<P>PROBLEM TO BE SOLVED: To provide a copolymerized polyester polyurethane resin which provides an anchor coat layer which can improve the adhesiveness of an ultraviolet curable printing ink and the like to a substrate and has low blocking properties to the back side of the substrate, and to provide a coated film for printing having an anchor coat layer using the same. <P>SOLUTION: The copolymerized polyester polyurethane resin has a structure obtained by the polyaddition reaction of a specific polyesterdiol (a), a specific polyalkylene ether glycol (b), a specific aliphatic polyhydric alcohol (c) which is optionally used, and a diisocyanate compound (d), contains each of the components at a specific percentage, and has a number average molecular weight of 10,000-100,000. The coated film for printing has an anchor coat layer for printing provided on the outermost layer on one side of the substrate film, wherein the anchor coat layer for printing includes a crosslinked body of the copolymerized polyester polyurethane resin. <P>COPYRIGHT: (C)2011,JPO&INPIT |
