PURPOSE:To prepare coating resin composition curable with actinic irradiation and having an increased curing rate and excellent adhesibity to bases, e.g. metals, glass, etc., by compounding a specific (meth)acryl-urethane resin having or more (meth)acryloyl groups with a specific copolymerizable monomer, etc. CONSTITUTION:A coating resin composition comprising (A) a (meth)acryl-urethane resin having two or more (meth)acryloyl groups and prepared by reacting (a) a (meth)acrylic ester derivative having an acid value of 0-10 and hydroxyl groups partially (meth)acrylated and prepared by condensing (meth)acrylic acid with a mixed glycol consisting of 5-85mol% of a 2-12C aliphatic glycol and 95- 15mol% of a terminal hydroxyl group-containing polyoxyalkylenebisphenol derivative expressed by the formula, with (b) a diisocyanate compound and (c) a hydroxyl group-containing (meth) acrylate compound, (B) a monomer having a double bond copolymerizable with (meth) acryloyl group of the component (A), and (C) a photosensitizer. |
