FIELD: radiation curable polymer compositions.

SUBSTANCE: proposed radiation-curable composition for application to the substrate, containing: (I) a radiation-curable component containing a compound having at least one (meth)acrylate group, and (II) a chlorinated inert polyester component that is derived from (A) a polyol component that is free from any compound derived from bisphenol A, and which is free from any compound cyclic simple etherpolyol, and the specified component of the polyol contains at least 5 wt.% of a polyol compound (Ai) which is cyclic and which has at least two hydroxyl groups, and (B) a polycarboxylic acid component containing a compound (Bi) having at least one chlorine group and at least two carboxyl groups, wherein the chlorine content of the chlorinated polyester (II) is between 5 and 75%, (C) optionally at least one monoalcohol compound, (D) optionally at least one monocarboxylic acid compound, (E) optionally at least one polycarboxylic acid compound substantially free of chlorine-containing groups, and (III) optionally an additional radiation-curable component containing at least one oligomeric compound having at least two radiation-curable ethylenically unsaturated groups. A composition of a coating, printing ink or varnish, and an adhesive composition containing the proposed composition, as well as a moulded article coated with the proposed composition, are also proposed.

EFFECT: proposed composition does not contain bisphenol A, which makes it favourable for the manufacture of food packaging.
