Abstract
An ultraviolet curable resin composition comprising (I) a saturated copolyester having a molecular weight of 2,000 to 15,000 which is soluble in a polymerizable compound (II), 20% by mole or more of saturated polycarboxylic acid components of the saturated copolyester being an aromatic dicarboxylic acid, (II) a polymerizable compound, at least a part of which is a compound having two or more polymerizable double bonds in the molecule thereof, and (III) a photosensitizer. The ultraviolet curable resin composition has excellent flexibility, adhesion and processability and is useful as an ink composition for screen printing and a transfer paper for decorating potteries and further as an adhesive for the preparation of laminated products.
