Abstract

To provide a screen ink which exhibits stable printing properties enough to cause no defects in printed matter such as jaggedness, blur, pinholes or transparency and gives printed matter exhibiting high-grade specular gloss and color specular gloss. The special screen ink comprises 100 pts. wt. of a deposited aluminum pigment containing at least 75% of one having a thickness of at most 0.5 [mu]m and an area of 20-2,000 [mu]m2and, incorporated therewith at least, 10-1,000 pts. wt. of a binder polymer and 600-2,000 pts. wt. of one or more solvents having a boiling point of not lower than 112[deg.]C but not higher than 250[deg.]C, and has an ink viscosity of 100-2,500 cps (at 30[deg.]C).

Description

technical field [0001] The present invention relates to screen printing inks used in the production of printed matter having specular gloss or colored specular gloss, and to printed matter manufactured using the screen printing ink. Background technique [0002] It has been known to use inks that add various aluminum raw materials, such as flake aluminum, foil aluminum, and vapor-deposited aluminum pigments, to produce printed matter with a specular gloss. However, in the case of screen printing using such inks, There are problems such as zigzag pattern, cross-color, pinhole, and through-color defects in printed matter, and it is difficult to obtain stable mirror gloss and colored mirror gloss. [0003] Therefore, it is desirable to obtain screen printing inks with good printability and stable specular gloss or colored specular gloss. The screen printing ink with good printability mentioned here refers to the screen printing ink with very few defects such as zigzag pattern,...
