To obtain a resin composition having high stability, giving a cured product having faint color and good adhesivity and useful as a printing ink for screen printing, offset printing, gravure printing, intaglio printing, etc., by including a (meth)acrylic acid ester and an oligomer.
The objective composition contains (A) a (meth)acrylic acid ester of formula (R is H or methyl) (e.g. 2,3-carbonatopropyl acrylate) and (B) an oligomer [e.g. an epoxy (meth)acrylate]. The amounts of the components A and B are preferably 2-60 wt.% and 40-98 wt.% based on 100 wt.% of A+B, respectively. The composition may be further incorporated with preferably 0.1-15 wt.% photopolymerization initiator {e.g. 2-methyl-1-[4-(methylthio) phenyl]-2-morpholino-propan-1-one}.
