<p>PROBLEM TO BE SOLVED: To obtain a composition excellent in curability, tight adhesion and chemical resistance, having high coefficient of dynamic friction and having both non-slip characteristics and blocking resistance, by using as the constituents aluminum atoms bound through a primary bond, a chelate bond or a hydrogen bond, and unsaturated groups curable by actinic radiation. SOLUTION: This composition comprises, e.g. a resin which has a number- average molecular weight of 500 to 15,000 and whose skeleton contains unsaturated groups curable by actinic radiation, in an amount of 0.2-6 mol/kg in terms of solids concentration and Al atoms bound through a primary bond, a chelate bond or a hydrogen bond, in an amount of 0.1-10% solids by weight. This composition is obtained by esterifying a part of the polyol of, e.g. a polyester resin skeleton, a polyether resin skeleton or a polyurethane resin skeleton, or the epoxy groups of an epoxy resin skeleton with (meth)acrylic acid, and reacting the remaining hydroxyl groups with, e.g. trialkoxyaluminum.</p> |
