufacturing a printed steel plate, the method comprising: a step for jetting, onto a steel plate, a color ink composition for steel plates; and a step for curing to form a print layer. Furthermore, the present invention specifically relates to a printed steel plate comprising: a steel plate; and a print layer formed on the steel plate using the color ink composition for steel plates according to the present invention.
