摘要： PURPOSE:To make it possible to peel in a film form a display part having a decorative print through an aqueous alkali treatment by a method wherein a print is made with a specified radiation-curable ink composition, the composition is radiation cured, and this procedure is then repeated a plurality of times. CONSTITUTION:An oligmer and/or polymer having a linear polyester skeleton and having 1 to 10 unsaturated double bonds in the molecule is mixed with a carboxylic acid (ester) and/or carboxamide having at least one acidic group and 1 to 10 unsaturated double bonds in the molecule and, e.g. a block copolymer of a fluorinated carboxylic acid ester having unsaturated double bonds and/or a fluoroalkylated polymer segment with a (meth)acrylic polymer to provide a vehicle. A print is made with a radiation-curable ink composition obtained by mixing the vehicle, a photopolymerization initiator, a photosensitizer, etc., the composition is radiation cured, and this procedure is then repeated a plurality of times to carry out printing on top of another.

摘要： PROBLEM TO BE SOLVED: To provide a peelable damping material adhering closely to an object to be adhered, sufficiently displaying damping performance, easily removable when recycled and usable by being mounted again. SOLUTION: When using the damping material 7 for the object 6 to be adhered, the damping material 7 is formed of adhesive non-vulcanized rubber, has a range of penetration of 30 to 100 (25 deg.C) and has closely adhering force of 5 to 20 N/25 mm (90 deg. peeling and speed 300 mm/min.) for a copper plate. The damping material 7 is closely adhered to the object 6 to be adhered and the damping material 7 is peeled from the object 6 to be adhered in a reusable state. The damping material 7 is formed of a damping material main body 8 and a restraining material 9 around the damping material main body 8, is sufficiently adhered to the object 6 to be adhered, displays damping performance, can be easily removed from the object 6 to be adhered after used, and the damping material 7 removed from the object 6 to be adhered can be used as it is as a damping material again without leaving residual dross of the damping material 7 on the object 6 to be adhered.
