    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.

    Abstract: Polyolefin moulding compsns. contg. (1) a thermoplastic, synthetic, high-polymer polyolefin and (2) 0.01 to 3 wt% (w.r.t. the polyolefin) of >=1 sensitisers of formula: cyclopentadienyl-Mn(CO)3, cyclopentadienyl-Co(CO)2, cyclopentadienyl-V(CO)4, cyclopentadienyl-Cr(CO)3 2, cyclopentadienyl-Mo(CO)3 2, cyclopentadienyl-W(CO)3 2, and/or cyclopentadienyl-Ni(CO)2 2. The high polymer olefins are polymers of e.g. ethylene or propylene from which disposable prods., e.g. packing foil, are produced in large quantities. Such polymers include polyethylene, polypropylene and polybutylene-(1). The polymers may also contain expanding agents for forming foamed prods., lubricating agents, pigments, dyes. The sensitisers may be used singly or as mixts. of >2. These additives may be incorporated into the polyolefin compsns. by conventional methods, e.g. using rolls or extruders. The compsns. can be moulded using conventional appts. The sensitisers accelerate the decompsn. of the polymer prods. under the influence of light without effecting other props. adversely.
