| abstract | Printing ink binders claimed in the Parent Patent contain (A) 30-75 wt.% resin soluble in organic solvents, (B) 5-55% at least one di-olefinic monomer, (C) 5-50% at least one olefinic co-monomer, and (D) 1-35% photo-polymersn. initiator. (B) contains at least 2 gps. per mol of formula CH2=CR-CONH-, (in which R is H or methyl), and (C) and (D) boil at over 180 degrees C Addnl. proportions claimed are 5-30 wt.% (A), 30-80% (B), 5-50% (C) and 1-35% (D). The binders are improved by >=60 wt.% of (C) being a reactive diluent of formula CH2=CR1-COOCH2CH(OH)CH2OR2OCH2CH(OH)CH20CO-CR1=CH2, (in which R1 is H, methyl or cyano, and R2 is a 1-8C bivalent gp, opt. contg. O and N. Smell is negligible, life of rubber printing rollers is not affected, and toxicity and skin irritation are substantially reduced. Pref. 100% of (C) is a reaction product of a diglycidyl ether of an aliphatic 2-6C diol or a 4-6C oxa-alkylene diol, with 1 mol (meth)acrylic acid per epoxide gp. Esp. pref. is the reaction product of butane diol diglycidyl ether with 2 mols acrylic acid. Amount of (C) in the binder mixt. is pref. |
