PURPOSE:To obtain the title ink improved in an ability to prevent scumming and in printability by mixing a desensitizer with a filler and a vehicle as principal components to obtain an ink of a specified viscosity. CONSTITUTION:20-60wt.% desensitizer (A) (e.g., a product formed by esterifying 1/6 of the terminal OH groups of a polypropylene glycol/ethylene oxide (4mol) adduct with oleic acid) is mixed with 10-40wt.% filler (B) (e.g., titanium oxide) and 20-80wt.% vehicle (C) comprising 10-40wt.% resin (e.g., rosin-modified phenolic resin), 5-20wt.% oil (e.g., linseed oil) and 5-20wt.% solvent (e.g., petroleum- derived solvent) to obtain the title ink of a viscosity >=500P. |
